Battery Over-Current
Error status LED: Flashing red. Battery status LEDs:
R/Y-G sequencing. While rare, if battery charging current
exceeds approximately 130% of the controller’s output
current rating, this fault can occur. The fault is generally
related to fast, large battery voltage transients (connecting a
very heavy or capacitive load like an inverter) that are faster
than the controller can regulate and it shuts off to protect
the circuitry. The controller will automatically re-start in 10
seconds.
Settings (DIP) Switch Changed
Error status LED: Flashing red. Battery status LEDs: R-Y-G
sequencing.
If a settings switch is changed while there is
power to the controller, the LEDs will begin sequencing and
the solar input will disconnect. The controller must be re-
started to clear the fault and begin operation with the new
settings.
Custom Settings Edit
Error status LED: Flashing red. Battery status LEDs: R-Y-G
sequencing.
A value has been modified in custom settings memory.
The controller will stop charging and indicate a fault condi-
tion. After all settings have been modified, the controller
must be reset by removing and then restoring power to the
controller. The new programmed settings will be used after
the power reset.
Firmware Update Failure
The firmware update was not successfully programmed. The
controller will not indicate the full power-up LED sequence
of G-Y-R when power to the controller is reset. Instead, the
controller will display green, and then stop on yellow. The
yellow LED will continue to be lit and the controller will not
complete start up or begin charging. Retry the firmware
update. The firmware must be successfully loaded before
the controller will start up.
