Hi, this is exactly waht I was lookign for. But I have question: is this BluePower charger enough to feed the 12V devices when on external power supply (110/230V)? Is the BluePower charger capable to work as power supply for lights etc? Thanks for help, video is awesome. Liked and subscribed.

[@rosslukeman]

Hi @@petos0 this charger puts out about 400 watts, so if your 12V loads are less than that, then yes it will run them on its own, with the remaining power going into your batteries. That's in the charger mode. It does have a "power supply" mode as well, where instead of going through multi-stage charging, it will just put out a stable set voltage, a voltage chosen by the end user. Hope that helps, thanks for tuning in!

[@eladsgarr]

@@rosslukemandoesn’t using and inverter charger prevent you from this roundabout method of wiring this system.

[@rosslukeman]

@@eladsgarr yes the inverter charger does all of this on its own, the inverter, the charger, the transfer switch, all in one package. At the end of the video I tell people to go that route if they are doing a new system.

I just finished installing a small solar system in a 1973 15x7 camper. My wife was asking me how to connect to shore power and solar also. This video explained it clearly for her to understand. Great video. Stay safe and vigilant.

[@rosslukeman]

Awesome to hear this video helped her! Congrats on finishing your system, and thanks for tuning in!

[@memohughes7463]

This is the first video that covers 99% of my questions about this process. Not only do you explain what the single-unit inverter/charger does, but you also offer alternative solutions for upgrading existing systems. I’ve seen manual versions of the shore power switch when I was overseas, but I love the idea of an automatic switch that decides to use shore power when available. I also like the way you set up the battery charger. Great stuff and great video! I’m kind of curious about scenarios where you would be hooked up to shore power, but not want to have the charger topping off your batteries. 🤔 Thank you!

[@rosslukeman]

Hi Memo, thanks for tuning in and great to hear you got a lot out of the video! On the charger on-off option, perhaps it is rare, but I just don't like having to charge the batteries every time I decide to plug in. The charger switch is an extra layer of control, that perhaps could be left out if the end user doesn't care about that. It's not a must-have and could work either way. Great question and thanks again for stopping by-

[@herkko61]

The whole picture starts to become clear now to me. This is how I want my system work. If there were only one video from you, this would be it! Thank you so much again! :)

Great video showing everything is a clear and understandable way. My system doesn't has AC requirement on the road, so I am thinking of Victron Energy Blue 30A AC charger powered by shore power, protected by the 30A breaker box ... . Can you advise where you get the Breaker box? I figure the "pilot switch" and outlet can be sourced anywhere and go in a 2 gang plastic box.

thanks a lot! this video helped me kinda think out and solidify my plans for my fully 12v system (with just a little cigarette lighter inverter for my laptop). line1=solar panels>charge controller>battery bank line 2=shore power>battery charger and breaker panel so i can charge my laptop and drone and everything without draining my battery bank when hookups are available

[@michaeldesmit5577]

Great video Ross. I have a couple of questions about a solar system I installed in my rv. I used two bus bars to connect everything in the system. My first question is on the negative bus bar. All of the components are also grounded to the neagtive bus bar as well. Should that bus bar be grounded to the chassis ground of the rv? The 2nd question is about seperating the two chargers that can charge the batteries. I have same transfer switch used to switch from show power and solar power, wired the same way you did. I also have an internal battery charger housed in the circuit breaker a/c d/c distribution panel. I have two batter switches in the system, one to turn on the dc power to the inverter and also allows the charge controller to charge the batteries. I have the other battery switch between the dc charger cord coming from the AC DC distrubution box to the batter bank to charge when on shore power. So, I dont overcharge the batteries and have a continiuos loop, When Im on shore power, I turn off the battery switch coming from the solar charge controler so it cant charge the batteries and open the battery switch coming from the ac dc distribution box that has the charger in it to charge the batteries and supply 12 v to the system when I am connected to shore power. Is there a better way to wire this? Thanks

Thanks for the tip to connect the charger directly to the mains wiring in the switch. I've wired it from the breaker so I need to make sure to turn it off when I turn on the inverter so it doesnt have a "free energy" loop lol

Rigging a bus right now for a job where i will have shore power and take short camping trips, i think im gonna do almost this exact setup just without the solar charging until i make a bit more money

[@ZaiLH]

Very nice presentation. Since its for a vehicle it would have been nice to have the alternator included. Would you add that from eg Orion on to the same +/- bus bar's as the MPPT and BlueSmart chargers?

