I am using an eco worthy 5kw inverter hooked up to a pair of 5kw server batteries , cubix100s at my off grid cottage, I hooked the system up last week and didn't have much time to mess around.

My first issue was it not seeing any solar, I have 4 older 280w panels and they were in 2+2, I think the issue is the voltage was too low, I set them all in series and that seemed to do it.

I was away for a week with essentially no load, the RV is still plugged in but nothing was being used, now I showed up a week later and the batteries are at 18% and the inverter is beeping and flashing an " low voltage" under the PV ? How could it have not charged in that time ?

I tried going through the settings again, still not 100% sure I got them all but I think so. Is the minimum amps for PV charging actually 2amps ? So assuming I make 140v, I need to be making 280w before it'll even try to charge?

I upgraded from a bluetti ac200p to an eco worthy inverter and a pair of 5kw server batteries for an off grid cottage build. I set everything up last weekend and found a couple less than ideal issues.

The minimum PV voltage means I need to series connect 4 panels for the inverter to even register PV charging at all.

The batteries work with Bluetooth and the ecoworthy app but I don't have wifi available and the app doesn't include anything indicating how much solar I'm making, only says whether I'm charging or discharging, if like to see how many watts I'm making and how many im using.

The inverter came with a dongle that works with the solar man app, this is capable of showing solar in vs inverter out but that requires a WiFi connection.

I think the longer term fix will be to buy the external screen for the inverter, just wish there was an easier way than using 2 apps , one on Bluetooth and the other Wi-Fi even though everything is connected by network cables
