Why does my generator voltage rise with increasing load?

Dear All, I am trying to power up a micro-grid providing power to over 50 households and businesses on a remote island in Lake Victoria. I am using a Victron 3kVA inverter/charger coupled with a solar/wind set-up. I have been trying to connect a petrol generator to make up for a shortfall in power when the battery voltage gets too low. The 3.5 kVA rated generator will charge the batteries through the inverter/charger if there is no load. As soon as there is a load (ie people using power) the voltage of the generator output rises. The more the load, the higher the voltage. Eventually the voltage rises above 270V and the inverter/charger cuts off the generator at which point it settles back to whatever I set the AVR (Automatic Voltage Regulator) to. The generator is a German-designed Golf. Question: Why does the generator voltage rise? How can I get round this problem? Help! Any thoughts most appreciated!
