Hello, can someone in this vlog share with us, where we can download a copy of the 48 volt wiring>

Good morning do the 12v circuit breakers have a connection direction? I have one between my battery and my converter and one between my solar charger and my battery and I'm wondering about the direction of connection... thank you

The 100/50 has a max input of 60 amps at 100v, and output of 50 amps at either 12v or 24v, Hope that helps clear confusion. 50 amps x 14v = 700 watts 50 amps X 28v = 1400 watts Over panel all you want, it will only output so much. But you are 1 increasing the max time with max amps to battery bank, and 2 also placing more stress/ heat on your charge controller in the form of resistance as it will control the charge the battery is getting.

Great Repair Dude !!!

What is the pinout for the hack to make the LED lights work ?

Fabulous test! The graphical display made things super clear. Thanks.

Service port is a great idea

My 12-12/30 charger won’t shut off even with the green plug disconnected what could this be?

Jump the battery with another good battery! No need to tear stuff apart.

Don't use customers eequipment

It’d be more professional if you cover electronics in that unit or do what others suggested use M10 version of the switch.

Perfect this was the video I was looking for

Iv just used metal to secure mine to the roof bars ....do I seem to have a grounding issue or ? So the panel is connected to chassis..maybe I have an earth loop going on ..controller shows volts but never amps ..

How dare you suggest they make it easily Repairable. The CCP would looose their corrupt minds.

Hey Shawn, I'm building (well I guess rebuilding) the inverter setup in my RV, so timely video. Love your work as always. I'm curious, with your neutral wiring on the MP's, did you just double land a small jumper wire between the two neutrals and grounds between the inverters? It was hard to tell from the video. I was going to pull the neutral and grounds together in a couple of polaris taps and run that to each inverter. Six of one, half dozen of another?

18:16 Where can I get a copy of the wiring diagram? Let me know. It's awesome!

Good video.

I have watched all of your build videos. What a powerful and great looking system! What are you designing to charge that awesomely huge 48v battery bank? Can you describe how that is charging going down the road? How are you configuring your solar, 48v+ in? Keep up the fantastic videos!

Getting Amelia to fish that wire may go against child labor laws 😂

Been following the channel for some time and I like the attention to fusing. Have you seen fuses blow? What have been those circumstances?

Wow, super system. We live off-grid in our coach FT with only half of that inverter power. 29.6kwh worth of 48v battery power is fantastic - and affordable too when made from prismatic cells. I did the same thing but a little smaller (23.5kwh), but I have an older coach so was fighting a space/weight limit. Really professional install too - well thought out custom layout. I don't think those batteries will ever get below 30% if you've got enough solar on the roof. Mine don't. My wife gave my tool a name; does that count? I think you need to cut back on that magic smoke some, my friend. BTW, I like to eat frogs - tastes like chicken!

Would it be cheaper to use server rack batteries? Or would it be too much vibration? Thanks Don

Thanks for the update. I have a question that perhaps might be addressed in your next video (or summary video in part 4). Where are the case/equipment grounds from the Victron equipment connected and what gauge wire is it ? Thanks again!

I love the complexity of the layout. Thinking many steps ahead, to come to the proper conclusion. Experience shows.

Awesome! Thanks!!

You can open the 12v 100ah ecoflow battery and the bms is on the top

Another very valuable lesson you have given us. Thank you!

I have a 6 month old Renogy Smart 200A that had issues from new, would get to around 25% to 20% most times then just turn off, you can reboot it by applying voltage, for a second then see via bluetooth one of the cells was low voltage 2.5V other 3 were 2.7V, after some time Renogy refunded the money and I kept the battery, it was a good design because you could simply unscrew it completely, the BMS was on top and everything was accessible, It has 8 cells in 4P/4S, the 2nd set of Parallel cells has lower voltage so I suspect a faulty cell, problem is the cells are laser welded to the busbars so not easy to remove the faulty cell but probably doable with a multitool, other problem is I cannot find cells the same physical size, they are 105A cells but everything I can find is too high, so can't simply put a new cell in there

I hate the way these batteries are not serviceable by simply unscrewing the top cover, it's easy enough to have a rubber / silicon seal in there that keeps them watertight, I understand it makes manufacturing easy but if you have a simple problem like this one you cannot simply reset the BMS, and a normal consumer would end up sending the battery to a recycle yard when it's perfectly ok.

