[@drewtedeschi2219]

Very great build Quick background, im a marine electrician, and design and install systems on boats like these One thing i would recommend is using a class t fuse for the inverter We’ve seen anls break and then re-weld themselves back together and cause a fire But beautiful system!!

[@Jasonoid]

Thanks for sharing your experience, that's helpful!

[@barntt]

NICE! Rule #1 Nothing is EASY! Some suggestions for safety IMHO to prevent a fire (these things HAVE caught Fire). HEY! it's YOUR home. Think AC panels here. A Main disconnect switch of the proper size at the source (that big battery is the source here). THEN a fuse or breaker of the proper size to carry your load and protect the WIRING within 7 inches of the battery POS post (REQUIRED on a commercial unit I believe). Do maintenance checks often and keep connections clean and TIGHT. Could it pass an inspection? HEY! WHAT CAN GO WRONG? Insurance have disallowed claims because of these things. Do it RIGHT don't just make it work!

[@winstonsmiths2449]

I built a system very similar to yours but I used a cart made of composite material that is non-conductive. I enclosed the battery storage shelves with chalkboard material bought at Home Depot for under $10 each. I cut them to cover the sides and back of the open areas pf the cart. I secured them to the cart with strong Velcro. This will prevent items getting into the battery area. I do not have insulated tools, but I do cover the tools I am working with in heat shrink tubing.

The only thing I would change with this system is placing the battery fuse closer to the battery and adding a battery disconnect for safety

[@OUFan2]

Very good video. I built a 12 volt system like this about 2 years ago using a cart from Harbor Freight. Makes it nice to be able to just roll around the diy solar power station.

[@brucebugbee6604]

Nice project and well done video. I really like the concept. Since I already had a 24 V home backup system using rack mounted batteries and Victron Multipluses in split phase mode, I didn't need the inverter. So I just built a 24V battery bank on a three tier cart using 2S3P x 12V 230AH TimeUSB batteries which provide an additional 17.6 kWh of battery capacity for about $3,000 including the cart, bus bars, breakers and cabling. I plug it into my system using 2x175A anderson connectors and 2 x #2AWG cabling.. It works great and has become a permanent part of my home backup system. One additional item to consider when putting 12V batteries in series is to make sure the batteries are all top balanced before hooking them up and add a battery equalizer to keep the 12V batteries balanced over time.

I own two Bluetti AC200P's, Echoflow Pro, and an off-brand 2000 watt solar generator plus I have 2820 watts of solar input. My solar generators are usually fully charge by around 12:30 pm. I live in Golden Valley, AZ with around 300 full solar days per year. I have excess solar charging capacity on most days. I like to tinker around with stuff. So, this gives me some ideas for my next project. Thanks for the video!

[@BenEehayeh]

The Danfoss BD50f compressor, for refridgeration, can operate in any power source, it requires 109 watts to operate. You need to purchase the Power Module for your voltage needs, 12/24v, 115v, or 220v. The Power Modules contain an inverter, transforming the input voltage to the requirements of the BD50f. If you have a 115v refridgerator with a BD50f compressor, you can swap Power Modules to the 12v version and run the refridgerator directly from batteries without an inverter. Therefore, more efficient battery usage.

[@genetownsend8847]

That is good to know!

[@Ausprep]

Cool idea, however your fuse amp rating needs to be smaller then the amp rating of the cable. Also solder on cable going under a screw isn't good practice. But well done and good work.

[@DanielSan-ch7dr]

Stand your inverter up cause heat rises and it rising up into the electronics whilst laying on it back. Great idea and I love that you didn't hide the prices like most people do.

wow.. thanks for the tip about the resistor.. really appreciate it.

[@saeedhossain6099]

love the cart setup. an alternative to the resistor is to put a filament light bulb in series on the positive lead when connecting the battery. also there are a lot of 240vac output ups solar inverter chargers. to use one of those you'll have to add a split phase or center tap transformer, but you can get from the ac output lower amperage while delivering the same amount of power.

[@Ulbre]

What a great tutorial and super neat build. Really interested in that transfer switch and glad to see you also have a video on that. Will be watching that next. :) Cheers from Chiang Mai, Thailand.

