Hello! So we picked up our rig last year in august and have been full timing it for about five months now. the solar system has been giving us problems from the beginning and we recently switched out the monitor, but the panels still aren't charging the deep cycle battery. it stays at about 11.74v, based on a plug-in reader. I will include a picture of the monitor soon, but it was recommended by the folks at ML Solar down in Campbell, CA who mostly do house panels. We couldn't figure out the rating of the two panels on our roof, but the controller is rated at 20 amps and it was only $20 so I went with it. Ideally, the plan is to hook up the cabin battery to the relay that exists under the hood, so that the alternator will charge the cabin battery when driving. However, when we are docked, we would appreciate it if we could get the panels to function as they should. I believe that there is either a passive leak/drain somewhere OR the panels, which seem to be wired in serial, are wired incorrectly. The monitor shows a charge coming in from the panels -- again, I will post a pic of the monitor soon. The previous owner seems to have wired the cabin battery to the cabin lights and into a 12V outlet, and bypassed the AC converter and breaker -- so none of the outlets function. Has anyone successfully installed solar panels to charge their deep cycle marine battery in conjunction with the alternator relay? Anyone have experience with this model of breaker/converter that I've posted below? Thanks for all your input! Cheers! 1984 Toyota Dolphin
