you have to understand, when the generator generation rate is not stable enough, the regulator can do nothing to correct it.
you need a stable current, not voltage. if current is NOT stable. regulation of voltage is very limit to help.
unfortunately, I didn't find any "current regulator".
that is the reason why "generator" always a bad idea to use with inverter. you can't stabilize the supply of the current.
