Yep...also try telling my missus that she has to do anything if the lights go out in the middle of cooking dinner...or the toilet won't flush cause the water pump ain't working from the tank water..

Hope I've helped.

I don't think you can synchronise the generator to the PV inverter, many have tried and all have failed. Being even a tiny fraction of an AC cycle out presents itself as a short circuit....the bigger the phase shift the bigger the short circuit....usually a bang.
But...there are inverters around that take care of all that.
An AC coupled system with say...a Sunny island and SMA grid feed inverter will do exactly what you require including controlling the generator...this can be done on battery state of charge and even can start the generator to aggregate the AC load if say...welding etc.
