The type of solar charge controller

Now the solar charge controller can be divided into five types: parallel solar controller, tandem solar controller, PWM solar controller, intelligent solar controller, MPPT solar controller.

1,parallel solar controller

Parallel solar controller, when the battery is full, the use of electronic components to Xing array output shunt to Zhou We Tong parallel resistor or power module up, and then consumed in the form of heat. Parallel controller is generally used for small, low-power systems.

2,tandem solar controller

The tandem solar controller uses a mechanical relay to control the charging process and cut off the PV array at night. It is generally used for higher power systems and the capacity of the relay determines the power rating of the charge controller.

3, MPPT solar controller

MPPT solar controller (maximum power point tracking), the solar cell voltage and current detection multiplied by the power, and then determine whether the maximum output power of solar cells at this time.

4, PWM solar controller

PWM Solar Controller (Pulse Width Modulation), which switches the PV array inputs in PWM pulses. When the battery tends to fill, the pulse frequency and time shortened. This charge process to form a more complete state of charge, it can make the battery more long-term use,

5, intelligent solar controller

Intelligent solar controller, based on the remote power parameters of the photovoltaic system for high-speed real-time acquisition, and by the software program in accordance with certain control of single or multi-channel photovoltaic array cut off and connected to the controller.
