I have a Growatt SPF 3000TL LVM and installed it in a RV. It's working great, aside from one little issue.
Input GFCI trips occasionally.
When I'm at home I plug in the RV with an adapter into an exterior 20A outlet (reduced the charging rate) which is protected by an GFCI outlet.
After a few hours (2-15hrs), the GFCI trips randomly. It resets easy no issue.
Inverter switch on - I've disabled all circuits in the RV at that breaker panel - and it still trips.
Inverter switch off - plugged in (so it's still charging the batteries) it's not tripping the GFCI.
Was wondering if there is a setting in the inverter, what could prevent that behavior. Or if the inverter has a potential fault.
It's not happening in RV parks with the non GFCI 30A outlet there. That would be my alternative plan to just get a regular RV outlet installed. But since there is some sort of Ground fault potential - I wanted to check here first. (and I got a new GFCI outlet ordered since the old one is 20+ years old and I'm not trusting it)
Further I got the feeling that as soon as the I plug it in - it goes in AC bypass mode - even with setting 01: SBU
