Need help to troubleshoot a problem with our roof mounted solar panel system consisting of three 15 watt solar panels.We just backed our travel trailer into the driveway to prepare for a trip. It was stored for the last 5 months. Our batteries were completely dead (due to a light left on) Our charge controller first showed that it was charging, but after a day parked in the sun, we now have NO reading on the controller (no lights) and still have dead batteries. We have checked all the connections to the batteries, to the panels and at the wire connections just inside the trailer. All looks good. Our manual had no mention of a fuse in the controller, so not sure where to start?? Could our controller just be worn out?
Optional Information: Year: 2002 Make (other): PROWLER Engine: N/A
Hi There!!
Thanks for Choosing Just Answer....
Can you tell me what the name on the controller says, most do have a fuse...
Thanks Robert
The brand is - ICP Global technoligies
Their web site was not user friendly at all. Looks like they've sold out to another company. This set-up is probaby about 10 years old or so. Been great - no problems until today.
OK
Most of these are in-line with the battery and need voltage to work, so if your batteries are depleted I would go have them load tested to see if they are good, most auto parts stores will do this for free. IF the controller still does not come on I would look for an in line fuse or auto breaker on one of the cables at the battery. Sometimes they will tie this in to another auto breaker on the frame. So try and find the charge line from the solar panel controller to the battery. IF you do not see any fuses on that charge line I would suspect the controller has failed. I would see what happens with a fully charged battery....
IF you have any other questions or concerns please feel free to contact me...

I think I found some information and I do not see that they are using a fuse or breaker.....Click HERE and have a look..... It also says it will take 30 hours in direct sun on a depleted battery... But I have seen batteries so dead that it would not matter....
Experience: 10 Years RV experience... Cummins North West, Country Coach, Monaco Coach, Vendor certs.
Makes sense - just too dead for the controller to control anything....
We'll leave our battery charger on the batteries over night and see if it all lights up in the morning. Both batteries (deep cycle 6 volts) are only 2 years old, so hopefully we have just drained them and they can re-charge. Thanks for the help Robert!
No problem....
Let me know if you need more help.
Have a great evening, Robert
