7.3 Menu Conf (System module settings)

In this menu, you can configure the system modules, including battery type, battery nominal capacity, low voltage
protection mode and activate pre-set configurations. Press ▲ to enter the menu.
Battery type selection: Press the OK button to enter the menu, you may toggle between
Battery type
Gel to liquid electrolyte.
Liquid
Possibilities for programming: Liquid, Gel (Default: Liquid).
Battery nominal capacity: Press the OK button to enter the menu, press arrow keys ▲▼for
changing the nominal capacity and press OK for entering the new value.
Nominal capacity
300Ah Possibilities for programming: 10Ah~9990Ah (Default: 300Ah).
Note: The nominal capacity must be consistent with the actual battery capacity when the
controller is installed.
Low voltage protection mode (Soc or voltage control) settings: Press the OK button to enter
Regulation the menu, and switch with the keys ▲ ▼ between SOC and Voltage.
Soc
Possibilities for programming: Soc, Voltage (Default: Soc).
Factory pre-set: Press the OK button to enter the menu, and press the
Factory adjust
"OK + MENU" button simultaneously to reset the solar charge controller.
Press OK+MENU
Note: If you press "OK+MENU", all settings and values will be reset and the execution will
be confirmed by "Done".

7.4 Menu Prog (System parameter settings)

In this menu you can set the charging parameters, Day/Nigh threshold, LVD and LVR data.
Press ▼ to enter the menu.
Note: We have tried to insure that the values are limited within ranges that do not damage the battery immediately.
However, certain skills are needed as far as battery behaviour is concerned to prevent long-term damage or poor
system performance. If you are unsure about any of these settings, please refer to your authorised dealer or leave
the pre-set configurations as they are.
Float voltage settings: Press the OK button to enter the menu, press ▲ ▼ to change the
Float charge
13.7V value.
Note: The float voltage serves for maintaining the charge in the battery for long periods and
preventing self-discharge. This voltage should not be too high, since this may lead to
permanent gassing, which damages the battery. Maximum values are stated on the battery
data sheet of your battery. For most types of liquid battery, this float value is 13.7V/27.4V.
Possibilities for programming: 13.0~14.5V/26.0V~29.0V (Default: 13.7V/27.4V).
Boost voltage settings: Press the OK button to enter the menu, press ▲ ▼ to change the
Boost charge
value.
14.5V
Possibilities for programming: 14.0~15.0V/28.0V~30.0V (Default: 14.5V/29.0V).
