How to read this record

  • Nominal energy is not usable energy. Apply the depth of discharge and efficiency before comparing runtime.
  • Charge current must stay inside what the BMS and the inverter can deliver. A large bank can still be limited by a small charger.
  • Confirm the BMS communication protocol (CAN or RS485) matches the inverter before specifying a lithium bank.
