Battery is no longer available for sale. For a good replacement AND cheaper, get the Li Time instead.
Li-Time Battery (60ah): amzn.to/3ZzyO00 | It Will fit & Cheaper, but less capacity
Li-Time Battery (100ah): amzn.to/4gePsYj | cannot guarantee fitment inside ToolBox since its a hair larger than the EG4 WP. You could probably modify the box a bit if it doesnt' fit.

In this episode we build a 5 kWh mobile portable rolling solar generator in 15 minutes or less for less than $2000. This portable power station is the Delta pro in Delta ultra killer because of its massive storage capacity and it's massive solar input. This e.g. for hybrid all in one inverter can take 5000 W of solar input and put out 3000 W continuous with up to 6000 W of surge capacity. With enough solar panels you should be able to run this all day. You could run it in your trailer set up for whatever you need it to and you would be good with mounting solar panels on the roof of your trailer. This is a great set up which is portable because it's on wheels and you can wheel it to where ever it needs to go and can easily be recharged by mains power or solar.

Very creative build! It’s a great 120v inverter for the money and the 500VDC charge controller can take in a lot of solar panel power if run in series. I opted to go with a generator cord output that I could connect directly to my generator transfer switch. Worked great! I could run my house loads for 4-6 hours depending on what I used. Keep building! 👍⚡️☀️💡🔋🤠
I'd put inverter other way around so standing up it vents nicely as designed and power strips are higher up...also breaker being down at the ground is going to get bumped, drug thru water etc...that should be up top. Pretty clean compact setup though. I like the MPP 3048 since they work better on smaller arrays that might fit the role of a portable system.
Nice clean setup!
VERY GOOD BUILD,THANKS FOR ALL YOU HAVE DONE.
Great job! I really like how compact it is.
Nice. You just fill your inverter intake was saw dust.
Is the inverter neutral bounded? If so, how you did it?
Can you make a case for the eg4 6000xp and this type of set up. I’m torn between the yellow one and the 6000xp
SAME QUESTION. IS IT WORTH IT TO HAVE 240V
I did this type setup with EG46000XP and 3 lifepower batteries. Its built on a homemade cart 1200lb capacity. goes easy through doorways and easy to roll around and roll on a trailer if needed. The EG46000XP folds down for compact storage. Its recommended the EG46000XP be vertical when in operation.
@@colormaker5070 very cool.. Something I'm going to try over the 3k I think
With that being said I will look for one on refurbished list so yeah hope to get mine all in the water resistance box and some venting
Good stuff! Thanks for sharing.
Could i theoretically connect an rv receptacle rather than the surge outlets? I believe the rv needs 120v 30amp. so is that inverter able to step up your 48v battery and allow 120v output to rv receptacle?
Great form factor, and I like that the battery is inside the box, (which lessens the chance of anything shorting across the battery terminals while working around it). Unfortunately for me, I chose 12 volt, 300 amp/hour batteries, so I'm going to build on a 18" x 40" tool cart, which can hold the 4 batteries on the bottom shelf. The upside of using the WattCycle batteries I chose, is that I get more than 50% more watt hours of battery storage for the money spent, when compared to the EG4 48 volt rack mount batteries, when using four 12V, 300 amp/hour WattCycle batteries, compared to two of the EG4 rack mount batteries. (Well over 15kwh, compared to just over 10kwh)
My question, which I haven't figured out yet, is can two of these EG4 3kw AIO inverters be connected in parallel for 240V split phase operation, AND also be connected to the same battery bank, or must each inverter have its own battery bank? I'd like to build my cart with just one EG4 3kw inverter for now, but add a 2nd inverter later for the 240 split phase power to backup my house during power outages, but my cart won't have room or weight capability to add more batteries. Plus my limited retirement budget doesn't have room to spend another $2k+ on 4 more batteries.
The only problem with this setup that nobody mentions is that if you want to charge this with solar you need to have a minimum of 120V of solar, so if you think you're going to build this and go out camping don't think you'll be able to just plug in a 200 watt portable solar panel.
Right. It it makes it a excellent option for a cheap home backup setup. Even though it's rated at 5000w I think 4000 would be excellent for this unit and you could power essentials for days or permanently with the right batteries.
