Parameter
name
Settings
Description
09
Battery boost
charge
voltage
[09] 28.8V
default
Boost charge voltage setting; the setting range
is 24V~29.2V, with step of 0.2V; it is valid for
user-defined battery and lithium battery.
10
Battery boost
charge time
[10] 120
default
Boost charge maximum time setting, which
means the maximum charging time to reach
the set voltage of parameter [09] during
constant-voltage charging. The setting range is
5min~900min, with a step of 5 minutes. It is
valid for user-defined battery and lithium
battery.
11
Battery
floating
charge
voltage
[11] 27.6V
default
Floating charge voltage, setting range:
24V~229.V, step: 0.2V, valid when battery type
is user-defined.
12
Battery over
discharge
voltage (delay
off)
[12] 21V
default
Over-discharge voltage; when the battery
voltage is lower than this judgment point, delay
the time set by parameter [13] and turn off
inverter output. Setting range is 20V~24V, with
a step of 0.2V. It is valid for user-defined
battery and lithium battery.
13
Battery over
discharge
delay time
[13] 5S
default
Over-discharge delay time; when the battery
voltage is lower than the parameter [12], the
inverter output will be turned off after the time
set by this parameter is delayed. The setting
range is 5S~55S, with a step of 5S. It is valid for
user-defined battery and lithium battery.
14
Battery under
voltage alarm
[14] 22V
default
Battery undervoltage alarm point; when the
battery voltage is lower than the point, an
undervoltage alarm is given, and the output is
not turned off; the setting range is 20V~26V,
with a step of 0.2V. It is valid for user-defined
battery and lithium battery.
15
Battery
discharge
limit voltage
[15] 20V
default
Battery discharge limit voltage; when the
battery voltage is lower than the point, the
output is turned off immediately; the setting
range is 20V~26V, with a step of 0.2V. It is valid
for user-defined battery and lithium battery.
