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!

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.

As a mechanic, for 20 years. Then a commercial electrician, it kills me that just about every KZfaq influencer hooks up battery's backwards. Remove Negative first, and install Negative last. That way you have no chance for that spark, or an explosion in your face. No resistor needed. I have seen so batteries explode, and injured people. Yes from lifpo-4!!

You're always so good at thoroughly explaining everything! And making it look so simple. Thank you, Jason.

I'm just getting started in my solar journey and I am looking for informative videos. I like your presentation style. It moves fast, covers the subject well. I appreciate the matter of fact approach. You speak clearly without stammering or pauses. I subscribed and liked. Well done.

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.

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.

Thanks! Hi - I wanted to thank you for all your help. Thanks for being a team builder! I have learned a lot and it has saved me a lot of grief and dollars!

Love the setup, definitely a life saver for any emergency...well explained great channel....!!!

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

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!!

Awesome video

Great build on the modular setup. Power stations are great but these can be fixed or parts swapped and more. Great for the person who likes to build there own..👍🏼 The sparks 🧨 were great to 😅😉

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.

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

Hi Jason, I really love your canned food setup in the back. Looks like it's setup so you can see the dates on all the cans.

This is a fantastic video. The info you presented was just outstanding. Very good learning

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

Very informative. The fan noise would quite down if you hung the unit on the end opposite the handle thus having top to bottom airflow. That would also free up the top shelf.

This is one of my favorite diy build videos. Well done, thank you. I'm jealous of all your backups btw. Subscribed, bell rung, commented, upvoted, liked, shared ... may the algorithm gods smile favorably upon your channel friend.

Excellent thanks Jason 💐

Excellent video. Great information.

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.

Excellent video as usual!

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!

Nice informative video. Thanks for sharing and giving us lots of details on this.

What up Doe!? I really like that all in one setup with adding 4 batteries Dr J' 👍🏻👍🏻

Great video, I just made a video with my slightly upgraded setup, still 12V... i want to go 48V soon. your video helped explain some of the aspects of it. thanks!

Very nice! Thank You!

Awesome video. I wish I seen it sooner. I’m now to far into my 12v system to make the switch. No pun intended.

I used that same cart for a build I did about 4 years ago using Tesla modules. 👍

Thank you! 5ohm 10 watt resitor those huge sparks are always adrenaline dumps😊

I love the Rack to the Right with the Preps. I see your Prepared. I have a similar setup myself

I think it's totally awesome!

You are a great teacher....

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.

Great Video Thanks Jasonoid!!

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.

Excellent video. I have a Delta mini but I think I will build one of these also because I can always add additional batteries later on.

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. I'm looking to do this with a 5kw 240v hybrid growatt to power my house as I'm exporting 20kw a day back to the grid yet still have to but power everyday .

Great video!! Awesome idea! I am going to copy your system. Thanks for sharing your build!!

Nice one bro

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.

awesome build👍

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

Good stuff 👍

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.)

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.

Looks like the one silver Stacks Prepper made. Nice 🙂

Thank you once again. 👍🐝🌞

all in ones are for sure the way to go when it comes to solar input and battery storage cost if you dont need to be mobile.

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.

Don't solder your wires. It may seem like a good idea, but due thermal cycling, it can loosen. Best practice is to crimp.

Great video on "Energy"! As an outdoor enthusiast and RV lover, I highly recommend checking out the Segway Portable PowerStation Cube Series. With its massive capacity, fast recharging, and waterproof technology, it's perfect for powering all your devices and appliances during camping trips or in case of a power outage. Plus, the Smart APP Control feature adds convenience and peace of mind. Definitely worth considering for your outdoor adventures!

Great video and I've done a similar setup with a cart in my garage so I can bring power where I need it in my driveway. If I would do it over again, 48v all the way.

I happened to be watching while on Bluetooth to my home theater receiver with Klipsch dual 12 sub. When you connected the battery to the inverter, the floor shook🎉 😂

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

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.

