15 Appendix 15.1 Application of Parallel Function 15.1.1 Introduction of Parallel Application The series inverters supports parallel operation in both Grid and EPS modes. It supports up to 10 units in the parallel system. This function will be released in quarter 1 of 2025. 15.1.2 Notice for Parallel Application •...
Appendix NOTICE! • The communication cable length between two parallel inverters should not exceed 2 meters, and the total cable length of all parallel inverters should not exceed 15 meters. • When multiple inverters are connected in parallel, they can share one battery cluster. For details about the wiring procedures, please refer to the corresponding user manual of the battery.

Appendix Communication cable wiring-COM terminal and COM terminal Use standard network cables for Master-Slave inverter connection. Master inverter Parallel-2 connects to Slave 1 inverter Parallel-1. Slave 1 inverter Parallel-2 connects to Slave 2 inverter Parallel-1. Meter/CT connects to Meter/CT-1 or Meter/CT-2 terminal of the Master inverter. The following wiring is taken Meter/CT-1 terminal as an example.
Appendix 15.1.5 Settings for Parallel Connection Parallel setting >Parallel Setting Setting path: The series inverters support up to 10 units in the parallel system. Master/Slaver Settings: You can set the state of inverter to Single or Parallel. • When parallel, the state of inverter can be set to Master/Slave. Select Master for the master inverter and Slave 1~9 for the slave inverters.
Appendix 15.2 Application of Generator 15.2.1 Introduction of Generator Application When utility power supply is unavailable, the system can seamlessly switch to the generator for power supply and collaborate with the energy storage system to ensure the uninterrupted use of the load. In this case, the generator functions as the power grid to supply power for the load, and the hybrid inverter converts the solar energy to electricity.
Appendix 15.2.3 Dry Contact Mode In this operating mode, users can intelligently control the system by establishing a dry contact connection between the inverter and the generator. It allows for adjustments to multiple parameters so that the system can meet the requirements of different scenarios. Wiring connection diagram Inverter SolaXCloud...
