What is the function of the solar charge controller?

The solar charge controller is mainly used to protect the battery from solar energy. It's some kind of overload protection. It protects the battery from external discharges and is a kind of low-level cargo hold. It also has protective functions such as preventing the polarization of plus and minus poles.

What are the functions of the new solar charge controller?

The new solar charge controller has the following main functions:

1. Overload protection: If the charge voltage is higher than the protective voltage, the new solar charge controllerautomatically switches off to recharge the battery. After that, when the voltage drops to the maintenance voltage, the battery switches to the maintenance charge state. If the voltage is lower than the recovery voltage, the maintenance charge shall be switched off. Enter the balance state.

2. Low load protection: If the battery voltage is lower than the protective voltage, the new solar charge controllerautomatically switches off the output to protect the battery from damage; When the battery is recharged, it can automatically restore the power supply.

3. Load current and short circuit protection: After the load current exceeds 10A or the load is short-circuited, the fuse is blown and can be used after the exchange.

4. Overvoltage protection: If the voltage is too high, the new solar charge controller automatically switches off the output to protect the electrical equipment from damage.

5. With anti-reverse charging function: Scottky diodes are used to prevent the battery charging the solar battery.

What power does the solar charge controller have?

Due to its own characteristics, the LED must be constant current or technically limited, otherwise it cannot be used normally. Conventional LED lamps are achieved by adding a drive current supply to achieve a constant current for the LED lamps, but this drive represents about 10-20% the total power of the entire lamp. For example, a LED lamp with a theoretical value of 42W plus The actual performance after driving can be approximately 46-50W. When calculating battery panel power and battery capacity, additional 10-20%must be added to cover the power consumption caused by the drive. In addition, adding additional drivers will add another link that causes errors. The solar charge controller uses a software to perform a constant current without power consumption, which shows a high stability and reduces total power consumption.

Does the solar panel need to add a solar charge controller to charge the battery?

You need to add a solar charge controller.

In addition to protecting the battery and controlling the charging mode of the battery, the solar charge controller has another function to prevent a backloading. This should prevent the battery from charging the solar module.

In the case of low solar radiation or at night the output power of the solar module is very low, the voltage low or the night voltage zero if the voltage of the solar module is lower than the battery voltage. Without a solar charge controller, the battery charges the solar module. Although the solar module can withstand the current supplied for a long time, the aging of the solar module has accelerated in the long term and burns may occur with poor quality of the solar module. Will burn out.

As a practical, convenient, green and environmentally friendly production tool, solar charge controllers are widely used worldwide. Shenzhen Sumry Electronics Co., Ltd. has worked with customers from design to completion to ensure that all technical requirements are met.