[@rosslukeman]

Thanks, glad you found the video useful. The answer is yes, you would connect the Orion to the same +/- bus bars as the other chargers.

[@eduardoguzman8868]

Good afternoon sir, really liked your video. I was thinking about upgrading my set up which is really similar to what you have right now. I was looking forward to purchase additional batteries but I'm not sure if the charger that you are using in the video will work with multiple batteries in parallel.

Hey Josh, thanks for subscribing and picking up the cheat sheet and VC Framework. I appreciate your support. More to come!

[@thetruthserum2816]

Eventually, some manufacturer will put all of these components into 1 device, and that will become the new normal... MPPT, Inverter, Charger, Shore Power Transfer, Shunt, Lightning protection, all in one... The reason why it will work is because most system components are "sized alike". Another option to keep some modularity to it would be to do it like PC's do with "card slots", so that the MPPT could be an edge card inserted into a mainboard, thus allowing some flexibility in design while shrinking the wiring bird's nest into one box with slot cards on a motherboard...

[@tehdreamer]

Victron Multi Plus does the charging and the inverting in one unit. Would deffo get it next time since the charging on those units is pretty powerful (50A and more) plus a good inverter. Now i just have the 30a Victron Charger plus a different brand inverter.

[@rocketbmw]

The Sol-Ark has most of those features.

[@Canoecamper]

Right on! In my perfect world, a camper van I outfit would have one huge-capacity battery box hardwired to a 30 amp cord that I plug in at home to charge to capacity. It would then be hardwired into a square D 30 amp circuit breaker box on into two separate circuits. The battery would have enough KWHs that I could run everything on house current (except maybe heat and air) for a week. Then I go home to recharge or, if on a longer trip, I get an electrical campsite for one night to recharge for another week. Is such a thing possible yet?

[@lostcoyote541]

Ross this video was very thorough thank you. This may be a dumb question but I’m adding shore power, same as you have done. I want to loop back to charge my batteries when needed but I only have a Renogy Dc to Dc charger for the alternator. Do I need an Ac to Dc battery charger? Or a converter and just plug into my existing Dc to Dc? Thanks in advance

[@ToddRichardson-ln7uy]

Ross, awesome video. I built my van to be totally off grid, but thinking I want to add a/c. Where would I wire the a/c unit into this system?

[@craigbrowning9448]

I have my shore power set up so I can entirely or partially bypass the house power when charging. This allows under ideal shore power situations to be able to give the house system arrest after charging, or in situations like when you're plugged into someone's residence to keep higher current items (like I microwave) on the house power so you don't blow the circuit breaker in the residence.

[@DJWilkstar]

Thanks for this bud I must have watched this 100x

[@rosslukeman]

Wow, thanks for tuning in, great to hear this was helpful!

[@flynryan3053]

If the inverter itself has an on/off switch built into the case you could always open the case and run a much smaller wire to a light duty switch that splices into the case switch. But you would not get the indicator light like you would in his setup. That transfer switch is huge, smaller ones?

[@jjhunter7377]

Hey Ross what size battery did you use for this demonstration? I am adding something small to my minivan just to run my cpap at night and a small fan. I think this exact setup would work just fine for that. Thanks for the great explanation!

[@ECMVAQ137]

I like your teaching skills, just remember it's OK to slow down on certain "component hookup" however you are very helpful. ✌

[@rosslukeman]

Thanks for tuning in and for the feedback! Sometimes I get comments that I drone on too long. I guess it comes down to different people liking different styles. In general I don't mind making more drawn out explanations. Good to hear that's your style.

