series, the controller will multiply them in proportion automatically and the LCD
only displays the voltage of one battery.
Step 4: D03
Continue to press the button UP, LCD shows 10.0. This is protection value of battery
discharge. Press ENT until numbers flash, then press UP/DOWN to set up voltage that
you want, long-press ENT to confirm it.
It means it’s protected when 12V battery is less 10. 0V and there is no output power from
OU+ and OU-.
Step 5: D04
Continue to press the button UP, LCD shows 00.00 is default for acid batteries.
If it’s for lithium battery, please press ENT until numbers flash, then press UP/DOWN
to choose 01, long-press ENT to confirm it. Step 2 (D01) is no useful when you choose 01
for lithium battery. And the voltage set in step 3 (D02) will be highest charging voltage for
lithium battery.
Press ESC to exit the setting menu.
Reminder: When you set up all steps, please disconnect battery. And reconnect
controller to see if all setting is successful. When all setting is ok, then connect PV
modules to controller.
