I have a 12/3000/120 Multiplus which is only 4 months old on our Catamaran, the other day we lost shore power to the yacht but the Multiplus failed to go into invert mode but to some strange reason there was still 240v power at some power points but the unit was not in inverter mode, I tested a few times by cutting the incoming 240v power from the grid and still no inverter mode, but was still showing that there was 240v power coming in as per the led's. This has happened a few times now but sometimes it will go to inverter mode as per normal operation any suggestions anybody.
Cheers Rod.