[@applesbighatranch6906]

Subscribed! although in my small RV trailer (a 5' X 10' squaredrop) I am building pretty much this exact system, but using a Samlex 30A transfer switch. This one has two fused 120V outlets for a battery charger and whatever else. I'm using the second plug as the 120V source for my reliable, old Engel compressor fridge. I have already installed a 15A 120V light switch to better control my shore charger so it was nice to see Ross suggest this. Now I know I'm not totally nuts. hahaha... QUESTION: Chassis grounding! Can you make or do you already have a vid explanation on this topic? For example, grounding my Samlex 1500W pure sine wave inverter using 1/0 (yes, as it's case ground)... do I want to run a separate, negative ground buss bar and then run that to my trailer frame? If my inverter were to fault then send 150 amps into my trailer frame, would that possibly damage the powertrain control module of the tow vehicle (if still hitched, chained, etc to it). Thanks Ross! You are the man!

[@derekreager]

I appreciate this video very much-thanks! I’m working on an experimental project that is essentially a portable version of this setup. My concern is proper grounding, any thoughts? My first thought is it’s properly grounded to vehicle when charging via DC-DC charging system. Is that true? But while connected to shore, maybe some sort of connector to a vehicle ground? How about when out of the vehicle (in house) charging via AC? Outlet grounding sufficient? How about outside solar charging? Maybe some sort of ground rod I shove into ground via the aforementioned connector? Lots of questions, sorry. But they’re all regarding proper grounding for a portable unit. Any input is appreciated. Thanks!

[@elliottasbury4667]

This video was SUPER helpful! Thank you! Quick Q - instead of splicing the charger into the shore feed at the transfer switch, do you have any thoughts on adding a 110v outlet inline with the shore feed before it gets to transfer switch? Reason being, my AC to DC charger is already wired with a type b plug.

[@brianeyman316]

This is a great explanation. But I'd like more information. I've got a old sliding truck camper that's got existing wiring power breaker panel. What I want to do is take all my solar components ie-solar panels,mppt,100w inverter, lithium batteries,b2b charger, and fuse block that I stripped from my van and plan on putting it in the camper. I know how to connect all the solar components together I just don't know how to tie it into the existing camp or electrical and what do I do with the existing battery in the camper. I understand the transfer switch part but how do I connect it to the RV breaker panel? And what do I do with the old existing AGM battery? Also can I connect lithium and AGM batteries together?

[@rosslukeman]

Hi Brian, thanks for checking out my video. I would be glad to help with this but it's beyond a KZbin comment. I would be glad to work with you as a student of my electrical training, or via consulting. Here are those links: www.rosslukeman.com/offerings www.rosslukeman.com/vanpower Thank you, Ross Lukeman

Is there anyway to get a wifi signal from this system? Your videos take things slow enough for me to understand. True educator. Thanks

[@rosslukeman]

Hi John, thanks for the kind words, I'm glad you're enjoying the videos! As far as WiFi specifically, no, none of the components shown here emit or communicate with WiFi signals. There are a couple that do Bluetooth, but that's all. For the Victron components in the video, they could be connected to a Victron GX device, and those devices will pick up a WiFi signal, if one is available. Hope that answers your question, thanks-

[@denotsironlion67]

Are you able to use a 3 way connector & Tie in both Shore & On board Generator to that dynamic part of the Transfer Switch? Just trying to figure how to incorporate the generator with solar and shore

[@beijing561]

Very good video. But how to set up the shore power and generator together? There are times you don't have shoure and use generator. You said when generator is used, the shore hooks up in the bottom and the generator goes to the dynamic, but ehere does the inverter go? Can it be one wire for both genrator and the shore? Just make a inlet box where generator and shore can plug in alternately, no?

[@kevinkcheng]

I have the same question as you! With OP current setup, what happens if you connect a generator to the shore power plug? Will this set up still function and will there be a 30 sec delay for the generator power?

[@JAYBLAK00]

This is a really well made video. I love it!

[@rosslukeman]

Thanks!

[@johnny5620]

I just subscribed. Ever since I hooked up PV solar to my trailer, my battery won't power my interior lights, pumps, or radio. I'm guessing I need a transfer switch. I had shore power connected to trailer while my pv solar system was going. I don't know if the both of them running together fried my original factory system. I'll check fuses. I have the Renogy 40 amp charge controller with Bluetooth. I don't know what happened.

