The Charge Controller is equipped with 2 LED’s to indicate the battery State-of-Charge it is
currently in.
-Yellow = System charging. Current is flowing to the
battery or battery bank. Peak battery voltage may be
observed between 13.9 and 14.4 indicating the battery
is fully charged (temperature dependent).This condition
will continue for approx. 2 hours before the ‘float’ mode
engages.
-Green = Battery full. The Charge Controller has entered the ‘float’ mode. Current is still flowing
to the battery or battery bank. But, the voltage has been reduced for maintenance charging.
Battery voltage in this mode may be observed around 13.8V but could be slightly different
depending on temperature.