[@shelley131]

Thanks for your video, great as always. Wondering if you could do one explaining the pros and cons of 12V vs 24V vs 48 and break down where it would be most beneficial.

[@Jasonoid]

Great suggestion!

[@equanimousawareness]

48 volt is more efficient than 12 or 24. The more voltage step-up the more power is used just for the step-up process. When using a 220 split phase inverter to power central AC unit or other 220 appliances a 48 volt system is pretty much a must.

[@robertsmith2956]

@@equanimousawareness If all your doing is keeping the fridge running, 12 or 24 volt is better since the inverter doesn't eat as much power sitting around waiting till it needs some energy output. The 48V split phase eats more power if the AC doesn't turn on.

[@maxamps45]

I like the thinking outside the box. We have come to be reliant on plug and play, if a single device i.e. solar generator fails, or your generator fails, you are SOL, this has its place. Single items can be replaced to restore the system. Having said that, I am a huge bluetti fan, I have AC200max with 2 b230 batteries. I have 2 EB70 and 1 EB55 in 220v versions. I have spare cables and spare power supplies. But always looking for other ideas. Great video thank you.

My setup I made in 2016 uses 4 6v 260Ah AGM batteries (Renogy) due to costs of lithium in 2018. A Renogy 2000w pure sine wave inverter/charger, cables, breakers, and fused properly. An Epever 40amp solar controller, MT50 monitor on an 800lb Gorilla cart. I can grid power, generator, or use the 800watts of solar panels. Tested and routinely used as UPS.

[@Jasonoid]

Great setup! That's a lot of power right there!

[@fastereddieb]

Nicely done! Is there any reason not to use a 24v lithium iron battery of appropriate amp/hours? Seems like it would reduce a bit of wiring.

[@Jasonoid]

Yep, that would work fine as well. Jus make sure the BMS can handle the max load of the inverter.

[@fastereddieb]

@@Jasonoid Thank you. I was impressed with your setup. Mine is far simpler for now: A Goal Zero Yeti 1000 Core that I’d like to “expand” to power one refrigerator and a TV/Starlink setup in power failures, and to use in our camper to extend boondocking time. A 100A/H 24v battery would preclude the use of a DD to DC converter - my model requires at least 14v at the HPP port to take a charge. And a single 24v 45 lb battery would be handier than 2 25 lb 12v batteries wired in series. But you’ve given me ideas for future projects!

I’ve watched dang near every video I can on this, definitely good info. Might do a combination of the two. Buy a complete system that’s made to match properly, and build it into a portable system. And I do want the ability to plug it in with past through charging capabilities where I can plug into the house or a generator if needs be. I will probably use one of those ABS carts though. I see you guys all using these metal ones and it make me cringe 😬 because I will will shock the hell outta myself doing this otherwise 😂🤣😅

[@johnboy8211]

Seeing that you are going to a transfer switch, do you have the neutrals from invertor , line and load tied together. Bonding of neutral and ground at main line panel only. So your inverter should be a floating neutral , not bonded. The rule being bonding can only at one place only .

This video was great. Cool project, but I would argue the summer vs winter fridge thing depends…. We keep the house colder in the summer than we do in the winter. The fridge operates on ambient temp, it exists inside the conditioned space of the home, so my assumption is that my fridge uses more power in the winter in my home.

[@davebacknolaliki1452]

Is it possible to build this inside a big tool box? I just sold my small power station because i want something bigger for emergency or my job ( drywall construction) and building this on a tool box would be easier for me to carry

[@pilinke11]

@Jasonoid thanks for taking the time to answer!! I also saw a new power station dabbsson for a great price. I'm looking for a good 2000wh power station but I'm not sure if I should build my own because of all those bad reviews about costumer service also saw oukitel p2001 for $950

@@pilinke11 I'm doing a really simple backup system video using a 12v 200ah battery and a 2000w inverter this week (should be out Friday). It's been running my fridge for 30 hours so far. DIY is nice since you can swap a part thag fails vs having an entire system go down. I have more confidence in the higher quality power stations but you have to pay a premium for them so DIY is a bit cheaper.

