Better check the voltage of each panel with it in very hot sun. When I bought my last MH, I could smell sulfur smell in the heat of summer. I pulled the battery covers and discovered some moron had hooked up both solar panels in series then hooked to one 6 volt battery. Each panel was putting out 19 volts so that was total 38 volts going to one 6 volt battery. I also noticed that battery was a different model than the rest. Guess he didn't figure it out. Who knows how many batteries he went through
