Mode selection, there are 4 working modes to choose from.
Name Description
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 loads
rstly, 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 Charging time period: PV will power the loads rstly ,the
remaining power will be taken from the grid , the battery will not
discharge at this time.
Self Use
(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 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 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: First, PV supply power to the load,
then charge the battery to the set capacity, and then sell the
Feed-in
power to the grid. If the local grid company limits the
priority
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 rstly, and
surplus power will feed-in to the grid.
(PV＜Load, PV → Load → Grid )
