C.V. charging voltage.
If self-defined is selected
In program 5, this program can
be set up
24V model: default 28.2V, 24.0V~29.2V Settable
48V model: default 56.4V, 48.0V~58.4V Settable
20
Floating charging voltage.
If self-defined is selected in
program 5, this program can be
set up
24V model: default 27.0V, 24.0V~29.2V Settable
48V model: default 54.0V, 48.0V~58.4V 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.
24V model: default 21.0V, 20.0V~24.0V Settable
48V model: default 42.0V, 40.0V~48.0V 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.
22
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)
23
AC output mode
*This setting is only available
when the inverter is in standby
mode (Switch off).
Power saving function will be
automatically disabled when
in parallel operation.
Single mode
When not in parallel operation
Single phase
When the units are used in parallel
with single phase
Three phase: 3P1, 3P2, 3P3
It requires at least 3 inverters to support three-phase equipment, 1
inverter in each phase.
Please select “3P1” for the inverters connected to L1 phase, “3P2” for
the inverters connected to L2 phase and “3P3” for the inverters
connected to L3 phase.
Do NOT connect share current cable between units on different phases.
Split phase: 2P0, 2P1, 2P2
Select “2P0” for the inverters connected to L1 phase;
If connect split phase 120V/208V, select “2P1” for inverters connected
to L2 phase;
If connect split phase 120V/240V, select “2P2” for inverters connected
to L2 phase
Do NOT connect share current cable between units on different phases.
