What is a solar charge controller?

The solar charge controller is an automatic control device used in the solar power generation system to control the multi-channel solar cell array for charging the battery and the battery for power supply of the solar switching control. The solar charge controller regulates and controls the charging and discharge conditions of the battery and controls the power output of the solar cell components and the battery to the load according to the power demand of the load. It is the central control part of the entire photovoltaic power supply system.

What is an ordinary solar charge controller?

Ordinary solar charge controller is the technology of the first generation. The principle of operation is to connect the output of the solar panel directly to the battery connection and to separate it when the battery is full. Due to the internal resistance of the battery and the solar panel it is difficult to fully charge the battery few people use it.

What is the principle of solar charge controller?

Solar collectors are photovoltaic devices (the main part are semiconductor materials). After exposure to light, the photovoltaic effect generates electrical current. Due to the properties and limitations of materials and light, the generated current is also a volatile curve. If the power generated is directly charged to the battery or if the load is supplied directly with electricity, the battery and load can be slightly damaged and their life span significantly reduced. Therefore, we must first send the electricity to the solar charge controller, use a number of dedicated chip circuits to digitally adapt it, and add a multi-level charging and discharge protection to ensure the safety and life of the battery and the load. When feeding the consumer, the battery's electricity may also flow into the solar charge controller first, and after adapting it, the electricity is directed to the consumer. The purpose of this solar charge controller regulator is: one is to stabilise the discharge current; the other is to ensure that the battery is not overloaded; The third is to carry out a series of monitoring and protection measures for the load and battery.

What precautions should be taken when installing the solar charge controller?

1. Open the package and attach the solar charge controller to a suitable location (please avoid direct sunlight and wet spots).

2. First connect the battery cable (to avoid errors in the automatic identification function) and wait until the solar charge controller has completed the identification process (after the level indicator shows the battery power), then connect the solar panel cable, and finally switch off the load, when the load line is connected.

3. To ensure safety, do not use excessive load or increase the solar panel too large; Use a power supply, e.g. A power supply to replace the solar battery to charge the battery.

4. Remove the solar panel when loading and the charging current should not be too high.

5. Watch out for the plus and minus of the solar charge controller.