NICE!!!!

Awesome!!

Oh, one more thing...I create insulated sleeves with heat shrink tubing. I tape off one end with electrical tape and then I slip one each over the pos and the neg lug. I use a tubing diameter that is snug enough that it will not fall off.

One thing I would be a little weary of though is tinning wires before putting them in a compression style connection like that. Probably will be fine though. Nice video!!

👍👍 good vid, thanks.

Always check your regulations. Where I live they won't even allow a 1000w system in your home. That's just a single 12v 100ah battery! I can however stick it in the detached cold garage....

Thanks!

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.

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

Enjoyed your presentation and certainly a modular, DIY approach to home backup power is in many ways superior to off the shelf products. I forget, was there a monitor for battery SOC in your set up? For camping (and home backup), I built a 12 V 100 ah battery with MPPT charging, various connectors, a charger and a small inverter and find that an EcoFlow Delta 2 does the job better in a smaller package. However, if anything goes bad on the Delta I can’t really know what has gone wrong and will have to wait weeks sending it in for repairs, etc . With a DIY unit, you have more options. Did I mention I really enjoy your videos?

Older video I know, but... Could I tie two of these inverters together for split phase 240? I understand this can get complicated... Just wondering if this inverter can do that or if you have a suggestion on a different one to accomplish the goal of a similar cart build but that can provide 240 (split phase). Thanks for the video and simple break down.

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

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.

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

This is great. I was just talking to Ask Ive Solar about a very similar setup as an alternative to a powerstation. Though it was using an EG4 version of this and server rack batteries. Did you consider the structural foam carts? They are the same though they might not have the middle shelf. I like that a system based on an all in one tends to have a lot more charging amps, wider voltage range, and programmability. I am trying to figure out home assistant right now so I can make my EG4s turn on AC charging when the forecast and my weather station confirm poor sunlight.

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).

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

Great video and I love the cart idea! What would you say are the main advantages over this system vs a Delta Pro? I know what the retail price of the DP is but they routinely go on sale for close to this systems price.

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

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.

I've got the same system, except for the batteries. I have two 300 ah 12v power queen batteries. The same sungold 24 volt system. Will see how it works.

great video thanks. Is the AC charging input variable ? Can you adjust it to charge from a 1000w external generator?

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 ?

Great video! I just recently found your channel and have really enjoyed your clear and concise presentation. I am really considering this sungold inverter. Quick question- how big of a battery bank can this take (e.g how many amp hours)? Thanks!

Nice.

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

Really great video! Very helpful!

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

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 .

💘💘💘💘💘💘. Love your presentation. Thanks

Great video Jason, I'm thinking on two of the 12.8v 200 amp batteries. What would you say?

I just installed a whole house 26kw NG generator with ATS and am interested in adding a whole house battery pack to sustain for 3-5 days. When batteries are exhausted generator starts, recharges and then shuts off. How do I determine my battery needs for whole house application?

Hi, thanks for the video. Do the Power Queen batteries have low temp charging protection?

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 KZfaq and catch up with news and social media. Good thing I have a ULP genset as a backup I guess.

How would this set up compare to a Eco Flow Delta 2 Max? I think it has more storage capacity? Trying to figure out which way to go for a home backup system I would appreciate any help

What is the durability of this set up? How often would you need to replace things like the batterys and inverter? I mostly want something like this that i can use as a power source during emergencies so i don't have to run my generator all day and night.

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

pro tip - never use a metal cart. plastic/resin carts are cheaper, won't ever rust, and avoids any issues with electrical devices

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.

Hi Can you charge from ac and same time use transfer switch like UPS for your fridge or pc , great video thanks

There was no comment about the transfer switch wiring, normally they are wired for 240 split phase, but your invertor was 125V...I know the teansfer switch can be wirred as you want, but I did not hear that mentioned.
