What do you know about the solar charge controller?

The solar charge controller is a kind of intelligent surveillance barrier. It is only required if the battery has to be charged during the solar power generation process, which plays a role in monitoring the stability and protection of the battery. Solar monitoring has the advantage of supporting the monitoring of photovoltaic power generation, the monitoring of battery operation, the monitoring of load operation and the remote start of power supply.

What role does the solar charge controller play?

The most basic function of the solar charge controller is to control the battery voltage and open the circuit, i.e. if the battery voltage rises to a certain level, it stops charging the battery. The old version of the controller closes the opening or closing of the control circuit mechanically and stops or starts the energy supplied from the power supply to the battery.

In most photovoltaic systems, a solar charge controller is used to protect the battery from overload or deep discharge. An overload can vaporize the electrolyte in the battery and cause malfunctions, while a low charge of the battery can lead to premature battery failure. Overloading and deep loading can damage the load. Therefore, the solar charge controller is one of the core components of the photovoltaic power plant and the main component of the BOS (Balance of System).

What is the charging mode of the solar charge controller?

Loading

The charging mode of the conventional solar charge controller consists of copying the three-stage charging process of the mains charger, namely the three levels of constant current, constant voltage and maintenance charge. Since the energy of the power grid is infinite, the battery will explode directly and damage if the constant current charge is not carried out using the constant current charging procedure of the grid controller. Scientifically speaking, this results in a waste of charging efficiency when the power generated by the battery panel is greater than the power limited by the first stage of the controller. The MCT charging method consists of tracking the maximum current of the battery board without causing waste. By recording the battery voltage and calculating the temperature compensation value, when the battery voltage is close to the peak value, the pulse-type storage charging procedure is used to fully charge the battery. The solar charge controller also prevents the battery from overloading.

What are the new developments of the current new solar charge controller?

1. The solar charge controller has a lightning protection function: In the event of a lightning strike, the Varistor can prevent the lightning strike and protect the controller from damage.

2. Solar battery pollution protection: The polarity connection of the solar battery "+" "+"-"is inverse, it can be used continuously after the correction.

3. Battery Pollution Protection: The batteries "+" and "-" are plugged in, the fuse is blown and the solar charge controller can be used after the exchange.

4. Battery idling protection: If the battery is open and the solar battery is charged normally, the solar charge controller limits the voltage at the load to ensure that the load is not powerless and no action is taken.

5. The solar charge controller has a temperature compensation function.

The solar charge controller can effectively reduce the loss of battery usage. Shenzhen Sumry Electronics Co., Ltd. strives to offer high quality products at reasonable prices, efficient production times and the most professional customer service.
