Page 23: Working Mode
Product Overview Working Mode When an inverter is in on-grid state, there are 6 working modes for you to select: Self use, Feed-in priority, Backup, Peak shaving, TOU, and Manual. You can choose one of them according to your lifestyle and environment. When the power supply from the electric power company is cut off due to a power outage, the inverter will automatically switch to the EPS mode and connect to the distribution board for specific loads, thereby providing power to important loads.
Page 24: Feed-In Priority (Priority: Loads>Grid)
Product Overview Time period Inverter working status PV is sufficient (PV → load → battery → grid) • The power generated from PV is supplied to the load first. After that, the remaining power is used to charge the battery. If there is still surplus electricity, it can be sold to the grid.
Page 25 Product Overview 2.7.2 Feed-in Priority (Priority: Loads>Grid) The feed-in priority mode is suitable for areas with high feed-in subsidies. The power generated from PV is supplied to the loads first. If there is power left, sell the remaining power to the grid. Power Feed-in Priority (Assuming peak power from 7:00 to 23:00)
Page 26: Backup Mode (Priority: Loads>Battery>Grid)
Product Overview range is 10%~100%. NOTICE! • You can set two working periods: forced charging period and allowed discharging period. Please refer to "Charge & Discharge Period" for details. • In feed-in priority mode, consider whether the battery can be charged during the daytime.
Page 27 Product Overview 2.7.3 Backup Mode (Priority: Loads>Battery>Grid) The backup mode is suitable for areas with frequent power outages. In this mode, the battery power amount is maintained at a relatively high level, to ensure that the emergency loads can be used when the inverter disconnects from the grid. Its working logic is same with that of the self use mode.
Page 28 Product Overview Min SOC (off-grid min SOC): Minimum SOC under off-grid conditions. 10% by default, the settable range is 10%~100%. NOTICE! • You can set two working periods: forced charging period and allowed discharging period. Please refer to "Charge & Discharge Period" for details.
Page 29: Peak Shaving Mode

Page 182: Application Of Micro-Grid
Appendix 15.5 Application of Micro-grid 15.5.1 Introduction of Micro-grid Application Due to the islanding effect, an on-grid inverter cannot work during off-grid. This characteristic makes user losing the on-grid inverter PV energy when off-grid. Micro-grid is the function that making hybrid inverter simulate the grid to active on-grid inverter during off-grid by connecting the on-grid inverter to hybrid inverter's EPS port.
Page 183: Working Modes
Appendix 15.5.3 Working Modes Grid on • When PV is sufficient, the hybrid and on-grid inverters power the common and EPS loads together. When there is surplus energy on the on-grid inverter, it will also charge the battery. • When PV is insufficient, the hybrid inverter, on-grid inverter and grid power the loads together.
Page 184 On-grid inverter output power ≤ Max battery charging power NOTICE! • Since X3-HYB-G4 PRO series inverter is unable to control the output power of on- grid inverter in grid connection mode, the series inverter cannot achieve zero export when "loads power + battery charging power < on-grid inverter output power".
