I thought this might save someone some time. I was scratching my head trying to figure out why the batteries were not charging plus there was no wattage being shown from the solar panel. There was voltage from the solar panel just nothing to the batteries, finally took the controller off the wall and found a 20 amp fuse that had blown in the controller. Removed and replaced the fuse and all is working well.

Jim,
I have no idea what blew the fuse, solar panel charging had not worked since I brought it home. They hurriedly put in the second battery they had promised us so maybe something happened there. I did stick around for about a hour just to see if it would blow but nothing happened. I was surprised it was a 20 amp fuse on a 75/15 controller.

100% they connected battery wrong at first.
