I have a multiplus 3000/12/120 unit installed on my catamaran together with a generator and LiFePo4 batteries. My installation has been running for about a year now. Over the past month a strange thing has started happening . When I start my generator the charger does not kick in. I then reset the multiplus through my cerbex and then it kicks in. This has started happening at least once a week. Today things seem to have got worse. The charger does not kick in even when I reboot the multiplus ( last night it worked perfect) without reboots or anything. I change the switch to charge only and turn on the generator. The mains blue light comes on for a few seconds and then the float light illuminates for a second and the unit shuts off. My batteries are at 13.2v and are 29%. I shut down the generator and reset and restart everything but the same happens. On the power output side without the generator the inverter is giving 220v so that is fine
