    Product Overview Working Mode Working modes are available for you to choose in on-grid status, i.e Self use, Feed-in priority, Backup, Peak shaving, TOU, Manual and Smart Schedule. 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 26 Product Overview Time period Inverter working status 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 27: 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.
