7. Use
• When the solar charge regulator is initialized, the display shows:
S O L A R
• At any time, press the OK button to see the battery voltage, the charging current and
the loading current sequentially (interval ±4s):
B a t t e r y x x . x V
C h a r g e x x . x A
L o a d x x . x A
• Press the MENU button repeatedly to scroll through the menus:
1. Show the current system temperature
T e m p e r a t u r e x x C
2. Show the charging current
C h a r g e 0 0 0 0 0 0 A h
3. Show the discharging current
L o a d 0 0 0 0 0 0 A h
4. Show the battery capacity
B a t t e r y S O C x x %
5. Check/set up the charge-off voltage limit (use the and/or buttons to
change the value)
C h a r g e o f f 1 3 . 8 V
6. Check/set up the load-off voltage limit (use the and/or buttons to change
the value)
L o a d o f f 1 0 . 5 V
7. Check/set up the load-on voltage limit (use the and/or buttons to change
the value)
L o a d o n 1 2 . 5 V
• To reset the SOL30UC2 to default values, press and hold the MENU button for ±5s.
8. Troubleshooting
Problem: load indicator [2] off, display shows “Battery low” and load stops working.
Reason: low battery voltage.
Possible solutions:
• Remove load and press the RESET button. When battery is fully charged, reconnect
the load.
• Increase the number of solar panels or change the battery to match the connected
load.
Problem: load indicator [2] off, display shows “overload” and load stops working.
Reason: system overloaded.
Possible solutions: remove as much load as necessary and press the RESET button.
Problem: load indicator [2] off, display shows “short circuit” and load stops working.
Reason: short circuit inside the load.
Possible solutions:
• Resolve the short circuit problem on the load and press the RESET button.