[@randystern7870]

With respect to this excellent video, for a fraction of the cost of the victron inverter/charger why not just add another 30 amp charger and a much larger inverter? Thanks

[@rosslukeman]

Because these systems are already complicated, you're not going to save that much, and people do double the engineering to save a few dollars. It would work, just not my style.

[@lechimera99]

Great video! I have a stand-alone system in my Travato, all it needs is the shore power added, this really covers it. My Renogy DC-DC controller has a bluetooth monitor feature, do I need to install the shunt on neg connection to the AC-DC charger and put another monitor there? I kinda don't think so, not sure, I don't know what the shunt does.

[@rosslukeman]

Hey Alan, thanks for stopping in, I'm glad you enjoyed the video! In general if you have a shunt it's for the battery monitor, and it will go in the negative line right before that line hits the battery or batteries. It's just monitoring current in or out of the batteries, so it can tell you how much "fuel" you have left in the "tank" so to speak. I did this video on battery monitors if you want to see a shunt being installed: kzbin.info/www/bejne/rIWuc4GYYsh9p5Y Hope that helps, good luck with it!

[@johnthornley6168]

Most impressive explanation I've seen. Well done!

[@gabrielglouw3589]

Do I need the transfer switch if I don’t plan power devices and charge the batteries at the same time? I’m building a hand truck solar generator and I’d like the convenience of ac and solar charging. Can I have a solar charge controller and the AC charger on the same system if I only use the wall socket to charge when everything else is disconnected?

[@briannix5572]

So we have a mobile detailing business. We run mostly on generator, but want the option to use shore power on occasion. Could I use the generator as the main source and shore power as secondary? So the shore power would go in the middle connection?

[@davidpatrick1813]

I have a 12 I 1200 victron inverter. I just added it to an old rig I'm working on and when I plug in a clock radio the radio buzzes a lot when it is moved within about 3' of the inverter. I have yet to wire in the inverter for 120 in the camper and switch it on and off ... great video about this transfer switch. I was thinking of a rotary switch to go from one and the other. I am looking too make a switch to select between two different solar panel configuration as not to put in too much into my victron 220 W 15 amp controller. I may be parked under trees and want to use portable panels in the sunlight...

[@rosslukeman]

Hi David, interesting to hear about the clock radio buzzing when it gets close to the inverter. I will take note. On the rotary switch, it is the same functionality and I have dealt with vans using those (Blue Sea Systems has some switches like that), but I try to automate the system as much as possible so the user doesn't have to do things manually. I like your idea though on the solar panel switch. Mixing different banks of panels can be tricky and it seems clean to switch from one to the other based on conditions...Thanks for the comment!

[@dharnish256]

This is so far the closest to what I'm trying to accomplish, just without the charger. Have a 5th wheel... adding solar panels and Lith batteries. How would I bypass the trailers invertor/convertor to make this setup work? Would I need a breaker switch like you show for shore power? Or was that just for demonstration purposes?

[@rosslukeman]

Hi Daly, on the breaker, I tend to add my own for shore power input, but there will be one out at the power pole you plug into as well. The rest of your question is kind of difficult to answer without knowing what you have, and is beyond the scope of KZbin comments. If you would like consulting and perhaps a hand sketch, I have that available here: www.rosslukeman.com/offers/Au4HykMc Thanks for tuning in!

[@danemmerich6775]

Great Video Ross. So informative. I have one question. Isn’t the PD converter charger, a charger? You have a separate battery charger correct? Do you need that if you have the PD converter charger which charges the battery when hooked up to shore power.

[@rosslukeman]

Thanks for tuning in Dan, great to hear you enjoyed the video! On the PD converter, yes that is just a battery charger built into the Progressive Dynamics distribution box. It's just a charger (120V to 12V). I guess the name is related to the inverter (12V to 120V). But yeah, sounds like you already have a charger. Hope that helps!

[@dustinrhodes2763]

If instead of the batteries, inverters, chargers, and all of that, if I used this transfer switch to connect a 30 amp battery bank like an Eco flow Delta pro and the other side of the switch being a standard 30 amp shore power. Would the fact that the battery bank having a floating neutral, cause an issue with the AC power in my camper? The reason I ask, is that EcoFlow sells an adapter that changes the battery bank from floating to bonded neutral, and I’m curious if it’s necessary in this configuration with the ground being connected to the frame of the camper?