@Jasonoid I will wait for your video on Friday I need a backup but portability and the diy way is great in case something happens 😀

[@graphguy]

This was great! It proves to me (sorry solar off grid geeks) that it is not cost effective for me. We live in a very mild 365 days a year area with it being rare to very rare to have bad weather nocking our power out... so there is really not a need there. I do have a gas generator, but that is really just used to power tools/equipment when away from AC. Spending $2,000 to have off grid power in my home is just not cost effective. I would never die to not having power and if I loose refrigerator worth of food -$300 then so be it as that is a 1 in 100,000 possibility. Now don't get me wrong as we are gong to build a second house off grid and at that point I will plop down $50K to get solar power.

Question so the power coming out of your inverter is only supplying 120 volts to you transfer switch am I right. If not how did you wire the the connection in the transfer switch box. Why didn't you ground the output from the inverter. Thanks

[@jonphanspromotions]

do the AC in and out need to have breakers?

[@infunerous666]

It’s a floating neutral device, which is good because it will ground to your house via transfer switch. You don’t want 2 ground points at once

[@ModaAli96]

Can you connect the ac output to the wall plug to run all the house power And also connect the ac input to wall outlet to charge the battery when the power come at the same time ?

I was wondering how you wired your transfer switch. The inverter output is 120V AC. So you can't wire with 120/240 split phase. Did you just use a jumper off the hot to power both bus bars with 120V? Seems like that is the only way be able to use all six breakers. Thanks.

[@Jasonoid]

It's a 120v transfer switch. All circuits are powered by one 120v leg. If it was a 240v it would require two hot legs. They offer many different models.

[@ronbridegroom8428]

Can you use circuits from both 120 volt legs of your house 240v system or is a Transfer Switch limited to just one leg?

[@Jasonoid]

You can have both 120v and 240v transfer switches. You can connect to either leg. I have circuits from both sides. Reliance Controls has some really great videos on them on KZbin.

I bought the 24v kit. The issue I have run into is delayed shipping. They didn't inform me most of the kit is in background. The other issue I ran into is I did manage to get it put together and the batteries won't charge. Tech support is really slow to respond.

I really need to upgrade my system to LiFePO4 batteries. I've got a similar setup attached to 2 160W solar panels. Two 115A/h AGMs, a controller/regulator, and a 3000W Pure Sine wave inverter. I feel like it needs more battery capacity because I can lose 10% of my charge in an hour or two in full sun on the two parallel-connected batteries when running a computer, TV, stereo system, a 75 litre dual zone twin-lid camp fridge, a phone charger, and some LED strip lights. I'm wondering if I've set up an inefficient system. Both panels are connected in parallel as well. Maybe I'm expecting too much from the setup, I dunno. I can run the fridge by itself overnight after an hour or two of using the computer system setup, and it only drops to 48/50% . I need to rethink my computer setup though. It's a desktop using a 100cm Tv as a monitor, and a Sony stereo system for speakers. A lot of power just to watch KZbin and catch up with news and social media.

Standing up the inverter will allow maximum cooling. If the fans on the bottom are sucking air in and the vents are on top, having the unit upright will keep the unit cooler via the chimney effect (heat rises).

It actually pulls air in from the sides and shoots it out the bottom. The fans really move the air so I don't think it laying flat is an issue at all. The air coming out is always cool.

I bought a 20 amp plug in charger for my big 300ah battery and I used it with a 2000 watt inverter to power my microwave during a power outage. It was also nice to know I have multiple sources of power when the freezing storm with high winds hit n December, especially for my electric blanket. The wind chill was below zero and the power kept failing. Of course the new electric blankets are digital and so are the heaters I had here, so they don`t turn back on when the power goes out for a few minutes. So I plugged my electric blanket into one of my Bluetti EB70s. I accidentally put it on medium high instead of a lower setting when my foot hit the control switch but only used about half the battery during the night and of course it stayed on. I ran my WIFI and lights from batteries too. My 600 watt manual heater was at my sister`s house since it`s "too cheap" (I`m so dumb, see) so my nephew refused to bring it. I had to use the horrible and way overpriced digital job that`s 1500 watts and is either too hot or too cold and has to be turned on and off every few minutes and turns off when the power fails. It would drain my battery in a couple hours. So more and more I appreciate having these backup batteries and even have seven various low wattage cookers now that work with them. Six of my cookers work fine with my 500 watt power stations too, and two can be used with some of the smaller ones. I was born in the mid 1960s so these things are like miracles to me and I will never stop being amazed by this technology.

