Revision 1.0
A solid green LED indicates the charging source is functioning properly. A flashing green LED indicates an
error condition exists. The multi-color LED indicates the particular operating mode and the battery capacity
level.

over current, low voltage disconnect, reverse connection for solar modules, and over voltage of load. The
green LED’s flash time depends on the condition or function they are displaying; See table 5.2.
If >3s, BAT voltage is out of range
NOTE: When the controller is charging, the green LED will be solid green.