To generate 120v of solar would take a shizzton of panels to even initiate the mppt charger controller, are you kidding? So that option is pretty much useless unless you have at least 1000 watts of solar panels. In winter you'll need at least 1400 watts of panels. That EG4 system is a joke! There's much better options out there where you don't need that much solar to fire the system up. EG4 get your shizz together!
@@arminius301 That's not true. A typical solar panel is almost 30 volts so 4 in series would produce 120volts.
@@tonyinfinity I was a little off, I stand corrected. My Renogy 100W panels have an optimum operating voltage of 18.6V, so it would require at least 7 of those panels to initiate that EG4 system to even fire up the mppt controller. That's still 7 panels you've got to have, and that's only on a sunny California day at peak conditions. So figure at least 800 to 900 watts of solar. Coming to think of it my math wasn't that far off at all! So I don't stand corrected and stand by what I stated!
@@arminius301 Haha I get what you were saying. Maybe not a "shizzton" of solar but yes you'd need at least 600 watts in series to get the inverter to charge. So this setup isn't ideal for someone going out camping with a 200 watt folding solar panel, but it does have it's uses. If you needed a good amount of power and were just charging it at home off AC power than this would work great. or if you did have 600+ solar array at home, it would charge it, tho it would probably take more than a full day. The EG4 isn't a bad inverter and it would be plenty for a small cabin or RV but this is kind of silly to use on a "suitcase" build.
GOOD EXCEPT FOR TEH DUST IN THE INVERTER PART
i do think just using washers and some extra glue is better then rivnuts
on plastic, you're probably right
Good build but I wish you could have shown how portable it is by moving it on wheels. 🙂
Does the battery get hot in the box? Should I add a fan?
Was thinking the same thing. Vent holes at least
Can you charge it with just a 450 watts solar panel? Or does it have minimum solar panel requirement?
No, you need 120V minimum, so probably 3-4 300-400W solar panels depending on the specific panel's voltage.
Kool quick inexpensive solution!
Great idea nicely done. Do you happen to have the inside dimensions for the Ridgid box? There are 48V 100ah rack mount batteries on sale for Prime day. Could cut the cost down. Again great idea thank you
Love your video, and the main advantage is the solar input definitely. But 9 months later since your video, the Ecoflow PRO is only $2000 (NEW) at Costco.
True, industry is advancing quickly
This unit can far surpass that for the same price right now. You can get a 5000w battery and the eg4 3000 for even a little under.
This is more than double that capacity
Just saw your video, great information and clear instructions. Do you know if you can do pass thru charging with this?
If you configure the inverter to proper mode it can charge and power loads at the time
I just built this system. Can you give me an idea on the settings on your controller?
You are a brilliant guy. Take care.
Thanks!
Great. Very simple. A foldout panel for trickle charge and maybe car battery plug in when driving with a vsr.
Fits perfectly. Does that EG4 unit allow a limited amperage to be pulled from its 120vac input? Eg. If you had a 1500w load and only a 800w generator, or will it just pass the full load to the generator (ac input) and try to load 1500w on to the generator?
The ac charge is setting # 11 Very simple to change so you don’t overload your ac power source. If it’s on a generator you need to keep the load low enough to avoid distortion. If it’s powered by a cord and you’re using the inverter loads ,keep in mind the ampacity of the circuit and cord.
I’ve used this same setup with great results. With a string of ten 60 cell panels and 3 batteries you can take a travel trailer off grid.
I think the lowest ac charge I have used is ten amps,so about 500 watts.
Good design power station
thanks!
The battery doesn't get hot?
Not in my use case. Not drawing enough for long periods of time
The intro... all the sawdust sucked into the eg4 unit. Nice video overall
Will this work with 4 12V 100AH LiFePO4 Lithium Battery's in parallel
Not in parallel. The batteries would need to be in series to reach 48v (assuming the batteries support being in series)
Cool, thanks.
This idea is nothing new except for the thought that went into choosing the right box for the battery. This system is very capable of being the heart of a whole-cabin power supply. All you need are the three or four solar panels that can stand above it to protect it and a way to shed rain. My home system is this simple except for the size. All those combiner boxes are for people who like to spend money so they don't have to unplug a cable. There are cheaper ways to make systems like this if you don't care about having his level of clean fitting. Same goes for making and breaking low-amperage circuits safely and easily.
That box is not vented. Battery will over heat. A hand truck with nematic tires will make a better unit . Less bumpy.
