Function Of Charge Controller For Solar Panel

It does this by using a transistor to shunt the pv charging circuit.

Function of charge controller for solar panel.

Giving batteries as long of a life as possible is an important function of a charge controller. The controller directly reads the battery level and once the battery is full it knows to slow down the rate of solar charge to a float keeping is from charging the batteries past 100. Mppt or maximum power point tracking controllers are far more advanced than pwm controllers and enable the solar panel to operate at its optimum voltage for maximum power output. A charge controller or charge regulator is basically a voltage and or current regulator to keep batteries from overcharging.

Charge controllers are sold to consumers as separate devices often in conjunction with solar or wind power generators for uses such as rv boat and off the grid home battery storage systems. Maximum power point tracking mppt. It regulates the voltage and current coming from the solar panels going to the battery. Solar charge controllers regulate the energy flowing from the pv array and transfer it directly to the batteries as a dc coupled system which is the most efficient and effective manner he said.

Solar charge controller functions. The mppt solar charge controller is the sparkling star of today s solar systems these controllers truly identify the best working voltage and amperage of the solar panel exhibit and match that with the electric cell bank. The unit also comes equipped with a multi function lcd display system to display information and can also be connected to pc software or an mt50 tracker for constant monitoring. The function of a charge controller is to regulate the charge going into your battery bank from your solar panel array and prevent overcharging and reverse current flow at night.

Most 12 volt panels put out about 16 to 20 volts so if there is no regulation the batteries will be damaged from overcharging. In solar applications charge controllers may also be called solar regulators. The main purpose of the controller is to prevent the batteries from over charging.