[@Jasonoid]

Glad your backup batteries and inverter are working well for you! Have you built up any solar charging yet?

[@baneverything5580]

@@Jasonoid No. I`m ordering another 190w HQST panel next month and the bolts to connect the 200 amp fuse to the inverter cable and some switches to be able to disconnect the panels and battery. After that I`m getting one more 100w panel to have four of those in series/parallel with the two 190w ones. Later I`ll either get two more larger panels or two 100w ones. I`d prefer the larger ones but the cost is higher. I need to get two 100w mono panels. My others are poly but the 190w ones will both be mono. The good thing is in a pinch I can dump power into the large battery with my two EB70s and my two 500 watt power stations with the 20 amp plug in charger. I need to learn how to do this with their 12v ports but they only produce about 100 watts. I`m thinking of getting some cheap MPPT charge controllers to rig up for this. Not sure how to go about it yet though. It would be nice to have that option if needed. I can dump over 1500 kwh into it that way to extend run time. But I also want to be able to get the big battery back up from a very low state of charge at night or on a cloudy day if I happen to drain it too low. I think the higher priced Renogy 500 amp battery meter will prevent that. There`s a less expensive one but it may be more difficult to use and may not be worth the 20 bucks less. I want an accurate meter to avoid surprises.

Thanks for sharing the cart build, i think you have enough room on that shelf for 4 of those 200ah batteries so a 48v system coulda been done i think. i was a bit concerned seeing that battery not in a case, but then ya told us its because it wouldn't fit on the cart, still looks a bit weird but, it works.

[@Jasonoid]

Even though the battery was removed from it's case the terminals were protected. One could fit 4 200ah batteries on the cart if two of them were removed from their cases, sad to see so much wasted space on these larger batteries! That's why I recommended the four (100ah) batteries in a series / parallel config so the battery warranties would be intact still. What I need to figure out is if a 48v server rack battery would fit on the shelf of this cart...haha

[@user--PM]

i am sure you have watched some of will prowse's videos and that will give you an idea of how large those server rack batteries are. i would think that not gonna happen. a cart video of another creator i watch kzbin.info/www/bejne/gGq6i5aDebaUesk

[@Jasonoid]

@@user--PM I watch both lithium solar and will prowse videos 👍 I love that cart video! Excellent design!

[@shawnthomas6460]

Thank you for sharing. I am looking forward in creating my own system.

[@Scat.original]

Do you have a link to the Oscilloscope? Great video Thanks

[@Jasonoid]

Here's a link to the same oscilloscope: amzn.to/4bCqqRp

[@RamonIntriago-x2p]

Can you add a wind generator with that system

[@nevv8581]

Another great job and video. Thank you for taking the time and sharing the info. God Bless.

[@OzSteve]

Any chance you could do a current remake since prices are cheaper. I'm looking at doing this for an emergency system (with Victron items) Love the videos as always

[@czexybeast]

Great video! Was looking to something similar l but with the MPP 2724, but I can see the versatility of using a system that plugs directly into a transfer switch.

[@Jasonoid]

With a system like this you can take it with you to the next house :)

[@Sylvan_dB]

Wow, this is almost what I'm working on in my basement! I saw Survival Lily use a cart in a video a while ago, which I thought was a wonderful idea, and now you. 😁For what its worth, on mine I am using 4x 100Ah batteries that just fit on the bottom shelf. (I used a piece of 1in thick insulation board under the batteries to cover the screw heads for the casters and the ends of the screws holding the uprights.)

[@Jasonoid]

Four 100ah batteries is probably the best way to go, then you can pull the full 3000 watts.

[@joevaldez2571]

Im doing the same setup but my transfer switch has a L14-30P plug. How do i wire this? Do i put thr two Hots together or only use one? Luckily im not running anything that requires 240 on my transfer circuits. So the 110 is fine.