Drill some vent holes. Need a computer fan? $32? Hand truck - cumbersome and bummer when flat or storing. Like the build - use factor.
Technically this is not considered a hybrid inverter, but I get what you are referring to.
dont see a ridgid box with wheels like that. did you custom build the box to add wheels?
I would like to know the dimensions
I bought one like that.
@@2hotscottpro Would you mind sharing the link?
@@ImASurvivorNThriver lookup ridged box with wheels.I guess they are still sold at Home Depot.
I'd be more impressed if you built the battery with your own cells and BMS.

There may be others on the market.
wow very interesting. thanks! so if i double this i get 10kw battery.. and 240w so i can charge my tesla
at 30 amps?
You can only get 12.5 amp out of that box
Covers the whole thing in sawdust lol
My question how the hell do i put the solar panels on a mobile rv or trailer to supply this if they are so big theyre not meant for rv or trailers... anyone have an answer for rv trailer use bc i dont see one beside spending thousands onna heavy duty roof rack to run this in an rv
This would be for a stationary permanent residence with an RV, like having a home base on a small plot of land. It’s really better suited to a small cabin or yurt. Unless you had a schoolie or something very large, Or unless you set up some serious racks and set them up every time you boondock? I mean you would only need 4-5 3-440 Watt panels I think, but definitely not very easy for a smaller van or Rv.
Bruh man. I know you want to show off your unit! Do it away from the dust particles though.
if I watch the Video I only have 2 mins left for the build, shopping for parts, ect 15 mins does not seem very long LOL
Watch while shopping
Sorry but it was like a mechanic opening a hood of a car and telling you have to do this and that and just bolt it together and it's all done.
EG4Electronics looks sketchy to me as they don't have the EG4 WP Waterproof Lithium Battery on their own website and have incomplete tech specs for other products. Who know how much it weigh, EG4 doesn't say. When you are holding that much energy, Thermal Runaway is a huge issue if it starts.
They may be discontinuing the sale of these batteries. There are several other similar batteries and the price is falling. I have two of them. They weigh just over 100 lb each . They have a very good BMS and are LFP chemistry so the fears of fire that were well deserved with NMC are not a problem with this battery.
NOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO
Easier to just get a refurb Delta Pro for $1600. :-)
You get more power ,more satisfaction, at a way cheaper price.
U paid way too much for this thanks tho
So now we're speed racing towards finishing our builds .... less than 5 mins here, under 30 seconds there, 1 minute for this one and 1 minute for that one. All while sacrificing safety on so many levels .... even if you could build this from scratch in 15 minutes or less, you're probably going to end up shortening your life exponentially. This build is about as helter skelter rigged as it can be.
Why,
I'd rather buy a Diesel Generator of 5.5 Kwh for 500!.
Then when you run out of Diesel and you can't get anymore what do you do? Also with this you can live off it, you can't do that with diesel.
@@oswaldmosley6179 Have both :)
The advantage with this over a fuel generator is that with a few panels you can connect it to an essential circuits panel and it starts recovering your investment from day one. If you have its load source setting # 1 on SBU ,that is, solar first,then battery assists when solar isn’t sufficient. Finally,when the battery is discharged to a point you select,it switches to utility in as little as ten milliseconds. Can you start the generator that fast ?
what a load of rubbish refurbished only 100ah for over $1000 must be insane
100 amps at 48 volts. This is a great price! This is 5120 watts. Do your research and you will see this is way better than the pre-built.
Lmao it's 48v not 24v
Cheap Cinese made, lightweight, high frequency, transformerless inverter chargers like these offer a far shorter life expectancy than far more reliable, heavy duty low frequency, transformer based inverter chargers. High frequency inverters like these also offer a far poorer surge capacity than low frequency inverters when it comes to starting inductive more loads.
You write this on every video. Get a life?
Hater
Ok one of the most dominant names in solar right now is trash and only you think that....
Are you kidding me? This is DANGEROUS. You are being irresponsible. DO NOT DO THIS based on THIS VIDEO. If anyone gets hurt by following this video, it's THIS GUYS FAULT. DO NOT attempt this unless you know what you are doing.
People build these every day, are you crazy!
??? What part is dangerous?
@meilyn22 inverter should be in upright position when running
Can you elaborate more??
One could get electrocuted or blow things up. Also it could be dangerous for others and cause fire etc.
