    Your Smart Energy Terminology Terminology 1. Battery Management System (BMS) Monitors the operational information of battery cells, battery packs, and system units (such as voltage, current, temperature, and battery protection parameters), and intelligently assesses the state of charge (SOC), state of health (SOH), and total energy output to ensure battery safety.
  • Page 6 Your Smart Energy Terminology On-grid systems typically consist of PV strings, PCSs such as G2-H30/H50 inverters, battery systems, and the power grid. When the electricity generated by the PV strings is sufficient, the excessive electricity can be fed into the grid. When the electricity generated by the PV strings and battery system is insufficient, the grid can supply power to the load.
