Description
[09]
Battery boost
charge voltage
28.4V
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
120
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
28.4V
Floating charge voltage, setting
range: 24V~29.2V, step: 0.2V, valid
when battery type is user-defined.
[12]
Battery over
discharge voltage
(delay off)
23.4V
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
5S
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
24.8V
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
