Hope someone can give me a bit of advice on the following :
Just changed motorhomes, and on our shakedown 1st outing I've got a possibly problem.
I've got a 90 watt solar panel on the roof, feeding into a Duo battery solar regulator, which is set to charge 10% engine battery and 90% leisure batteries.
Even in bright sun the LB's don't rise above 13.4 volts.
I've got a remote meter that talks to the solar reg and this gives me a bit of info, including the voltage that the panel is producing which I assume is reaching the solar reg. This voltage varies between 19 & 20.5 volts, but when I put a meter to the solar panel input terminals on the solar reg it only reads 13.2 to 14.5 volts. Why dosn't this read up to 20.5 volts as per the remote meter ?
A bit more info...I've got 2 x 110 ah Elecsol LB's, both 6 years old (approx), both showing 'green' in the magic eye, and both measuring approx the same voltage as showing on the remote meter, 13.4 volts.
I know Elecsols have not had good rep but would this affect the apparent discrepancy in the voltage readings described above ?
I'm likely to change the LB's in the near future even though the elecsol's look brand new.
thanks in anticipation.
