An atmospheric discharge induces an overvoltage in the U cable, which in turn induces an overvoltage in the loop constituted by the string below and its connections to the inverter. There have been several breakdowns. There are SPDs, DC and AC.
The U cable is all resting on the string. The owner...
This is my case: an inverter is connected to the grid via an RCD. The RCD often opens, so the entire photovoltaic system, from the panels to the inverter output, is powered by the panels but without load. The inverter has failed multiple times for no apparent reason, with the VDRs failing. Is it...
Good evening, a silly question, I don't know the sector.
What happens to the inverters in the event of a sudden disconnection from the grid of a photovoltaic system, for example due to an intervention of a RCD, or fuse, or circuit breaker between the inverter and the grid?
