When bridging the neutral and earth on the inverter output during islanding mode, there are basically 2 ways of doing it and achieving the same result.
Which is the correct way and why ?
A. Use a normally open contact on the relay and energise the relay coil from the inverter output. Or.
B. Use a normally closed contact on the relay and energise the relay coil from the inverter input.

Ok, stupid question. Must be B. Inverter output is always there, whether in islanding mode or not so the relay will remain energised permanently.
