C.V. charging voltage.
If self-defined is selected
In program 5, this program can
be set up
48V model: default 56.4V, 48.0V~58.4V Settable
24V model: default 28.2V, 24.0V~29.2V Settable

Floating charging voltage.
If self-defined is selected in
program 5, this program can be
set up
48V model: default 54.0V, 48.0V~58.4V Settable
24V model: default 27.0V, 24.0V~29.2V Settable
21
Low DC cut-off voltage.
1. If battery power is only power
source available, inverter will
shut down.
2. If PV energy and battery
power are available, inverter will
charge battery without AC
output.
3. If PV energy, battery power
and utility are all available,
inverter will transfer to line
mode and provide output power
to loads, and charge the battery
at the same time.
48V model: default 42.0V, 40.0V~48.0V Settable
24V model: default 21.0V, 20.0V~24.0V Settable
If self-defined is selected in program 5, this program can be set up.
Low DC cut-off voltage will be fixed to setting value no matter what
percentage of load is connected.

Solar power balance. When
enabled, solar input power will
be automatically adjusted
according to connected load
power.
Solar power balance
enable (Default):
If selected, solar input power will be
automatically adjusted according to the
following formula: Max. input solar power
= Max. battery charging power +
Connected load power.
Solar power balance
disable:
If selected, the solar input power will be
the same to max. battery charging power
no matter how much loads are connected.
The max. battery charging power will be
based on the setting current in program 2.
(Max. solar power = Max. battery charging
power)

AC output mode
*This setting is only
available(4KVA/5KVA) when the
inverter is in standby mode
(Switch off).
Single:
When the units are used in parallel with
single phase, please select “PAL” in
program 23.
It requires 3 inverters to support
three-phase equipment, 1 inverter in each
phase. Please refers to 3.10.5 for detailed
information.
Please select “3P1” in program 23 for the
inverters connected to L1 phase, “3P2” in
program 23 for the inverters connected to
L2 phase and “3P3” in program 23 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.
Besides, power saving function will be
automatically disabled.
Parallel:
