New energy battery temperature difference too large alarm
Temperature alarms on charge controllers
I''ve got to MPPT 250/100s that are simultaneously reporting battery temperature high alarms. There''s no battery temp sensor connected. The battery temps are in the 50s F. Nothing is hot. It''s below freezing outside. It''s 50 degrees where the controller is. The controllers are not charging the batteries now. Help!
