Solar controller questions/help
First I would like to apologize if this is a dumb question. We installed two 165 watt solar panels and a charge controller wired to two 12 volt batteries in parallel this winter. Charging light came...

AFIK this controller has one set point Full Charge Cut the default is 13.7v
In float it should have the battery @ 13.7v, make sure it is set correctly.
Camping 14.8 would be good, in storage 13.7 is ok.
In BULK, probe the connecting terminals, they should be batt voltage (both panel and batt & battery posts) and on the rise till they hit the set point 'Full charge cut'
Eventually (when the batt gets to set pt voltage) the panel terminals voltage should rise as high as 21v (for a 12v panel and may jump around).
In float the panel v will be high and the batt terminals should be set pt voltage as well as the batt posts.
