The Regulator uses the solar array to detect day and night. The transition to night requires the level
of solar radiation being received to be less than 2 percent. The transition back to day requires a high
solar array open-circuit voltage. Both state changes require 10 minutes of continuous transition values
before making change. These constraints avoid false transitions due to lightning or dark storm clouds.
LED Indicators:
Green LED
The green LED indicator will light whenever sunlight is available for battery charging. The green LED
will turn off at night.
Because the Regulator uses a PWM constant voltage charging process, there is usually some amount
of energy going into the battery at all times. Although the charging current falls to very low levels when
the battery reaches full charge, the green LED will continue to stay ON all day. This is to indicate that
the controller is working and that energy is available from the PV array for charging.
Red LED
The red LED is an indicator for 3 different functions:
•
Automatic low voltage load disconnect (LVD)
If the battery charge state falls below the LVD setpoint, the light will be disconnected and the red
LED will light. This indicates the controller has disconnected the load to protect the battery from
further discharge and possible damage. The red LED will turn off when the battery recovers to
about 50% of its rated capacity and the load is automatically reconnected.
•
Initial controller start-up
When the regulator is properly connected to the battery, the red LED will flash 3 times.
•
Confirm lighting control selection
When the TEST button is pressed, the red LED will confirm the lighting control option selected by
the rotary switch.
