Product Description
Thank you for choosing MPPT solar charge controller!
This series of products has high conversion efficiency, soft LCD backlight display, efficient MPPT algorithm, neat internal structure and beautiful appearance design. With the continuous optimization of products, this series of products has its unique advantages:
• Various sampling data are visually displayed on the screen, which is convenient for users to check.
• Input PV voltage 150V, suitable for various common solar panel specifications.
• Use ultra-low-power power chips to reduce static standby energy consumption and nighttime energy loss.
• Continuously optimize the design, high cost performance.
Features
• Efficient MPPT controller algorithm, MPPT efficiency is not less than 99.5%, and the conversion efficiency of the whole machine is as high as 98%.
• Charging method: three-stage charge (constant current, constant voltage, floating charge), which can effectively prolong the life of the battery.
• LOAD mode includes normally open/normally closed mode, light control mode, dual-period control mode, light control-fixed time control mode.
• Automatic identification of battery system voltage.
• Customers can choose to charge 3 types of commonly used batteries (sealed lead-acid battery, colloidal lead-acid battery, open lead-acid battery), and can customize parameters to charge other types of batteries.
• With current-limiting charging function, when the user's battery board power is too large, the controller automatically maintains the charging power, and the charging current will not exceed the rated value.
• With high-definition LCD display function, you can check the operating data and working status of the equipment, and can support the modification of the display parameters of the controller.
• RS485 communication, can provide communication protocol, which is convenient for customers to integrate management and secondary development.
• Support PC software monitoring, support WIFI module expansion to realize app cloud monitoring.
• The product has passed CE, ROHS, FCC certification; can cooperate with customers to pass various certifications.
• The normal warranty period is three years, and the extended warranty service of 3~10 years can be provided.