Good video! I have 3 of these batteries. No issues with them. Good info for diagnosing a problem in the future if it arises.

Great job Shawn you saved my 500 dollar battery!!!! Great info for the do it yourself person .

You made a comment about a battery being left all winter without charging, or something to that effect. Way up here in far northern Minnesota, I take my two lithium batteries out of the rv and store them in my heated garage (+/- 40f). Question; can I just use my battery tender, say once a month, to put a little charge into them? Or do we need a charger designed especially for lithium batteries? Keep up the videos, very entertaining and informative.

Thanks for posting and explaining your troubleshooting thoughts. I bought some Battle Born batteries off of marketplace and unfortunately they had water intrusion. So the bottom row of cells were corroded. I replaced the BMS with a cheap Daly version, removed the bad cells and i now have a 75 amp hour battery instead of a boat anchor.

Hive tools are the best for a thin pry bar. Great video. I guess if a person is going to diy a battery repair, getting a battery that is better setup for home repair in the first place, makes it much easier. Like an SOK battery for example.

What does a system link this cost? What is the added weight?

Have the same camper and trying to copy what you’ll have done here. I have the box installed but how did you fabricate the rest? Did you’ll mount another piece a wood above the box?

Have a question on panels. How do the renogy rsp250dct compare to the rich solar 250 watt? Getting new rv the end of April and what to install a 24v system. Thank you, Ken

So then under a mixed battery system like this do you have your charger / solar charger set to lithium ? or Sealed lead acid ? or AGM, ??? I find this video very interesting, Currently now I am running AGM solar Vmax batteries but adding a lithium batter to my system might be interesting.

I LOVE watching all the builds!! Working on my system layout and man, I wish I had the height to use my multi up/down orientation.....But, like you guys, oh well....How thick is the board?

Again great video. Question on the balancer. I have a 24v victron system and I'm using 6 12v lithium batteries paired up to get 3 24 batteries. Ive thought of getting a balancer for my set up. Would it require 1 for each set of batteries or can I reconfigure my wiring to use just one?

Great video. Nothing is wrong with your hair. Looking forward to seeing the next video. Don

Watts are fine. DON'T Over Volt these controllers! They No Likey.

The guide to make the cable is in the distributor manual, so then the real question is, why don't they just add the cable to the product, or make it available on their website..

I love the the table. Marking up the wiring with a sharpie. Great layout.

Saw the Sprinter Van vid today, just wondering when we get Part 2/3/4 of the 48v Airstream ? Thanks!

Nice hair due. You just get out of bed?😂

Question, if lifepo4 battery bank is only charged by solar (mppt) and we parallel that with agm after it's full , would this cause any issue as mppt setting will be on lifepo4?

With the new charge controller inverter your better off in series.

I’ve got one of the 460Ah Epoch batteries and have been very happy with it. Be sure and set all charging sources to 13.9 Absorption and 13.4 float to prevent the batteries from going into “full charge protection”, which happens if the amps are low and the voltage goes over 14. It happens once fully charged and connected to shore power if you use the default Victron charge profile. In full charge protection, they completely turn off, as if the batteries were completely removed, which means they won’t support the 12V loads, and your voltage will fly all over the place since the MultiPlus in float is trying to support the loads. Just a little quirk with the Epoch BMS, but once you know it, you can adjust for it. Downside is Victron makes you buy a $70 dongle just to interface with your PC and make the adjustment, instead of giving you a USB plug right on the unit. You’ll need to adjust the solar charge controllers as well to under 14. Bulk charge will remain over 14 but that’s not an issue since the amps are high.

What are you powering this board with before being placed in the RV?
