Has anyone had issues with the inverter having internal fault problems when your hooked up to a 20 or 30 amp? At home on a 20 amp, my inverter fault light would do the 5 flashes signaling an internal fault usually a couple minutes after I'd reset it. On 30 amp, it lasted about a week then started faulting. When u reset it on the 30 amp, it would last a couple hrs or longer before faulting. Now I'm on a 50 amp and it hasn't started faulting yet, even when both acs are running.
I took it to the shop and they couldn't duplicate the problem, I think they were on 50 amp too.
