Description
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 Charging or Discharge time period: PV will power the
battery. When the battery is fully charged, PV will power the load,
and 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＞Battery charge, PV →Battery→Load → Grid)
② When the power of PV is insufficient
Active Charging time period: PV will power the battery and the
remaining power will be taken from the grid when PV is not
enough. PV and grid power will charge the battery until it reaches
the set value. And then PV will power the load and the remaining
power will be taken from the grid when PV is not enough. The
battery will not discharge at this time.
(PV＜Battery charge, PV + Grid → Battery)
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 rstly. If the battery power is not enough ,the remaining
power will be taken from the grid. The inverter will enter into the
idle mode.
(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
The Feed-in priority mode is suitable for areas with high feed-in
subsidies, but has feed-in power limitation.
①When the power of PV is sufficient
Active Charging time period: PV power the battery to the set value,
and then power the load, and sell the surplus 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＞Battery, PV→Battery→Load→Grid → Battery)
Active Discharge time period: PV will power the loads rstly, and
surplus power will feed-in to the grid.
(PV＜Load, PV → Load → Grid )

②When the power of PV is insufficient
Active Charging time period: PV will power the battery and the remaining
power will be taken from the grid when PV is not enough. PV and grid power
will charge the battery until it reaches the set value. And then PV will power
the load and the remaining power will be taken from the grid when PV is not
enough. The battery will not discharge.
(PV＜ Battery charge, PV + Grid → Battery)
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 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
rstly. If the battery power is not enough, the remaining power will be
taken from the grid. The inverter will enter into the idle mode.
(PV=0, Battery+Grid → Load)
Battery min SOC can be set:10%-100%.;
Charge battery to min SOC can be set:10%-100%.
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. (Users' setting) 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 EPS(Off-grid) mode is used when the power grid is off. System will
provides emergency power through PV and batteries to supply power to
the household loads. (Battery is necessary)
①When the power of PV is sufficient
PV will power the loads rstly, and surplus power will charge to the battery.
(PV＞Load , PV → Load → Battery)
②When the power of PV is insufficient
The remaining power will be taken from the battery.
(PV＜Load, PV+Battery → Load → Battery)
③Without PV power
The battery will power the emergency loads until the battery reached the
min SOC, then the inverter will enter into the idle mode.
(PV=0 , Battery → Load)
EPS(off-grid) SOC-min condition is adjustable within the range of
1 0%-25%;
Note: in the case of grid connection, all working modes work normally when the battery
SOC >5%. When the Min SOC of the system - the actual SOC of the battery > 5%, PV or
Grid will force the battery to charge to Min SOC +1%, and then return to the normal
working mode set by the user.
Manual mode, there are three options to choose from: forced
charging, forced discharge, stop charging and discharging (grid-
connected power).
Note: when the actual SOC of the battery is ≤ Min SOC, if the mains power is lost,
the inverter will not enter the EPS (Off-grid) mode. The inverter is in EPS Waiting
state, at which time the PV will charge the battery. When the battery capacity
reaches 31%, the machine will automatically enter EPS (Off-grid) mode.
