CECILANDDONNA Report post Posted May 16, 2018 I have two 120 watt solar panels, but my house batteries are not being charged. How do I check to see if my solar panels are working properly? Where do I check to find the problem? Share this post Link to post Share on other sites
richard5933 Report post Posted May 16, 2018 You might want to start by checking to see if your solar charge controller is connected and turned on. The panels usually connect to the charge controller, and this sends the charge to the batteries. There can be any number of circuit breakers or switches between, depending on your particular setup. Do you have the manual for the setup installed in your rig? Share this post Link to post Share on other sites
desertdeals69 Report post Posted May 16, 2018 In bright sun check the voltage output at the panels. What kind of charge controller do you have? Share this post Link to post Share on other sites
rsbilledwards Report post Posted May 17, 2018 The way to check simply is to climb up top, the panels should have a connector on them. Disconnect and with a volt meter, rake each lead one on one wire and the other lead on the other wire. You shold get a reading of something. Now you know with nothing in between what the out put is. Now you need to find the charge controller. Same procedure on the out put as described for the panels. There will only be two poins out. Look and see if the are a couple loose wires in the battery compartment not hooked up maybe it is as simple as that. Share this post Link to post Share on other sites
