System and Method for Operating an Inverter

An inverter () connected to an energy source () and configured to supply power to a load network () comprising at least one controllable load, said inverter () comprising a processor () adapted to control the at least one controllable load of the load network () is disclosed. The processor () comprising: a net load detector () detects a net load of the load network (); a power export analyzer () determines an inverter power transfer of the inverter and a grid power transfer of a grid (); characterized in that a power manager () varies the power output of the inverter () and a power consumption of the at least one controllable load based on the inverter power transfer, the grid power transfer, an export condition violation and a derating state of the energy source ().
