When I installed my Morningstar SunSaver MPPT controller several years ago I followed their instructions which stated that no inverters should be connected to the load output terminal. Since I don't have an inverter - no problem. I just wired the camper master switch to the controller load terminal. This allowed the Morningstar controller to log current out put and amp hour usage plus provide low voltage disconnect.
Recently I was looking at the Morningstar web site and found out they changed the installation instructions to not attach any inductive load to the controller load terminal. This includes inverters and motor driven devices (compressor fridge, heater, water pump, vent fans & etc).
I contacted Morningstar and their tech rep said that I've been lucky to not have had any problems so far and it may have to do with the combination of items that are on and their cycling sequence. He recommended these items be powered through a relay and flyback diode and sent this article.

This would be an easy mod but I would loose the load usage logging capability. I think I would rather loose that capability than try to find a replacement solar controller in Mulege next year.
Can any of you EEs out there weigh in and give this ME some advice.
