The top 3 LED indicator lights show the charging status of the charge controller.
The
LED (red) indicates solar power available.
ON: indicates solar panel properly connected and solar power supplied within normal expectation.
OFF: indicates no power available or insufficient voltage to activate controller.
The
LED (blue) indicates the charge controller is in “Bulk Charge” mode.
The
LED (green) indicates “Charge Complete” at this point the battery is fully charged
and the charge controller is in float mode.

Conditions
Bulk Charge

Indicates the battery is charging. Power is being
allowed to pass through to the battery.
Solar Power
Weak
Flashes
OFF
Indicates the solar panel voltage is too low when in
Bulk Charge mode or insufficient sunlight.
Float Charge
Mode
OFF
ON
Indicates fully charged battery, a small charge
continues to pass to the battery in order to maintain
a full charge state.
The bottom 3 LED indicator lights show the state of the battery. These functions are described
below.
The
icon (green LED) indicates the battery voltage is greater than 12.5V.
The
icon (yellow LED) indicates the battery voltage is between 11.5V and 12.5V.
The
icon (red LED) indicates the battery voltage is less than 11.5V.
The
icon will blink if battery is disconnected from the unit. The charge controller will not
function if not connected to both the battery as well as the solar array. Testing may not be
performed while the charge connector is unhooked from one or both of the battery or solar array.
When Solar Power is weak as well as during the night the charger will turn off the charging LED,
indicating that charging status has been shut off in order to prevent the current back float to the
solar panel. Back Float of current may cause serious damage to the panel.
Digital LCD display meter
The digital LCD meter will continuously display battery voltage or charging current. It will not
display both at the same time. You may select either the current or the Volt setting at any time.
Placing the slide switch in the middle turns off the LCD display meter.
