PVBEYORND MPPT Solar Charge Controller 20A 40A 60A Solar Controller MPPT 12V 24V Solar PV Regulator Fit for Lead-acid/LithiumProduct Features：

1. Using advanced dual-peak or multi-peak tracking technology, when the solar panel is shaded or part of the solar panel is damaged, the I-V curve will have multiple peaks, and the controller can still accurately track the maximum power point
2. Built-in maximum power tracking algorithm can significantly improve the energy utilization efficiency of the photovoltaic system, which is about 25% higher than the traditional PWM charging efficiency
3. Combining multiple tracking algorithms, it can accurately track the optimal working point of the I-V curve in a very short time.
4. The MPPT tracking efficiency can reach up to 99.9%
5. The circuit energy conversion efficiency is as high as 98% with the use of advanced digital power technology
6. Supports different types of battery charging programs such as colloidal batteries, sealed batteries, open batteries, lithium batteries, etc.
7. It has a current limiting charging mode. When the power of the battery panel is too large and the charging current is greater than the rated current, the controller automatically reduces the charging power to make it work at the rated charging current
8. It can support instantaneous high current startup of capacitive loads
9. Support automatic identification of battery voltage
10. It has a fault LCD display to facilitate users to determine system faults
11. Built-in over-temperature protection mechanism. When the temperature exceeds the set value of the device, the charging current decreases linearly with the temperature, thereby reducing the temperature rise of the controller and avoiding high temperature damage to the controller
12. It has a temperature compensation function, automatically adjusts the charging and discharging parameters, and increases the service life of the battery
13. Complete electronic protection function
14. It uses a metal shell with better heat dissipation performance
15. Lithium battery 0V charging function

Warm Tips:

1. Please read this manual in detail before operating the controller.

2. It is recommended that a suitable fuse or circuit breaker be installed outside the controller.

3. Before installing and adjusting the controller's wiring, be sure to disconnect the fuses or circuit breakers near the PV array and battery terminals.

4. After installation, check that all wiring connections are tight to avoid dangerous heat buildup from incorrect connections.

5. The USB charging function requires the solar charging controller to be turned on and the "ESC" button to be turned on so that the USB can provide current.

6. Currently, the 20A device is not equipped with a fan for cooling because the current is too low. Both the 40A and 60A devices are equipped with dual fans for cooling

MPPT SOLAR CHARGE CONTROLLER

Install Procedure
1、Connect 12V or 24V battery to solar controller
2、Connect 18V or 36V solar panel to solar controller
3、Connect 12V or 24V load to solar controller

Uninstall Procedure
1、uninstall solar panel from solar controller
2、uninstall load from solar controller
3、uninstall battery from solar controller

Taking the 12V system as an example, because the peak voltage (Vpp) of the solar panel is about 17V and the battery voltage is about 12V, the voltage of the solar panel is about 12V when the general charging controller is charging, and the maximum power is not fully exerted. The MPPT controller can overcome this problem and adjust the input voltage and current of the solar panel from time to time to achieve the purpose of maximum input power.
Compared with the traditional PWM controller, the MPPT controller can exert the maximum power of the solar panel, so it can provide a larger charging current. Generally speaking, MPPT can improve the energy utilization rate by about 25% compared with the PWM controller.

At the same time, due to different ambient temperature and light conditions, the maximum power point often changes. Our company's MPPT controller can adjust parameters according to different conditions at any time to keep the system near the maximum working point. The whole process is completely automatic and does not require any adjustment by the user.
