The BMS1230S3-SK battery sensor assembly monitors battery conditions and state of charge even while The Manager30 is in standby mode. The battery sensor monitors current, voltage and temperature of the house batteries.

This is a spare part only. The Manager30 battery management system comes with the battery sensor assembly included as standard.

This replacement battery sensor assembly is compatible with the BMS1230S2 and BMS1230S3 Manager30 models.