[@tehdreamer]

A simple manual transfer switch is much cheaper but ye automated is nice. Maybe updated for the future on my camper.

[@pamtilsonrodgers2825]

You explain things so well. Tfs.

[@rosslukeman]

Thank you Pam!

[@johnspeaks54]

the only question i have is instead of the 3 way connector could you use a 4 way and add a generator to that mix where its either or for shore or gen or if the back feed may damage the other component

[@stefanteubes2247]

Love your explanations. How can I combine solar to a Victron Multiplus?

[@nmartin5551]

[@guoyongzheng]

Can you teach me? I don't have a solar charger but my RV has a generator, please let me know how do I connect the inverter, generator and shore power to the ATS? Thanks in advance for your help.

[@tikicowboy]

Awesome video!!! I also have a Generator in my van. How do I add that + alternator + shore power? Would I need a 3 way transfer switch?

[@rosslukeman]

Hi Herb, you would plug in shore power and the generator into one of these transfer switches. The alternator wouldn't go through the transfer switch, it would just connect to system positive and negative, the 12V part of the system that links to the batteries.

[@Pit8800]

I'm bit confused about last bit you've mentioned in your video - EasyPlus switching off inverter when you plug in shore power. I've got EasyPlus Compact 12/1600/70 and need it to be switched ON to pass through shore power from the grid to the van. So in my set up I'm hooking up to the grid, switching Easy Plus "On" and I get 230V in all sockets on board. At the same time charger side kicks in and is topping up my Lifepo battery. My problem is, in a cold weather BMS will protect battery and cut off charging which for some reason makes easy plus cut off shore power. What I'm doing wrong? Why inverter / charger side can't be off and just pass through 230V from the grid. That was my whole point of having easy plus compact with beakers fitted to simplify install. Thanks for very informative video.

[@rosslukeman]

Hi Pete, I was saying that the inverter-charger will turn off its internal inverter when it detects shore power, but as you concluded the unit itself is left on by the user. On the BMS shutting down everything, that sort of makes sense that even the 230V grid power could not get in. Do you have a Victron BMS that's controlling the EasyPlus? An easy fix may just be to have a little heating pad on the batteries to prevent this shutdown from happening. Whether the EasyPlus can let shore power through while turning off battery charging, I am not sure. Perhaps there is a setting for this in the programming. You might also ask in the Victron Community forum. As I mentioned though, you might get a battery heater to avoid the situation altogether. I hope that helps! Thanks, Ross

[@kustomdeluxe8489]

I'll just break the tang that connects the 2 outlets on the receptacle. Wire one to shore power and one to inverter, plug in appliance to either one as needed. I don't do anything in a van that requires uninterrupted power, save money and space by not getting a transfer switch. Wire 1\2 of the outlets to a junction box connected to a shore power outlet and the other 1/2 to the inverter.

[@gracehurst4141]

Hey Ross I love your videos and the way you explain everything! I actually followed the same system you show in the video in my van, the only part I need help with is wiring to the distribution panel. I bought the one you recommended but am wondering do I wire both the transfer switch and inverter to the distribution box? And can I use the outlet on the back of the box to connect either the transfer switch or inverter? Sorry, these might be simple questions but I'd appreciate the help, thanks!

[@JoshJorg44]

So you can only run certain things off the solar 12-volt system, and so you would not be able to run something like an air conditioner off of it. My question is, if you had a generator to power things like an air conditioner when you didn't have Shore power, how would you set it up so that you could have your air conditioner running off your generator, but everything else running off the solar system ?

[@traylorkarttech4432]

I am about to set up a van for racing karts (not much for camping). I currently use a trailer with a 120v AC system and I power it with a generator. With the van I don’t want to take my larger generator and would like to just carry my 3000 watt generator. Is there additional issues with using the generator in place of the shore power? Is the transfer switch enough? Ha. I just got to that point in the video. So I’d have a plug for grid power and a plug for generators?

[@mrbranchatl]

great explanation.... thanks for the help

[@rosslukeman]

Thanks Steven, I'm glad that was helpful!

[@timvandergriff2111]

So what if you want shore power sometimes and generator power other times through the shore power plug on an RV? Do you have to change the relay everytime?

