Bear with me....
We havea Rapido 983M currently with two 85Ah batteries (new within the last 6 months) plus two 80w solar panels. Currently in Portugal and having electrical problems.
Once the batteries are fully charged, we only get about one hour ov TV and a couple of hours of having a couple of lights on before the panel shows the batteries at less than 12V and the alarm goes off.
Two nights ago we went out and didn't use the TV or lights at all (candles only when we got back in). Next day solar panels had the batteries back to 12.2V (as shown) so we used candles again and didn't use anything electrical except water pump. At 5:00am the panel alarm went off showing batteries fully discharged at 11.0V !
Last night I carried out an experiment - solar panels had the batteries back up to 12.2V again and after another evening by candlelight I turned the panel off completely using the main switch - in the morning the panel showed the batteries still at 12.2V.
Interesting - but what the hell can be draining the juice?
Anybody got any ideas?
I might not be able to respond very quickly to questions or comments as I'm having to walk into town to find a cafe with wifi.
All advice gratefully received.
