WARNING Controllers should not be installed in the same enclosure as batteries as this is a corrosive environment.
Location The controller needs to be in a cool location in order to function properly. It should not be in direct sunlight, or mounted in a hot location such as the back of a solar module. The controller should be installed near the batteries, to ensure an accurate battery voltage measurement. The distance from the solar panels to the controller should not exceed 60 feet.
Wiring #12 AWG or larger wire must be used.
Solar + In is Red closest to the solar on light. The negative wires are Black (both black wires are connected together inside the controller so only one negative wire can be used if it is more convenient.)
Battery Out + Red closest to the battery
Operation The controller protects batteries from overcharging. It allows solar power to charge the battery until the battery rises to the full voltage set point. It then shuts off the solar power until the battery voltage drops by approximately 5%. Because the battery voltage fluctuates, it is normal for the charging and battery full lights to turn on and off as the battery approaches full charge. At night all lights are off to save power.
Fault Conditions All lights are off to indicate a fault during solar short circuit, solar or reversed battery. During over-temperature and battery short circuit conditions the solar light and charging light will be on with a very small charging current (approximately 30 mA). No damage will occur if the battery is removed, leaving the control directly connected to the solar module. In this case the battery full light will come on. The control will automatically limit the current if too many solar panels are put on the input.
Basic Testing Connect the control directly to a solar module (in bright sunlight) without a battery. The charging light should come on briefly, and then go out. The battery full light should then turn on steady. If this does not occur the control requires service.
Verification of the Voltage Set point - A power supply can be put on the input with the power supply current limit at or below the controller rating. The battery full light should come on when the battery voltage reaches 14.1 volts. Without a battery, the battery full light will come on at 14.4 volts on the solar input.