[@rosslukeman]

Hi Tim, if you want to send the generator or grid power through the same plug, I would just say to wire that inlet to the generator side of the transfer switch so you get the 30-second generator startup delay from the switch, no matter what you plug into your inlet. The other side of the switch would be your inverter. Great question.

[@timvandergriff2111]

[@tmo7984]

Hi Ross, thank you for the great videos! Quick question, also it might be a dumb question... When I syphon off power for my charger, does it affect the charger's output? I will be running a Progressive Dynamics PD9160ALV 12V Lithium Ion Battery Converter/Charger - 60 Amp. Just want to make sure my "tapping" into the lines the way you show it wont affect anything.

Ross, thanks for your videos. Quick question on this one - I saw you have the chargers on the switched side of the batteries. Any reason for that? I thought it'd be better to have the chargers on a separate switch than house supply (so you can kill supply but still have batteries charging etc.) Or were you just being efficient for the purpose of the video?

[@rosslukeman]

Hi Nick, I suppose there is a bit of an art to it, and you could arrange the switches differently if you had a reason. I typically have a "battery isolation switch" as I call it, so that I can isolate the batteries when the system (in this case "the van") is not being used, and I want to prevent any parasitic loads from taking the battery down over a long duration. This switch also removes battery power from the system during maintenance and installations. I think it could be good to have chargers and loads on separate switches, although I try to make these systems as simple as I can. As I said it's sort of an art so no two electrical designers would come up with the same layout. It's whatever you think is best for the outcome/operability you want to create. Hope that helps!

[@travisclarke1797]

Great setup up. How can I have A/C shore power turn on only when my battery dies?

[@rosslukeman]

Thanks Travis, I'm not quite sure on your question. Typically if shore power is available you run your rig on that power. Being plugged in but running on your battery until it dies instead is not a use-case that anyone designs systems for. I suppose it could be done. You would probably have a battery monitor set to trigger its relay at some low-battery setpoint (BMV-712 has a relay like this). When the relay went off it would turn on the inverter-charger (or perhaps just a charger like we had in this video).

@@rosslukeman This seems to be what I'd also like configured, because while I have my trailer at home and plugged into shore power, I'd prefer that AC is being pulled from my inverter (powered by my batteries, and getting charged from solar) instead of paying the power company. And then if/when my batteries are too low to be used, either because there's no solar charging (or insufficient solar charging), or my AC is pulling more than my batteries & inverter can continue to support, it's at this point I'd like my shore power to kick in. The reason for this use case is to take advantage of the solar/batteries/inverter for my AC needs (as much as possible) instead of pulling from and paying to my power company. For this use case, I've also incorporated an ATS so that when my batteries (currently AGM) get down to about 94%, the ATS relay switches from the inverter supplying AC, over to shore power supplying AC. Side note and not directly related to this use case, of course I'd much rather have LiFePO4 batteries, and I plan to switch to them at some future date as they'd work out so much better and longer. Now what I'd also like to do in my system is that when my ATS has switched to shore power, *and* if there's no or insufficient solar power, then allow for shore power to supply to a battery charger that would recharge my batteries.

Brilliant simple explanation thanks 👊👍

[@stevenwood7131]

do they have a 4 power source transfer switch? I want to run off : *Shore Power * Solar *LiFePo House battery *Alternator. Mostly i want DC Circuits ( lights, Propane Furnace, propane shower/Water heater/Stove top, and Freshwater heater pads, and maybe 2 AC 120v Plugs recept.

[@douggee3610]

Do I need the on switch before the breaker box as they have all the breakers built in

[@thelongandskinnyone]

hey at 14:30 do we need the three way connectors if the ground is actually running out the bottom left of the box?

[@rosslukeman]

Hi there, the ground has nothing to do with the 3-way connectors. No grounds go in those connectors.

[@gqm5450]

If you were to stay using a 12v system, ie. a cargo trailer with lights, could you simply remove the inverter and solar charger from the system and operate the same with the switch and charger?

[@rosslukeman]

Hey there, yes the systems are largely modular. Everything operates on its own and can be added or removed, and the other stuff still works. If you need real help, check out rosslukeman.com for more resources. Hope that helps, thanks for tuning in!

