In my cabin I have an off grid system with 1Kw panel, a Tristar 45TS controller and an inverter. A contractor ran over the line and broke the wire from the panels so the batteries did not get charged for 2 months. I repaired the line but the controller is getting 19.5 V from the panels but not starting. The battery bank has 6.5 V. The batteries were 13.5 V just before the break. I tried a spare Tristar 60 TS I had and also did not start. I read the controller manual and it said that the controller will not work unless the battery is at 9.5 V. What are you supposed to do? Charge your batteries another way such as using a generator?

Update. I connected a generator to the batteries (2 batteries @ 100 Amp) and in 2 hours the batteries were at 12.5 V. This should be close to 100% as normally the batteries are at 13.5 V. However, the controller had the yellow and red LED on, indicating the batteries are 0-30 % charged. I am not sure what the controller is saying. Thank you Shemdogg for the desulfator charger tip. I will get one. I must confess, that name sounds more like a nasty medical procedure.Comment
