Parameter
no.
Parameter
name
Settings
Description
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] 55.2V
default
Floating charge voltage, setting range: 48V~58.4V,
step: 0.4V, valid when battery type is user-defined.
12
Battery over
discharge
voltage (delay
off)
[12] 42V
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 40V~48V, with a step of 0.4V. 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] 44V
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 40V~52V, with a step of 0.4V. It is
valid for user-defined battery and lithium battery.
15
Battery
discharge limit
voltage
[15] 40V
default
Battery discharge limit voltage; when the battery
voltage is lower than the point, the output is turned
off immediately; the setting range is 40V~52V, with a
step of 0.4V. It is valid for user-defined battery and
lithium battery.
16
Battery
equalization
enable
[16] DIS
Equalizing charge is disabled
[16] ENA
default
Equalizing charge is enabled, only valid for vented
lead-acid battery and sealed lead-acid battery
17
Battery
equalization
voltage
[17] 58.4V
default
Equalizing charge voltage; setting range: 48V~58.4V,
with a step of 0.4V; valid for vented lead-acid battery
and sealed lead-acid battery
