Hi all. I was gifted the Harbor Freight 100W solar kit. I was unimpressed with the charge controller and found the renogy line on this site. I picked up the Renogy Rover 20amp controller and finished the swap last night. Unfortunately today I noticed it is not charging the battery. I verified all the terminals and checked the solar terminal with a multi-meter. It showed about 13 volts which is about inline with what the panels would produce on a rainy/cloudy day. Yet still no charging. I wanted to make sure I didn't mess up something during the swap so I hooked back up the cheapo controller and it instantly started charging the battery. I have no error codes and in the Rover menu it does show panel voltage but no output amperage to the battery. The PV indicator is off which the manual says it means it has no connected solar array. Any ideas?
