My boat is on shore power and last week a thunderstorm tripped the on board RCD. Once this was switched back on all appeared fine. However, I now find that once the shore power is disconnected the Atlas Combi 12/1500 does not connect to the 240v system. When shore power is connected the battery charger is working and the inverter displays both ‘mains’ and ‘load on mains’. When the shore power is disconnected the inverter (depending on the switch setting) shows ‘on’ and ‘auto’, but there is no 240v to the sockets or lights. Fuse 1, 2 and 3 are all good when a multimeter is put across them. The on board batteries are supplying 12v. Can someone point me in the direction of a possible solution.
