    Parallel System With the E8KT/E10KT/E12KT, you can connect up to four inverters of the same model in parallel to build a parallel system. In a parallel system, loads must be connected in parallel on both the on-grid and backup sides. Compared with a system installed with one inverter, a parallel system expands the system capacity.
  • Page 32: Scenarios

    • In a parallel system, all settings must be the same for all inverters except for the addresses of the inverters. Scenarios The E8KT/E10KT/E12KT can be used in both a DC-coupling system and an AC- coupling system. 3.8.1 DC-coupling System In a DC-coupling system, the DC electricity generated by the PV panels is directly sent to and stored in the batteries through the inverter.
  • Page 33: Ac-Coupling System

    AC electricity back to DC electricity, and then store it in the batteries. An AC-coupling system is ideal for retrofit. The E8KT/E10KT/E12KT supports two AC-coupling system schemas. If you already have a PV inverter and now want to add an energy storage system to the inverter, but no PV panel is available for connection, you can use AC- coupling system Schema 1.
