Page 23 Product Overview Work 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 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 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 Time period Inverter working status Its working logic is basically the same as that in self use mode. The difference lies in: • In self use mode, the battery goes into hibernation when PV input is not available and the battery SOC reaches Min SOC (on-grid min SOC).
Page 28 Product Overview 2.7.4 Peak Shaving Mode Peak shaving mode is set for adjusting power consumption in peak hours. Through intelligent control, it is to ensure that the battery charges during off-peak hours and discharges during peak hours. Peak Shaving Mode Power (Assuming peak power from 7:00 to 9:00 and from 18:00 to 23:00) Battery powers the load...
Page 29 Product Overview settable range is 0-60000 W. PeakLimits: The limit of power of loads taking power from the grid side. 0 W by default, the settable range: 0-60000 W. Reserved SOC: The lowest battery SOC set for a peak shaving period. 50% by default, the settable range is 10~100%.
Page 30 Product Overview 2.7.6 EPS Mode (Priority: Loads>Battery) During power failure, the system will supply constant power to the EPS loads with the power from the PV and battery. It is important to ensure that the total power of EPS loads should not exceed the maximum output power of the battery.
Page 31 Product Overview 2.7.7 Manual Mode Manual mode is only for the qualified debugging and maintenance personnel. It includes Forced Discharge, Forced Charge and Stop Charging. The mode will automatically exit after it has been working for 6 hours. 2.7.8 Export Control Export control is to control the amount of electricity exported from the PV to the grid.

Page 182 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 terminal.
Page 183 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".
