BATTERY CHARGE LEVEL INDICATOR L.E.Ds
The bottom 3 LED indicator lights show the batteries level of charge.
The green LED indicates the battery voltage is greater than 12.5V.
The yellow LED indicates the battery voltage is between 11.5V and 12.5V.
The red LED indicates the battery voltage is less than 11.5V.
The red LED 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 batteries or
solar array.
When Solar Power is weak as well as during the night the charger will turn off the
charging LED.

MAINTENANCE

The following maintenance is recommended to be performed every three months:
1. Ensure all wire connections are sound and free from corrosion. Tighten terminal block screws
for both the solar array as well as the battery terminals.
2. Visually check the solar array and battery wiring for signs of overheating, damage, and
cracking. Replace any wires showing wear with new wires of the same gauge.
3. Verify each LED status to ensure match with specifications using a voltmeter.
