Description
[08] GEL
default
Colloidal lead-acid battery; constant-voltage
charge voltage: 28.4V, floating charge voltage:
27.6V.
[08]
LF07/LF08/LF09
Lithium iron phosphate battery LF07/LF08/LF09,
corresponding to 7 strings ,8 strings and 9
strings of lithium iron phosphate battery; for 7
strings, default constant-voltage charge voltage
is 24.8V; for 8 strings, default constant-voltage
charge voltage is 28.4V; for 9 strings, default
constant-voltage charge voltage is 31.8V; allow
adjustable.
[08] NCA
Ternary lithium battery; the default constant-
voltage charge voltage is 28.4V, which is
adjustable.
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
