OK........
MAIN Breaker tripping. That means you are exceeding the 30A breaker cause too much AC equipment is being used at same time
OR the MAIN Breaker is weak.
Add up the amps (120V-----higher amps if lower voltage supply)
A/C unit Comp/11.5A Fan/2.5A----14A
Water Heater--------------------11.5A
Fridge--------------------------3.5A
Microwave (900W)----------------7.5A
That's 36.5A....just running amps. Starting amps WAY higher
And that isn't even counting the amp load when converter kicks in.
Put your water heater on propane
Put your fridge on propane
That's 15 amps right there
