2.3 Work Modes
X1-Hybrid G4 series, can be based on different needs, there are a variety of models.
Self Use
The self-use mode is suitable for areas with low feed-in
subsidies and high electricity prices.
① When the power of PV is sufficient
Active Charge or Discharge time period: PV will power the
loads firstly, and surplus power will charge to the battery.
If the battery is fully charged, then sell the surplus power to
the grid;(The inverter will limit the output if Feed-in limit or
zero feed-in is needed)
(PV＞Load, PV →Load→Battery → Grid)
② When the power of PV is insufficient
Active Charge time period: PV will power the loads firstly ,
the remaining power will be taken from the grid, the battery
will not discharge at this time.
(PV＜Load, PV + Grid → Load)
Active Discharge time period: PV+BAT will power the loads
together. If the power is still not enough, the remaining
power will be taken from the grid.
(PV＜Load, PV + Battery + Grid → Load)
③ Without PV power
Active Charging time period: The grid supplies the loads
and also can charge the battery;
(PV=0, Grid → Load + Battery)
Active Discharge time period: The battery will power the
home loads firstly. If the battery power is not enough ,the
remaining power will be taken from the grid. The inverter
will enter into the standby state.
(PV=0, Battery+Grid → Load )
Battery min SOC can be set:10%-100%
Charge battery to min SOC can be set:10%-100%
Feed-in priority
①When the power of PV is sufficient
PV will power the loads firstly, and surplus power
will charge to the battery.
(PV＞Load, PV → Load → Battery)
②When the power of PV is insufficient
The remaining power will be taken from the battery.
(PV＜Load, PV → Load)
③ Without PV power
The battery will power the emergency loads until
the battery reached the min SOC, then the inverter
will enter an idle mode.
(PV=0, Battery → Load)
EPS(off-grid) SOC-min condition is adjustable within
the range of 10%-25%;
EPS(Off-grid)
Backup mode
The back-up mode is suitable for areas with
frequent power outages.
Same working logic with “Self-use” mode. This
mode will maintain the battery capacity at a
relatively high level, to ensure that the
emergency loads can be used when the grid
is off. Customers no need to worry about the
battery capacity.
Battery min SOC can be set: 30%-100%.
Charge battery to min SOC can be set: 30%-100%.

The Feed-in priority mode is suitable for areas with high
feed-in subsidies, but has feed-in power limitation.
①When the power of PV is sufficient
Active Charge time period: First, PV supply power to
the load, then charge the battery to the set capacity,
and then sell the power to the grid. If the local grid
company limits the grid-connected power of the inverter,
the excess energy continues to charge the battery.
(PV＞Load, PV → Load → Battery→ Grid → Battery)
Active Discharge time period:PV will power the loads firstly,
and surplus power will feed-in to the grid.
(PV＞Load, PV → Load → Grid )
②When the power of PV is insufficient
Active Charge time period: PV will power the loads firstly,
the remaining power will be taken from the grid. The battery
will not discharge.
(PV＜Load, PV + Grid → Load)
Discharge time period: PV+BAT will power the loads together.
If the power is still not enough, the remaining power will be
taken from the grid.
(PV＜Load, PV + Battery + Grid → Load)
③Without PV power
Active Charge time period: The grid will power
the home loads and also charge the battery;
(PV=0, Grid → Load +Battery)
Active Discharge time period: The battery will
power the home loads firstly. If the battery power
is not enough, the remaining power will be taken
from the grid. The inverter will enter into the
standby state.
(PV=0, Battery+Grid → Load)
Battery min SOC can be set:10%-100%
Charge battery to min SOC can be set:10%-100%

In case of power failure, the system will power EPS
loads through PV and battery.
(Battery must be installed, and EPS loads shall not
exceed battery's max. output power.)
Notice: In the case of grid connection, all working modes work normally when the battery
SOC >5%. When the battery charge rate is below 5%, the PV or Grid will first charge the
