PV Inverters

PV inverters react to certain changes in the diesel generator frequency. With diesel generators, the frequency of the output voltage under load is 50 Hz. For this reason, the PV inverters will in most cases supply their entire power to the stand-alone grid, even when the diesel generator is in operation.
