So far I've got my 4th inverter. The previous three all broke down. For all of them, one of both DC channels failed. There was no error logged.
The system has been checked by the installer, but they couldn't find anything wrong.
The system has 2 strings of 11 panels totaling 4290 Wp (2145 per string)
My Neighbours have exactly the same installation. They have had no problem with their system.
The only difference that I could find is that my DC wires come from the right side of the inverter, cross the WiFi antenna and are then connected to the inverter (see photo). At my neighbours site, the DC wires come from the left side of the inverter and are not crossing the WiFi antenna.
It seems far fetched but is it possible that the WiFi antenna interferes with the DC leads and could cause the inverter to break down?
