The inverter itself is great, but it’s suitable only for very small installations. Well, a 5kW one actually is fine. Too bad it’s grid -tie, i wanted to use it for my van(

does it keep working when grid goes down?
A1 SolarStore
No. All grid-tie inverters are required to shut down during power outages for safety reasons.
