The maximum start voltage is the voltage of the PV panels that cannot be exceeded to start injecting power into the grid and/or batteries.

  • Page 48: 7�1�6�- Rcmu Calibration (Residual Current Monitor Unit)

    CirPower Hyb 4k-48 Implemented anti-islanding uses passive methods to monitor the grid voltage and frequency. It uses as well active methods that react facing any grid failure, and stop and disconnect the inverter in the time regulated by the local standard.
  • Page 49 CirPower Hyb 4k-48 During the charge/discharge process, there is measurement uncertainty that produces a meas- urement mismatch that accumulates over time. The consequence is a different value between real SOC value and calculated SOC value. To solve that issue, the CirPower Hyb self-adjust the SOC to 100% when it detects that the battery is fully charged.
  • Page 50 CirPower Hyb 4k-48 Charge stages: Bulk Bulk charge is performed when the battery voltage is lower than the absorption voltage. During this stage, the goal of the inverter is to keep the charging current constant. This stage finishes when the battery reaches the absorption voltage.

  • Page 56 CirPower Hyb 4k-48 Energy from solar panels will be used:  When loads are connected - To supply the loads. - If there is an excess, to charge the battery. - If battery does not allow further charging (SOC 100%), the PV generation is reduced.
