A solar charge controller is basically a voltage or current controller. This device plays a critical role in solar system to protect the battery from overcharging.

The major role of a solar charge controller can be broadly listed into three functions.

  • Plays a critical role in charging the battery with right power.
  • Displays an indication when the battery is full to make informed decisions.
  • Closely monitors the battery voltage and appropriately cuts off the load when the voltage is low.

The function of the Solar Charge Controller:

The most essential charge controller basically controls the device voltage and opens the circuit, halting the charging, when the battery voltage ascents to a certain level. More charge controllers utilized a mechanical relay to open or shut the circuit, halting or beginning power heading off to the electric storage devices.

Generally, solar power systems utilize 12V of batteries. Solar panels can convey much more voltage than is obliged to charge the battery. The charge voltage could be kept at the best level while the time needed to completely charge the electric storage devices is lessened. This permits the solar systems to work optimally constantly. By running higher voltage in the wires from the solar panels to the charge controller, power dissipation in the wires is diminished fundamentally.

The solar charge controllers can also control the reverse power flow. The charge controllers can distinguish when no power is originating from the solar panels and open the circuit separating the solar panels from the battery devices and halting the reverse current flow.
