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
Some or all of the specifications usually appear on the inverter data sheet. Maximum AC output power This is the maximum power the inverter can supply to a load on a steady basis at a specified output voltage. The value is expressed in watts or kilowatts. Peak output power
The setting is percent-based. 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 generate a maximum of 3.6kVa (for EEG2012, 70% of the kWp of the PV array) and the inverter has a nominal rating of 5kVA.
It's important to note what this means: In order for an inverter to put out the rated amount of power, it will need to have a power input that exceeds the output. For example, an inverter with a rated output power of 5,000 W and a peak efficiency of 95% requires an input power of 5,263 W to operate at full power.
And they should give you your deposit back if you are not happy. But great question about the export limiter. An export limiter of, for example, 3.5kW on a 5kW inverter will not limit the output of the inverter to 3.5kW. It will (if properly configured) limit exports to the grid to 3.5kW.
