Where is the best place to connect your Solar panel. Dethleffs want it connected into the control box Which mine is. This I believe means that it is not charging the batteries whilst driving. But talking to another knowledgeable person he stated if it is wired direct to the batteries it will charge them whilst driving in addition to the alternator. Also when connected to EHU the control unit charges both leisure and main battery. But when using just solar the solar panel connected into the box only seems to charge the leisure battery. Any ideas folks.
