Definitely good to have an extended warranty on the inverter/s.
With something like a not so big off-grid setup, you do the grunt work and then have an electrician hook up the panels to inverter etc. if you don’t know what you’re doing. Gonna pay out your ass to have a solar company do it all.
Not sure if I told you this yet. Turns out, that even though you have to have a minimum solar system on new construction here in CA now, i don’t have to. There was an existing house that had burned down on this property around 8 yrs ago
That and fire sprinklers. Don’t HAVE to do that either because replacing a house. Not to mention i’m saving around 6K of impact fees i don’t have to pay.