I hope you could answer me this, WHAT SIZE COPPER WIRE SHOULD I USE TO CONNECT TWO 12 VOLT 230 AMP HOUR BATTERIES TOGETHER? I have a 1000 watt inverter 2 200watt solar panels a 230 amp hour 12-volt batt and am adding a second Batt of same size ?

[@rosslukeman]

I would use the fuse and cable size specified by the inverter, as your minimum fuse/cable size for your batteries. That's your largest load, so the cable size that works for your inverter, could be carried all the way back to the batteries, since that's the source of the power. Hope that helps-

[@Victoria-ji2hj]

I plan on always being plugged into shore power (with potentially adding solar). What all would you recommend if you/anyone has advice i would appreciate it!

[@darrylt5300]

So I have a question I have a 50 amp 5th wheel and I have a shore power plug in the far back of the trailer and I want to add another shore power plug closer to the convince center on the side of the trailer the original plug wire goes to a surge guard in the storage bay in and out to the Victron Multi plus 2 then to the main panel so what do I need to NOT remove the original shore power inlet plug but to have both plugs work if I chose to plug into one or the other? Having the option of both locations.

I am wanting to add shore power to my van. I already have the Renogy DCC50S DC-DC Charger installed. It runs the charging from my solar and alternator to the house batteries. Can I use the TS-30 Transfer Switch to add a Progressive Dynamics Mighty Mini AC/DC Panel and Converter/Smart Charger into my system. The end result I am looking for is to have 3 options for charging my house batteries. i.e. shore, alternator, and solar.

[@rosslukeman]

I could be wrong but I don't think that Mighty Mini is the right product. It will have a single line in from the Transfer Switch. Problem is...when you unplug and run the inverter into the transfer switch, it's going to think it has shore power and turn on the converter to charge your batteries. So your batteries will charge your batteries, can't have a loop like that. You should just get a charger and a naked AC/DC panel like the PD5000 or the WFCO 8930/50. That's my quick take on it.

[@explorebelow5528]

​@@rosslukeman If I understand you correctly, I would hook my DCC50S DC-DC Charger to the Default Power Source Wires on the DS30 Transfer Switch, and the ac-dc converter charger would be hooked to the Dynamic Source Wires on the DS30 Transfer Switch. The Transfer switch would then figure out if I was hooked to shore power, or if I was powering from the DCC50S DC-DC Charger, and send output power to my Battery Bank, which would send power through my inverter and ut to my 120v and 12v outlets?

[@philsharpe5392]

Hi, sorry to ask such a specific question but you obviously know what you're talking about and i'm pretty clueless. I have an Sargent ec160 power supply in my van and it's currently only hooked up to the alternator charging the leisure battery. I want to add shore power, do you know if i'd need to add in a charger and transfer switch, as per your example, or is this built into the EC160? Any advice you could offer would be very much appreciated.

[@douggee3610]

Do I need a shut off switch for the battery charger if it’s ran through the transfer switch

[@rosslukeman]

Hi Doug, no you don't have to have a physical cutoff switch for the charger, but you would not be able to turn it off while on grid power if it's hardwired without a switch. If you use that exact charger (IP 22 Victron 30-amp) then you can toggle it off in the Bluetooth app. Hope that helps!

[@DeeJayHouser1]

Does the inverter need to have a true ground, or just a chassis ground, if there is not shore ground?

[@rosslukeman]

Ground it to the chassis.

[@kevindube926]

Is it ok to run wires from a 920AH LiFePO battery bank on my RV to a battery charger on my towed vehicle (lead acid 12 volt) to keep that battery charged for use of the brake controlled and lights?

[@rosslukeman]

Hey there, yes in general that sounds fine so long as you have the proper fusing and cutoff switches, etc. Hope that helps, thanks for tuning in!

[@McRVP]

I'm in the process of building a similar system but I have the Renogy 3,000 watt inverter / charger. Do I still need a transfer switch when using shore power or unplugging from shore power

[@rosslukeman]

Hey there, no your Renogy inverter / charger should have a built-in transfer switch. You've got the right setup, a lot easier than what was shown in this video.