[@Jasonoid]

If you are running only 120v circuits, you can purchase an adapter that's 'bridged' between both 120v legs so it will power both sides of your transfer switch. Most dog bone adapters are bridged

[@joevaldez2571]

@Jasonoid Thanks, I already had a spare L14-30P cord. So, I spliced the X-Y together with a connector and Ran a single wire into the L slot and the Neutral in the N slot. I also went ahead and ran the Ground to a nut on the back of the unit. Does this sound all good?

[@Jasonoid]

@joevaldez2571 it's hard for me to tell from just the text here. You'll just have to test it out and see how it works.

[@DeFiDuke]

hi i want to use this diy technique to power my rv using the 50amp plug that I usually plug into the camp site power pole.. is this possible? similar to the new power banks that can do that example: oupes mega 2 , 3 and 5 .. thanks

[@Jasonoid]

You'd just need to connect an adapter thats compatible with your connection. I don't see why it wouldn't work.

[@kevinholland4156]

I've always liked the component systems. I guess this is a hybrid component system. I am impressed. Are you going to put the add-on WiFi connection on it? Great concept of the HF cart. Thank you for a very good video Jason.

[@Jasonoid]

Thanks Kevin! I like how it has the option for the WiFi module and I have thought about adding that for convenience. I'm just hoping this project is an idea bed for others looking to do the same thing.

[@tumbleweed1976]

Excellent ideas. Nice to DIY and have a purchased solar unit. Caution with the metal cart 💥

[@Jasonoid]

Short circuit = BOOM! haha

[@jamesdiggs6742]

How would this be using in a van?

[@justin6125]

do you know of any software for the communication that will work for this inverter. i built the same sort of setup

[@pauloconnell7668]

Tear downs are good. You really do need to see the quality of the build.

[@sophiafunworldatthepark6740]

Do you think the DIY vs. the dabbsson 3030wh (DBS1300+DBS1700) that is just $850?

[@byzantinelegionnaire9469]

@Jasonoid how would you set this up if the house already has Solar but no batterey system for the house?

[@Jasonoid]

Usually grid tie systems do not support battery connections or if they do they have to be a proprietary setup. That's the one downside of those systems. I use this setup with a transfer switch which is completely separate from the grid when in use.

[@mobius6772]

I live in SW Florida and the last hurricane I was in power was out for 11 days. With a few solar panels would this system power a small in window roll around AC unit and the fridge and freezer? and how many solar panels would I need to get to recharge in timely manner?

[@Jasonoid]

This setup would power your fridge and freezer just fine. I'd recommend around 400 to 500 watts of solar for the setup in the video. If you wanted to power a window AC unit you'd want a larger battery and double the solar.

[@mobius6772]

@@Jasonoid thanks Jason, would love a video simulated 4-5 days of power outage and what essentials you could power. There are like none of them on youtube that I could find. Most of it is peace of mind, food storage and the ability to sleep comfortably at night.

[@Jasonoid]

@@mobius6772 I have a wife and kids so a long term simulated power outage is pretty hard to do with all the requirements of normal life. If it was just me at home, totally! I am currently running my Ecoflow Delta Ultra with a reliance controls 10 circuit transfer switch and it's powering critical loads non stop. That test has been going for about 1.5 months now running 10 circuits. This setup does require a bit of solar and batteries but it's possible. I have about 20kwh of batteries and 2400 watts of solar. I see a constant load of about 500 watts. During the day it's no problem when the sun is shining. It's getting through the night and cloudy days that's difficult.

[@mobius6772]

@@Jasonoid Sorry Jason I was a little vague, I was just interested in a setup that could run a inside (Fridge Freezer Combo) a (garage stand up freezer), and (a roll around AC unit) to sleep at night. All of this that could be recharged the next day from portable solar panels if it was a sunny day. I am new to solar and battery system so forgive my ignorance. These are all for emergencies to go 5-10 days without power.

[@Jasonoid]

@@mobius6772 I got lots of videos showing options that will work for you. An air conditioner is a large power consuming device so just be aware of that. One thing you could do is purchase a watt meter and track how many kilowatt hours each device pulls for 24 hours.

[@linkinanytime]

Love this setup. Would you consider doing remote consulting for a fee to help me on a similar setup?
