I have several small systems and a few I have helped friends with. I use a Magnum PT100, EPEver 100a, EPEver 80a, EPEver 50a, EPEver 30a, Victron SmartSolar 100v | 50a, Victron SmartSolar 75v | 15a
I have recently installed a few lithium systems and am worried about temperature, since I live at a high elevation where temps get below 32F. I have heating pads installed, but say they fail. I have installed temperature sensor modules that will disconnect the batteries from the charge controller and any loads. If any of these controllers start getting PV while the charge controllers are disconnected from the batteries, will the charge controllers get damaged by the incoming power from the panels?
Will all, some or none of these charge controllers be okay in a battery disconnect situation?
If they do indeed risk damage, should I install a relay on the PV circuit that turns the PV off as well?
