Remote Temperature Sensor Converter Adapter
★Fit for Tracer BN/A series MPPT charge controller ACOPOWER HY-MPPT
★Acquisition of battery temperature for undertaking temperature compensation of control parameters
Taped to my batteries and connected to charge controller. Had a few cold days here in Florida and it did change how the charge controller charged the batties
Plugs right into my Epever solar charge controller. This sensor should improve battery charging by providing the controller with true battery temperature data. The wires on the plug seem very frail and exposed though, so I taped around them to provide some protection and support.
