How does MPPT solar controller & Inverter Charger work?

MPPT solar charge controller

To charge the battery, the output voltage of the solar panel must be higher than the current voltage of the battery, if the voltage of the solar panel is lower than the voltage of the battery, the output current will be close to 0. Therefore, for safety reasons, when the solar panel is manufactured, the peak voltage (Vpp) of the solar panel is about 17V, which is set based on the standard when the ambient temperature is 25°C. When the weather is very hot, the peak voltage Vpp of the solar panel will drop to about 15V, but in cold weather, the peak voltage Vpp of the solar energy can reach 18V.

Let's go back and compare the difference between MPPT solar controller and traditional solar controller. The traditional solar charge and discharge controller is a bit like a manual gearbox. When the engine speed increases, if the gear of the gearbox is not increased accordingly, it will inevitably affect the speed of the vehicle. But for the MPPT solar controller, the charging parameters are set before leaving the factory, that is to say, the MPPT controller will track the maximum power point in the solar panel in real time to exert the maximum effect of the solar panel. The higher the voltage, the more power can be output through maximum power tracking, which improves the charging efficiency. In theory, the solar power generation system using MPPT controller will increase the efficiency by 50% compared with the traditional one, but according to our actual test, due to the influence of the surrounding environment and various energy losses, the final efficiency can also be increased by 20%-30% .

Solar Inverter

The working principle of the inverter is actually a process of converting low voltage DC to high voltage AC. The DC voltage is divided into two channels: one is to supply power to the front-level IC to generate a KHZ level control signal, and the other is to the front-level power tube. Below are the 3 steps in the conversion from low voltage DC to high voltage AC and the resulting current (voltage) produced by each step:

Step 1: The control signal drives the power tube to switch continuously, so that the primary of the high-frequency transformer generates low-voltage high-frequency alternating current (produces low-voltage, high-frequency alternating current).

Step 2: Output high-frequency alternating current through the high-frequency transformer, and then output a high-frequency hundreds of V direct current through the full-bridge rectification of the fast recovery diode to the power tube of the latter stage (producing alternating current with high voltage and high frequency).

Step 3: The post-stage IC generates a control signal of about 50HZ to control the work of the post-stage power tube, and outputs 220V 50HZ alternating current (generates 220V 50HZ alternating current).
