installers,
so as to not reivent the wheel.
any experience with connecting a grid PV system on the load side of an 
automatic transfer switch?? fronius ig plus or sma's either one.
the genset is a natural gas that modulates with load-- so it is a step 
up from a menards portable type.

assuming the solar is over producing the home usage (its a 10 kW system 
so it could very well), the genset is still holding a "grid" albeit at 
idle, the inverter will not necesarily know what to do except keep 
wanting to produce "current (amps)".

who has already tackled this??

further there is talk of a battery system possible. but the 7 kW genset 
would be stronger than a stacked pair of out back inverters, and or too 
much capacity for the FM charge controllers to go to the battery.

comments?

Thanks,

Craig
