  • Page 15 installed at the battery end. Please refer to Chapter 2.2 “Wiring Specification and Circuit Breaker Selection” for their selection; prior to wiring, please be sure to disconnect the circuit breaker to prevent strong electric spark in the process of wiring and avoid short-circuiting the battery in the process of wiring; if the inverter is applied in any area with frequent lightning, it is recommended to install an external surge protection device at PV input.
  • Page 16: Working Mode

    3. Working mode 3.1 Charging Mode 1. Solar First: priority shall be given to charging by PV, and mains charging will be started only when the PV has failed. It can fully utilize solar energy to generate power in the daytime and then switch to mains charging to keep the battery level, and can be used in regions where the grid is relatively stable and the feed-in tariff is relatively expensive.
  • Page 17: Output Mode

    3.2 Output Mode 1. Solar First: PV and battery will power the load, with diversified charging modes available and output mode optional, when the Solar First Mode is selected, the use of green solar energy can be maximized for energy efficiency and emission reduction.
