One thing confuses me re sizing the correct breaker for AC 1 output. If you hooked to 15A shore power + using the multiplus power assist, then your looking at around 28 Amps from AC1 output.
if you allowed for that and to be conservative put in say a 25A breaker on AC1 output. Then when your not using shore power and using batteries only, then the breaker is too big for inverter only which is only going to be around 12-13 Amps.
This to me is a problem as inverter only then the AC1 output is not being protected properly.
Am I missing something, is there a way to properly allow for and protect AC1 output when using Shore + Inverter and then when your off grid and Inverter only ?
