String module with ambient temperature and humidity sensors

213.15 excl btw

The String Module is suitable with every Battery Module. The String Module is responsible for the measurement of String Voltage, String Current, Ambient Temperature, Ambient Humidity, and charge/discharge cycles.
Along with the individual battery measurements, Alpais appreciates the health and service life of the batteries depend on the battery environment and how to treat the batteries.

The general Alpais Battery Monitoring System has 3 main hardware components; Battery Module, String Module, and Control Module. Alpais BMS is a modular solution that consists of 1 Battery Module for each battery, 1 String Module for each string, and 1 Control Module for up to 4 String Modules. The String Module can connect up to 120 Battery Modules and 1 Control Module can monitor up to 480 Battery Modules on up to 4 String Modules.
