The PF ranges from 0.8 leading to 0.8 lagging.
Leading: the inverter is sourcing reactive power to the grid
Lagging: the inverter is sinking reactive power from the
grid.

10.7.3 Setting the Zero-export Function
Main Screen (Press ENT)→Menu (Press ×2)→Settings (Press ENT)→Input
password 111 (Press ENT)→Settings (Press ×2)→Zero-export (Press ENT)
ON: no power will be exported to the grid.
OFF: all inverter output power will be exported to the grid.
Partial: set partial of the output power to export to the grid.
Export power range:
When the existing system is disabled: 0–5000 W
When the existing system is enabled,
y
the lower limit is the rated power of the existing system;
and
y
the upper limit is (5000 W + [rated power of the existing system]).
y
the value will synchronize with the settings for retrofitting an existing system
described in section 10.7.11 .
10.7.4 Setting the Reserved Capacity (Off-grid)
Main Screen (Press ENT)→Menu (Press ×2)→Settings (Press ENT)→Input
password 111 (Press ENT)→Settings (Press ×3)→Off-grid Setting (Press ENT)
The reserved capacity is the on-grid
minimum battery discharge level. The
reserved battery capacity will be
supplied to the emergency loads in
the off-grid system
.
If the battery type is lead-acid, it is not need to set the reserved capacity.
If the off-grid function is enabled, the buzzer inside the inverter will beep
intermittently for 20 s when the battery level is lower than the threshold value
specified in the following table.
