5.5 Lithium Battery Reset

This solar controller has a lithium reset feature that allows a BMS protected over discharged battery to be manually recovered with-
out having to disconnect the battery. In order for this to work there must be solar power available to power the solar controller. The
reset is performed by holding both the VOLT/AMP button and the BATTERY TYPE button for 1S.

7. TROUBLESHOOTING
7.1 PROBLEMS WITH DISPLAY
Display Reading: Blank
Time of Day: Daytime/Nighttime
Possible Causes:
Battery or fuse connection and/or solar array connection
(Daytime only) or battery or fuse connection (Nighttime only).
How to tell:
1. Check the voltage at the controller battery terminals with a voltmeter and compare with a voltage reading at the battery terminals.
2. If there is no voltage reading at the controller battery terminals, the problem is in the wiring between the battery and the controller.
If the battery voltage is lower than 6 volts the controller will not function.
3. For the solar array, repeat steps 1 and 2 substituting all battery terminals with solar array terminals.
Remedy:
Check all connections from the controller to the battery including checking for correct wire polarity. Check that all connections are clean,
tight, and secure. Ensure the battery voltage is above 6 volts.
