Solar Cells will produce electricity in direct current. The voltage and current produced will be varied according to the intensity of the light. When the system is designed to be connected to the battery to store or back up the electrical energy produced. It was found that the intensity of light falling on the solar panel was not uniform according to the environment and time. Some of the currents and voltages produced by some solar panels are too high and some of them are low, resulting in unreliable voltage and current. Therefore charging the battery directly to the battery is not as effective as it should be. And the key is to shorten the life of the battery. Or worse Because the voltage produced by solar cells sometimes exceeds the battery voltage. As a result, the charger is designed to make the charging of the solar cells more efficient. It also protects the battery from overcharging.

The solar charge controller has 2 type of charger.

1. PWM (Pulse Width Modulation) The principle is to control the frequency of the electric wave from the solar panel to a fixed. To save energy And it can control the battery to power it. The battery does not deteriorate. A function indicator that connects to devices such as the solar panel / battery charge level (full / medium power or low power) / DC power supply. DC Electrical Appliances The circuit. Automatic shut off In case of low battery To protect the battery from overcharging / Over Discharge Protection.

The PWM Solar Charge Controller is available in different sizes according to the following operating levels: 10A 20A 30A 40A 50A 60A and selectable according to input voltage: 12V 24V 48V or 96V

2. MPPT (Maximum Power Point Tracking) The principle of this function is to have a microprocessor. Or catcher Controlling electrical signals from solar panels. Compared to the current in the battery. And choose the highest electrical signal from the panel to fully charge the battery at all times. So worry when using this device. The outside sun is not stable in the morning / evening or dusk. Before / after rain

The MPPT Solar Charge Controller is available in different sizes according to the following usage levels: 10A 20A 30A 40A 50A 60A and selectable according to input voltage: 12V 24V 48V or 96V
