An alternative circuit that switches in an additional load would be,

This is probably easier to understand. (R4 is the heater)
The relay wouldn't chatter as hysteresis is inbuilt.
<edit>This has the disadvantage that when 150V is reached it reduces the load on the turbine and the turbine would speed up. Not really desirable.</edit>

Been doing some thinking....
If I were to obtain a second Inverter, I could wire up this second inverter as the 'load' in series with the first inverter, and then drive two of them when the voltage exceeds say 140 volts. If this 140+volts occurs, then both inverters get exposed to the current, and each would get 70+ volts. I could then let the circut run to 180 volts, and each inverter would get a maximum of 140 volts....
When the total input voltage dropped below the 140 volt mark, the second inverter would be disconnected, and the result would be only one inverter getting the say 139 volts.
Does that work in theory?
