The inverter’s DC input current should always stay within its maximum limit. If the PV module’s output current exceeds this limit, it may lead to current-limited operation and potential inverter damage, reducing power generation efficiency and return on investment.
It is clearly evident that maximum exploitation of the inverter’s capacity is achieved due to simultaneous injection of active and reactive power without curtailing the active power as shown in Fig. 8 d.
The values of „maximum inverter power“ have always positive sign. Therefore they only limit the charging values for grid setpoint. They cannot limit the negative values for grid feed in. Using Grid feed-in → Limit system feed-in instead, also cannot solve this problem.
1. Maximum Input Current Definition: The maximum operating current allowed to pass through the PV side of an inverter. The input current is especially critical in scenarios with high peak power currents, such as those involving thin-film PV modules.
