Product overview

The BMS board manages cell voltage balancing, temperature monitoring, over-current protection and communication with the inverter through the RS485 and CAN interfaces. A faulty board can cause the battery to shut down, lose communication with the inverter, or report an incorrect state of charge. Fitting a genuine Pylontech replacement restores correct operation.

This board only fits the US3000C. Contact Voltacon after purchase for the correct installation instructions before any work begins on the battery.
