Had a call from a customer we had installed their small array back in 2011. System is not generating and panels showing on a rainy Sunday 305v zero watts.
Green light flashing once per second in waiting mode even on a sunny day. Was a good day yesterday 24oc No fault codes/ messages or blink codes on the inverter. Measured voltage 243vac at the inverter, 24v neutral - earth, zero volts N-E at consumer unit.
Would this fault be more likely the array strings rather than the inverter
