haven't used the motorhome for a few weeks now , and it suddenly occurred to me that the batteries are being constantly charged by the array of solar panels
so I put the meter on the 12v output to see what voltage they were actually showing ...answer ...13.9 volts
question is , is it ok to constantly keep the batteries at this voltage[ well , not overnight I presume ], I am aware that the amperage isn't that great , but don't really know if the batteries being kept under charge will suffer any damage at this level
any info on this ?
