If “Use-Defined” is selected in
program 02, this program can be set
up. The setting range is from 12.0V
to 15.0V. If “LIb” is selected in
program 02, this parameter is
consistent with absorption voltage.
Use-Defined(Default)
14.4V (Default)
Press "UP" or "DOWN" button to
modify, increment of each short press
is 0.1V, and after pressing for 2.5
seconds, it will charge 1V every 0.5
seconds. Once the value is achieved
15.0V, the value will jump back to12.0V.
13.6V (Default)
Press "UP" or "DOWN" button to
modify, increment of each short press
is 0.1V, and after pressing for 2.5
seconds, it will charge 1V every 0.5
seconds. Once the value is achieved
15.0V, the value will jump back to 12.0V.

If “Use-Defined” or “Lib” is selected
in program 02, this program can be
set up. The setting range is from
12.0V to 15.0V.
This program and program 05
constitute the total charging voltage.
For example, the absorption voltage is
14.4V, the setting value of program 05
is 20, and the total charging voltage
is 288V =14.4V X20.
This program and program 05
constitute the total float voltage.
For example, the float voltage is 13.6V,
the setting value of program 05 is 20,
and the total charging voltage
is 272V =13.6V X20.
If “Use-Defined” is selected, battery
charge voltage can be set up in
program 03 and 04 . If “Lib” is selected,
battery charge voltage can be set up in
program 03 .
Note：Program 03,04 and 05 is
designed for lead acid batteries, AGM
batteries and gel batteries. If lithium
batteries are used, ensure that the total
charging voltage set by the controller is
not greater than the rated charging
voltage of lithium batteries.
The setting range is from 0.1 hours to
15 hours. Press "UP"or"DOWN" button
to modify, increment of each short press
is 0.1 hours, and after pressing
for 2.5 seconds, lt wil charge 1 hours
every 0.5 seconds. It will jump back to
0.1hours after 15 is achieved.
Set the number of batteries in series
according to actual use.The 50240
model setting range is from 8 packs to
20 packs (96V~240V) and the 25384
model setting range is from 20 packs to
32 packs (240V~384V).
Note 1：One pack corresponds to 12V.
Note 2：This program applies to lead
acid batteries, AGM batteries and gel
batteries.
If 'Lib' is set in program 02, This
program should be set according to the
charging voltage of lithium battery and
make sure the controller total charging
voltage does not exceed the charging
voltage of the lithium battery. For the
calculation method of the total charging
voltage of the controller, refer to
program 03.
