This maybe a dumb question to ask but do you put a 30a breaker in the main panel and one in the sub panel? I'm thinking not. the inverter Magnum 2812 is 30 a pass through. I have ordered my inverter and looking for the sub panel which is hard to find a 120v sub panel like the one at AM Solar which I did find cheaper, or is there another choice.UPDATE: the manual states 30a breaker on both sides of the inverter one at the main and one at the sub panel

I will admit, I have no clue what you are talking about. But I did a Google search and hit upon this. The discussion is on sub-panels. Maybe something here will help you out: Click here.

Both sides of the inverter should be fused for safety sake. 30A inverter is probably 30A out put so 30A breaker there. Input will need way more than that.

The only place you need a fuse or breaker is where there mite be a short circuit :)

If I remember correctly the Magnum will have input and output breakers built in. They're little push-in style breakers. You don't need a main in the output sub panel; the input breaker will prevent overload of anything downstream. But, extra breakers don't hurt anything.
