METHOD FOR OPERATING INVERTER AND INVERTER ARRANGEMENT

A method for operating an inverter and an inverter arrangement (10) comprising an inverter (10), and a controller (100) configured to control the inverter (10) to convert DC power into AC power with a DC input voltage control by applying a maximum power point tracking, MPPT, during the converting, i...

Zusammenfassung:	A method for operating an inverter and an inverter arrangement (10) comprising an inverter (10), and a controller (100) configured to control the inverter (10) to convert DC power into AC power with a DC input voltage control by applying a maximum power point tracking, MPPT, during the converting, in response to the DC power supplied to the inverter (10) exceeding a predetermined power threshold value, control a DC input voltage of the inverter to a lowered value lower than a voltage value corresponding to the maximum power point, such that the DC power supplied to the inverter at the most equals the predetermined power threshold value, and after controlling the DC input voltage of the inverter (10) to the lowered value, control the inverter (10) to convert DC power into AC power with the DC input voltage control by applying the lowered DC input voltage value.
