About
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.
(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
standby state.
(PV=0 , Battery+Grid → Load )
Battery 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.
①When the power of PV is sufficient
Active Charging time period:PV will power the loads rstly, and
surplus power will feed-in to the grid. If the feed-in power has
been limited,the surplus power can charge the battery.
(PV>Load ,PV → 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 )
