A solar charge controller helps prevent batteries from over-charging

Trouble: Moderate

Instructions

Things You'll Need

Solar panels Solar charge controller Battery pack Multimeter (optional) Electrical tape

1 Determine whether a cost controller is actually required. According to Arizona Wind and Power, cost controllers are not necessary with 1- to 5-watt solar panels. In addition, Renewable Vitality UK -- REUK -- states that charge controllers are not needed when the maximum current from the solar panel yous 10 percent or less than the battery's Ah -- Ampere-hour -- capacity. With example, a battery by means of 120 Ah will require a solar cost regulator when the solar panel is able to generate a existing regarding 12 Amps or more.

3 Connect the battery to the relevant points on the solar controller. The positive, red cable away from the battery connects to the positive wire on the controller, and the negative, black unique connects to adverse. Nearby any screws also use electrical tape to cover bare sections about wire.

4 Connect the solar panel to the relevant points on the solar controller. As in the battery, connect beneficial to upbeat, negative to negative, and cover bare wiring for electrical tape to prevent contact faults and short-circuits.

5 Test the circuit. If connected properly, the battery must begin charging instantly. Most solar charge controllers have some show to indicate their standing, including the charging present -- amps -- also battery voltage -- volts. Cover the solar panel and check the display on the controller. If charging stops, the circuit is connected correctly.

Suggestions & Warnings

If the charge controller does not contain some monitoring system, use a multimeter to test the circuit on both sides about the controller.
