Battery module

A battery module is a physical battery unit used as one building block of a modular home battery system. It may be one stackable unit in a tower, one rack-mounted unit in a low-voltage system or one product-specific pack inside a battery family. It is not the same as a single battery cell, the whole battery energy storage system, the inverter, a BMS, an expansion-right promise, DNO approval, MCS certification, export-tariff acceptance or proof of backup power.
