System status contains six content:PV1/PV2/Battery/On-grid
(energy feed into or buy from the grid)and Off-grid and so on.
Press up and down to select, press "Enter" to conrm the selection,

a/b) PV1, PV2
Here you can see the voltage, current and power of the pv1 and
PV2.photovoltaic panels respectively;

c) Battery
This status shows the battery condition of the system. Including
battery voltage and battery current, Battery power, battery
capacity, battery temperature, BMS connection status. The
meaning of the sign of battery current and power: "+" means
charging; "-" means discharging.

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 SOC11%, and then return to the working mode selected by the
user.

②When 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.
(PV＜Load ,PV + Battery + Grid → Load)
③Without 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 standby state.
(PV=0 , Battery+Grid → Load)
Battery 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%.
Backup mode SOC adjustment range :30%-100%;In Backup mode,
SOC-min under off-grid condition is 10%, which cannot be modied.
The 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 necessray)
①When the power of PV is sufficent
PV will power the loads rstly, 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+Battery → Load)
③Without 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)
