When the power of PV is insufficient
Active Charging time period: PV will power the loads rstly, 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.

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

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)
When the power of PV is sufficient
①

PV will power the loads rstly, and surplus power will charge to the
battery.(PV＞Load , PV → Load → Battery)
EPS
②
When the power of PV is insufficient
(Off-grid)
The remaining power will be taken from the battery.
(PV＜Load, PV+Battery → Load → Battery)
Without PV power
③

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 battery charge rate is below 5%, the PV or Grid will first
charge the battery SOC
11%, and then return to the working mode selected by the
Manual mode, there are three options to choose from: forced charging, forced
discharge, stop charging and discharging (grid-connected 0 power).
