Can inverters (UL 1741) operate with small genset?
(OP)
I have 5-10 kW wind turbines - each turbine has it's own inverter. I have a 146 kW PV array with one inverter. The load is 100kW @ 480Y/277VAC 60Hz. I am installing energy storage (another inverter) to be able to store excess PV energy during the day and use it at night. I want to 'island' when the utility is not available. Can I add a small genset (10kW) to get the inverters to think they are connected to the grid?

If you do this, please video the results. Utility power is generally very stiff, and substantially determines the frequency for what ever source is connected to it. A 10Kw generator is likely a poor substitute, particularly when your load is 1000% of its capacity and another ≈ 200Kw of generation is connected. I would give better odds to your chances of success had you mentioned an electronic governed diesel set rated at least 125Kw.

But you don't say what kind of wind generators you have, AC induction, AC synchronous or DC. I would suspect, given the existence of inverters, that it is DC, but that would be a guess. Maybe you could tell us the entire story instead of just pieces?
