AC output mode
*This setting is able to set
up only when the inverter is
in standby mode, Be sure
that on/off Switch is
in ”OFF” status.
L1 phase
When the units are operated in
3-phase application, please choose
“3PX” to define each inverter.
It is required to have at least 3
inverters or maximum 9 inverters to
support three-phase equipment. It’s
required to have at least one inverter
in each phase or it’s up to four
inverters in one phase. Please refers
to 5-2 for detailed information.
Please select “3P1” in program 28 for
the inverters connected to L1 phase,
“3P2” in program 28 for the inverters
connected to L2 phase and “3P3” in
program 28 for the inverters
connected to L3 phase.
Be sure to connect share current
cable to units which are on the same
phase.
Do NOT connect share current cable
between units on different phases.

Low DC cut-off voltage:
If battery power is only
power source available,
inverter will shut down.
If PV energy and
battery power are
available, inverter will
charge battery without
AC output.
If PV energy, battery
power and utility are all
available, inverter will
transfer to line mode
and provide output
power to loads.
3KW default setting: 21.0V
5KW default setting: 42.0V
If self-defined is selected in program 5, this program can be set
up. Setting range is from 20.0V to 27.0V for 3KW model and 40.0V
to 54.0V for 5KW model. Increment of each click is 0.1V. Low DC
cut-off voltage will be fixed to setting value no matter what
percentage of load is connected.

If “User-Defined” is selected in program 05, this program can be
set up. Setting range is from 5min to 900min. Increment of each
click is 5min. Otherwise, Keeping auto-charging time.
