Why the backup: (this is from a discussion I had with another member just this week!)
Some gridtied systems have inverters have a safety (enphase is one) that must detect active 60 cycles to allow the system to operate.... If there is no power coming to the system, the system will not generate... So if the incoming power is down, the PV will not generate power....
There are installations that do allow a conversion, but usually are more costly - I do not know if the Kumukit system allows PV power generation when the power is out on the grid....
something to think about.... What back up do you have if there is a long power outage...
