- I have always been interested in solar and battery power and now I have finally had the opportunity to build a solar generator or solar power station completely from scratch in a completely DIY style. I will show you the components I chose, explain why I chose them and then show you exactly how I built this portable solar cart step by step. I'm surprised how capable this is, especially compared to prebuilt power station (like EcoFlow). This set up is capable of 3000KW continuous output and can store over 5kWh of energy in the battery. I went with EG4 components for the simple reason of great specs for a great price. The battery I chose is EG4 LifePower4 Lithium Battery | 48V 100AH | Server Rack Battery which is UL certified and the inverter is EG4 3kW Off-Grid Inverter | 3000EHV-48 | 3000W Output | 5000W PV Input | 500 VOC Input. Both work in tandem and establish communication making it an easy set up. These are also stackable and capable of MUCH bigger loads and storage limits. In fact, I plan on adding another inverter that will double my output as well as input and power my BMW i3 (EV) as well as half of my house!
Total Cost:
Inverter: $700
Battery: $1200
Hand Cart: $30 www.harborfreight.com/150-lb-... LifePower4
PowerStrip: $20
Connectors and Crimper Tool Kit: $30 amzn.to/3yOg2qZ
Some Spare Wire and the rest: ~$20
Total: $2000 (tax included)
Comparison to EcoFlow Ready To Go Solutions:
EcoFlow DELTA Pro Portable Power Station: $2600+tax
amzn.to/3Xa8Lfk (affiliate link)
-ONLY 3.6kWh of Storage (compared to 5.1kWh)
-3600W Output (compared to 3000W)
-ONLY 1600w Solar Input!! (compared to 5000W)
Next cheapest option seems to be the Delta 2 Max, which is on sale for $1200+tax right now:
EcoFlow DELTA 2 Max Portable Power Station: $1200+tax
amzn.to/45hdMEQ (affiliate link)
-ONLY 2kWh (compared to 5.1kWh)
-Only 2400W Output (compared to 3000kWh)
-ONLY 800W charging (compared to 5000W)
Above, but with extra battery:
ECOFLOW Portable Power Station DELTA Max 2000 with Extra Battery: $2200 +tax
amzn.to/3Vts3Lp (affiliate link)
-ONLY 4kWh (compared to 5.1kWh)
-Only 2400W Output (compared to 3000kWh)
-ONLY 800W charging (compared to 5000W)
It would be more comparable if you get a second battery to go with this set up, but that’s an extra $1000 and you would still have 20% less storage!
Don’t get me wrong, these are awesome and a very elegant all in one set up, but when it comes to value for money, it’s not even close!

Thanks for going through the inverter settings. I was really curious for that!
Glad it was helpful! Thanks for watching.
Very cool! Nice job!
By far the best and cost effective components on the market right now for this or any offgrid power, very good explanation on the configuration and set up.
Couldn't agree more, it’s such an accessible system for DIYers and those new to solar and power banks etc. thanks for watching!
What an awesome video, I never knew I needed this!
Thanks for watching!
Great video. IM going to built now
great overview ❤
Nice project!
NIce setup! I noticed your Illinois Plates, I live in Chicago and also have a BMW i3, nice to see i3 owners here. Thanks for sharing!
Ive expanded it further now and its amazing! Thanks for watching and yes, there are DOZENS of us here!
Good video…
Gives me an idea.. I have a just converted an ICE mini pickup. A 5kW + 5kwh inverter/battery is planned and this video just came at the right time. Thanks for up loading..
Oh BTW, I have a cheapo hand cart laying somewhere in the garage.
aawesome and compact..........and POWERFUL............yelp I WANT ONE.....A good project 4 me
IVE TOOK A year of electrical..and wired up some apartments...an houses..so this project is right for me..
Thanks for the demo and tips. Super helpful, especially with programming the inverter.
Are you going to leave both greens into the ground?
Awesome build. Beautifully simple. I might be tempted to upscale to taller cart and up to 6500 EX or similar to get 240v/ faster charging.
Great idea! Post your results if you build one. Thanks for watching.
Also, you would get faster charging if you had bigger panels and more panels. You don't necessarily need to go to 240v. This inverter can output 3k Watts......
I have since added panels and wired up a 15amp charger, so charging at 1.83kW for about 8 hours from the sun! More than enough to cover my commute!
Where did you buy the battery and inverter from as well as the solar panels.
What size solar panels are you using 🤔.
Thank you for the information and the awesome video.
nice project ..
actuallly charging your EV directly from the sun and storing it in a battery that is complexly portable, WOW...I would like to build something like this for my EV, good thing too is that I can also charge the battery on my eBike as well brilliant....
just one question: as I live in Australia could I buy the EG4 in Australia or where would I buy it from, and would they ship to Australia....thanks again for the video
I've been using it to charge my eBike as well and now powering a mini split also. I've added a few panels and it's powering everything without any issues!
