    Product Overview Working Mode Six working modes are available for you to choose in on-grid status, i.e Self use, Feed- in priority, Backup, Peak shaving, TOU and Manual. You can choose the working modes according to your lifestyle and environment. When the power supply from the electric power company is stopped due to a power outage, it automatically switches to EPS mode and connects to the distribution board for a specific load, thereby providing power to important electrical appliances.
  • Page 23 Product Overview PV is sufficient (PV → load → battery → grid) • The power generated from PV prioritizes supplying the load. Any excess power is then directed towards charging the battery, and if there is still surplus electricity, it can be sold to the grid.

  • Page 24: Feed-In Priority (Priority: Loads > Grid > Battery)

    Product Overview 2.7.2 Feed-in Priority (Priority: Loads > Grid > Battery) The feed-in priority mode is suitable for areas with high feed-in subsidies. The power generated from PV is directed towards supplying the loads. Any excess power beyond the load requirements will be fed into the grid. Feed-in Priority Power (Assu ming p eak p ower from 7: 00 to 23: 00)

  • Page 25: Backup Mode (Priority: Loads > Battery > Grid)

  • Page 26 Product Overview The working logic remains the same as for self-use mode. The difference is: • In the self-use mode when there is no PV input and the battery SOC reaches Min SOC (on-grid min SOC), the battery will enter a dormant state. At this time, if the grid power is lost, the Allowed discharging inverter cannot switch to EPS mode.
