Claim 9:
10. A method for operating an inverter for optimization of power generation of an energy source, said method comprising the steps of:
detecting a net load of a load network;
determining an inverter power transfer of the inverter and a grid power transfer of a grid to the load network; and
controlling the power output of the inverter and a power consumption of at least one controllable load of the load network based on the determined inverter power transfer, the determined grid power transfer, a detected export condition violation based on an allowable amount of power transfer to the grid, and a derating state of the energy source;
wherein controlling the power output of the inverter and the power consumption of at least one controllable load of the load network comprises:
decreasing power consumption of the at least one controllable load depending on the grid power transfer, in response to determining the energy source is not in the derating state, under a presence of the grid power transfer and no export condition violation;
checking the derating state of the energy source; and
increasing the power consumption of the at least one controllable load by a predefined value in response to determining the energy source is in the derating state.
