Application Notes
1. Introduction Italian regulation requires that all inverters connected to the grid first perform an SPI self-test. During this self-test, the inverter checks the trip times for over voltage, under voltage, over frequency and under frequency – to ensure that the inverter disconnects when require...

1. What is temperature derating? Derating is the controlled reduction of the inverter power. In normal operation, inverters operate at their maximum power point. At this operating point, the ratio between PV voltage and PV current results in the maximum power. The maximum power point changes cons...