As far as shipping to Australia, I have no idea.. I imagine you guys have other brands with similar set up there that would do the job just as well.
What if its a cloudy day how does it preform ❤❤
A nice little system, however it’s a little small to effectively charge the i3 fully. Are you planning to scale this up?
I added a bunch more panels and wired up a 15amp charger. Now it charges at 1.85kW. So, it takes 10 hours from 0-100. I drive around 15-20 miles a day, so this system fully recharges the car each day for me, unless it’s raining.
Can you do 2 of them sitting next to each other and get 240v for ev charging?
Yes, you can. In fact, that’s exactly what I’m doing at the moment!
@@SimpleCarGuy but how you going to be like hooking up together? 🤔
Wouldn’t it be better to use a breaker box for the solar input for connecting and disconnecting them? Also, is there an app that you can use to adjust the settings? Thanks
Eg4 has a Wi-Fi dongle and app you can use.
What solar panels do you suggest? You said those were portable 300 watts.
Anything you can find for cheap that will have enough voltage. I got 15 of these for $50 a piece and I’m building up a much bigger system with them.
You need minimum 120 volts from the panels to start this inverter. These produce about 40 volts so I put 4 of them in series for the test and demonstration. If you can find some 500w panels for like $100/each, 3-4 of those would give you 1.5-2kw of solar at peek sun.
There is some math involved here and Will Prause just did a great video on this topic, so check it out.
@@SimpleCarGuy thanks for sharing this start idea for charging EV and I subscribed. As you mentioned this inverter has 3000 watts out and 5000 watts fro PV Max. Just curious, if I have 5k watt PV, but only able to use 3k watts. Seems like I didn't use my max PV or other words, I lost 2000 watts. Should I buy solar panel for 3k or 5k watts to work best with this EG4 Inverter? Again, thanks for sharing and please post more.
Is there a way with that all in one to take in power from a 12v dc source like an RV alternator?
I take it that all in one does not support communications with the battery (I did not see you plug in communications wiring)?
You would have to use a step down converter. Will Prowse CZcams channel has this build with 12v converter attached to the battery.
You can use a 12v dc inverter that ya plug in to a cigarette lighter to charge....but it would be a really really long time and you would not get more than 5 amps of 120v AC off that inverter from the lighter socket....I would just say overall....not worth destroying your RV alternator....not designed for that.
Hi. Curious if the outlets and usb are for 48v appliances? Would my computer fry if I plug it in to the outlet? I figured I would need some 48V to 12V down converter?
I think I just realized why my question. The 48V is converted to DC and will run most appliances on DC until.3000W are taken?
There is no need for a "48V to 12V down converter." The storage battery is 48V DC (Direct Current). The inverter (the yellow box) makes that 48V from the batteries into 110V AC (normal household power - just like the power outlets in your house). As such, you can plug anything into the power strip (he has a power strip hard wired into the yellow box) as long as it is not over 3000 watts total.
Keep in mind that power strip is most likely only rated for 13 amps (or about 1500 watts total). Therefore, even though his inverter is capable of putting out 3000 watts continuous, his power strip is limiting the output to 1500 watts. That is why he hard wired a second NEMA 5-15 plug into the inverter so he could use the car charger without overloading his cheap power strip.
Bottom line, any normal item you could plug into your houses wall power outlets, you can plug into this system. Of course, everything plugged in can not be over 3000 watts in total. Or, in his specific case, 1500 watts total since he is using a lightweight power strip.

@@hughes500pilot1 Great answer and thanks.... I was wondering about that limited watt power strip. haha
@@hughes500pilot1 Thanks for putting all that information into simple understandable basics, it really helps, thanks!
Can we use 2 battery?
Of course, this system can be expanded in almost any way
@@SimpleCarGuy In your experience. How many of this battery do we need to power the house without hvac system?
@@TienTran-bi1jv with 2kw of panels you can use two of those batteries pretty well, 10kwh of 48v.
Now check out Rich rebuilds to see how you can get 400 Mi range out of the i3😊
I used to watch his channel all the time, but haven’t in a while.. now I have to check back again! That sounds amazing
@@SimpleCarGuy A pleasure..👍🏾
Is there not an APP for this? Doing all the changes with that little archaic LCD from 1967 is lame.
Yes, there is. You do have to be connected to WiFi though, which may not always be possible in off grid situations, so I wanted to show it live on the unit.
🧡🧡🧡💯💯💯👏👏👏👍👍👍
For the size it's output to your car is poor , need 3kw minimum chargeing
This same set-up has been done like 100 times on CZcams already. I'm sure you know this
What hasn’t been done on CZcams, though? It’s all about documenting it for myself and expanding the project further as I’m building it up.
Thanks for watching!
@@SimpleCarGuy We are almost done with this type of install in our camper van. And yes, I've been scouring YT for information. Your video is extremely helpful with little details that others don't cover. Thank you.
Sorry ALL EV's Need to be Outlawed and removed from the roads!!!
Why is that?
