Yes I'm in a Marina with shoreline electricity. Have plenty of credit, tried 2 different cables, no appliances were on.
What is confusing me is that all was fine when I left.....fiddled with the Victron charger/mains switch and eventually got power back.
Second time (yesterday) switch flicking got mains light on, then bulk followed by absorption but then kept cutting out before getting to float. I have no idea what any of these terms mean but know I have mains electric when Float is lit.
Persevered for an hour, lost the will to live, went out. Came back 6 hours later and all was fine !!! Really need to understand what the issue is and how to reduce likelihood of it happening again. 😟
