Many qualified partners will use solar panels, in inconvenient occasions to use solar panels and batteries, play a simple role of energy storage, relatively low cost to solve the power supply. However, the output characteristics of solar cells can not be directly connected to the load and charge the battery, so it needs to be connected to the controller to be used.
Charging head network got a solar cell charge and discharge controller, with LCD screen and key control, battery charging management, automatic control, and simple configuration. Let's take a look at the interior design and materials.
A solar regulator is a device used to control the charging of solar panels and protect batteries. The main principle of the solar regulator is to monitor and regulate the output voltage and current of the solar panel to ensure the safe charging of the battery and prevent overcharging and overdischarging.
The main components of a solar regulator include electronic components, sensors, chargers and protection systems. When the solar panels are operating, the solar regulator measures the voltage and current of the battery and, based on these measurements, controls the charging and discharging process of the battery.
When the output voltage of the solar panel is higher than the voltage of the battery, the solar regulator will regulate the current to ensure that the battery does not overcharge. When the output voltage of the solar panel is lower than the voltage of the battery, the solar regulator will regulate the current to ensure that the battery can be fully charged. The solar regulator also monitors the voltage and current of the battery to prevent overdischarge and overcharge, thereby extending the life of the battery.
Solar regulators can also have other functions, such as temperature compensation, overload protection, short circuit protection and reverse protection. These features ensure the safe operation of solar panels and batteries and improve the efficiency and reliability of solar systems.
This solar regulator belongs to the basic type, support directly connect the solar panel to the battery charging, and support automatic power off, realize the automatic charging control of the battery. At the same time, the controller also supports the button control load, and the phone charging function, quite practical.
It is found that a Hetai LCD driver chip is used for the screen display and an unmarked chip is used for the whole machine control. Internal use of 34063 step-down chip for step-down, and TI LM258 operational amplifier for current sampling and amplification. Through the MOS tube to control the battery charge and discharge and load output, five MOS tube models are polished, suitable for the occasion of low requirements.
