A bit of help please and possibly just a bit of reassurance.
Until recently I was convinced that my SP system was working well but over the last week or so I have tried to check it. The van is in my drive not being used with all main systems switched off; it is not on EHU and has not been for about 10 days. The control panel has been showing both the vehicle battery and the twin leisure batteries holding a steady 12.7v without fluctuation night or day, cloud or sun. This afternoon I put a heavy load on the leisure batteries by using the invertor for a while to drive a 500w fan. The battery voltage dropped to 11.8 whilst the load was on but immediately recovered to 12.3v once the load was removed. Over the last two hours it has been in good sun and has recovered to 12.6v. I was expecting to see a much higher voltage as the batteries were being recharged. Does it sound as if the SP is charging the batteries or not? Any advice please?
