Control Maximum Active Power Generation
It is the desired active power limit divided by the nominal power of the inverter, as shown in the equation below. For example, this means if a user wants the inverter to only
In this example, the system has 12kW DC power connected to a three-phase inverter with a maximum AC power of 10kW. The system export power limit is set to 3kW, and the Per Phase Limit Mode is used. This means that exporting power on each phase is limited to 1kW.
In this example, the system has 12kW DC power connected to a three-phase inverter with a maximum AC power of 10kW. The system export power limit is set to 70% of max DC power, that is, to 70% x 12kW = 8.4kW, and the Total Limit Mode is used. Systems in Germany complying with the EEG2012 70% limitation would be configured using the Total option.
PV inverters are designed so that the generated module output power does not exceed the rated maximum inverter AC power. Oversizing implies having more DC power than AC power. This increases power output in low light conditions. You can install a smaller inverter for a given DC array size, or you can install more PV modules for a given inverter.
Export limitation of an inverter connected to an AC coupled battery is supported in inverter CPU version 3.24xx and higher, provided that the export limitation is greater than 0. In the Limit Control menu, select Limit Mode. Select one of the limit modes displayed below:
