While Anker or Ecoflow have better system, I have found the EG4 system to be the cheapest in terms of $ per kwh (example below). If anyone have better suggestions, please feel free and chime in.

- Low Voltage and High Amperage Solar PV Input. Only 60 volts max and 25 Amps. You can't hook both XT60 ports to an external car or server rack battery, they won't accept power from two sources sharing the same electric grounding.
- High inverter idle power usage. The inverter eats up 70+ watts just idling. That's about 1.68+ KWH right there for a whole day.
- AC input turns off when you're using the 240-volt output, you can only do solar input to keep it supplied with power.
- No dual input support, you can't charge using both AC and Solar at the same time (I heard firmware update changed this but can't confirm.)
If you're only this for short duration use, I think it will be just fine, but as a home power backup there is a lot to be desired with this. Its a nice platform but hopefully they come out with an improved mode that fixes these issues.While Anker or Ecoflow have better system, I have found the EG4 system to be the cheapest in terms of $ per kwh (example below).

If you want to stick to portable power stations, a fully populated 15.4 kWh E3600LFP + 4x EP3000 costs $4935 or 32 cents per kWh.
"I just want to store more energy" is exactly the use case the EG4 powerpro is aimed at. About 22 cents per kWh and a 10 year warranty, biggest challenge is moving 300 lbs around and installing it…
If you want to do a little assembly, a 4S 48V 280Ah stack of Ecoworthy batteries plus a set of battery cables typically costs around $1600 on sale, about 11 cents per kWh.

Everything is working fine so 15kw and 5k 120v output for like $2050 over the past 2 months. I used it for the last 7 weeks while camping, run the generator every other day for 4 hours or so to keep the battery between 20% and 80% (not a full charge). I plan to hook it up as backup power for the house and get some solar panels next year. The connections were not difficult and there is plenty of youtube if you don't know how. I spent another 300 or so on wire/terminals/crimper/breakerbox/fuses etc...
What I don't like is mostly about the inverter. can only charge shore/grid/generator power at around 2400 watts (120v 20 amps) as the battery charging setting can only go up to 40 amps (at ~60v to charge 48v battery). I found this annoying as I was running off generator for the last 2 months... If I could charge the batteries at a higher amps I wouldn't have to run the generator as long but even if that was fixed, I'd run into problems with input power being limited to 120v only. For $500 (on sale) for the inverter, I couldn't find anything remotely comparable and peace of mind not having to worry about finger pointing between eco-worthy and some other inverter company.
The "wireless" feature they give you seems to be worthless and the ios app/website are not functional or are too complicated for me to figure out and seems to be designed for reporting usage data rather than configuring / monitoring the system. I do regret not buying the bluetooth batteries which are more expensive because I want to know if the inverter is telling me the truth about its state of charge etc.
The US based support was fine. The manuals are bad as they refer to 3 or 4 different models and none of those models matched anything on my actual product.
I have the F3800 with an additional battery (about 7.6kWh total). That'll get me through the night powering my fridge and Window AC (which was my use case, since I'm in hurricane country).
