I have had this inverter for a long time but only hooked it up this year.
Works fine but I have no need for it.
I'm including the circuit breaker.
I believe this is the right one for the inverter but you need to double check it.
I'm not an electrician by any means.
$120 + $15 S&H
Also the cables I used are included.
They might save you a few dollars.
