We brought our Fogstar Drift ECO for our caravan 11th October, it is fitted with a Victron MPPT controller and 2 x80 watt solar panel in series, the isolator switch in the caravan is off to date the battery and solar has held good charge, over the last few days despite being feed by the solar the battery in the day dropped back to 12.7v, for some reason yesterday morning it dropped below 8v.
I have checked for any leakage, none showing, the battery has now recovered to 11.74v, this morning showing 11.5v.
I contacted Fogstar yesterday, they have raised a ticket and aim to respond in 72 hours?
Unfortunately I have suffered a brain injury and occasionally I get confused and often say the wrong thing.
