Product Overview
2.7.2 Feed-in Priority (Priority: Loads > Grid > Battery)
The feed-in priority mode is suitable for areas with high feed-in subsidies. The power
generated from PV is directed towards supplying the loads. Any excess power beyond the
load requirements will be fed into the grid.

Feed-in Priority
(Assuming peak power from 7:00 to 23:00)
Idea: Peak electricity selling, low valley charging

Time period Inverter working status
Forced charging
period
• Charge the battery first untill the battery SOC reaches the
specified Charge battery to value. You can configure the
inverter to either draw power from the grid or not.
Allowed discharging
period
PV is sufficient
(PV
→
load
→
grid)
• The power generated from PV is directed towards supplying
the loads. Any excess power beyond the load requirements will
be fed into the grid.
PV is insufficient
(PV+battery
→
load)
• PV and battery supply power to the load at the same time, and
once the battery capacity reaches Min SOC, it automatically
ceases discharging.
Note:
Charge battery to: The battery SOC charged from grid. 50% by default, range is 10%~100%.
Min SOC: Minimum SOC of the battery under grid connection. 10% by default, range is
10%~100%.
