Product Description

 Solarthon MPPT Solar Charge And Discharge Controller 20A/40A/60A
The Solarthon MPPT Solar Charge And Discharge Controller, manufactured by Guangdong Solarthon Technology Co., Ltd., is designed to enhance your solar power system's efficiency.
MPPT, which stands for maximum power point tracking, is an advanced charging method that continuously monitors the power generation voltage of your solar panel. By tracking the highest voltage and current values in real time, this controller ensures that your battery is charged with the maximum power output.
With the Solarthon MPPT Solar Charge And Discharge Controller, there is no need for manual adjustments. The maximum power point tracking mode is completely automatic, adapting to the varying environmental conditions to continuously track and extract the maximum energy from your solar array.
Choose from three different models - 20A, 40A, or 60A - to suit the specific needs of your solar power system.

Product Description

 

Guangdong Solarthon Technology Co., Ltd. is proud to offer a range of high-quality inverters that are designed to meet the needs of English-speaking natives. Our inverters provide pure sine wave output, ensuring reliable and efficient performance.

 

Key Features:

 

• Pure Sine Wave Output: Our inverters produce a pure sine wave output, similar to the power grid, ensuring optimal performance for your appliances.


• Wide Voltage Range: We offer inverters with output voltages of 110V, 115V, 120V, 220V, 230V, and 240V, with a self-adapting frequency of 50/60Hz. If you have specific requirements, our engineers are available for consultation.


• Low Frequency vs. High Frequency: Our low frequency inverters offer various protections, adaptability to different environments, and reliable voltage regulation. High frequency inverters, on the other hand, may not provide the same level of reliability and adaptability.


• Pure Sine Wave vs. Modified Sine Wave: While pure sine wave inverters offer a high-quality output similar to the power grid, modified sine wave inverters can negatively impact appliances, especially those with inductive loads such as air conditioners and refrigerators. Pure sine wave inverters have a lower repair rate, longer lifespan, and are more environmentally friendly.


• Wide Range of Appliance Compatibility: Our inverters can be used with various appliances, including those found in households, offices, and agricultural settings. They are also compatible with inductive loads such as refrigerators and air conditioners.


• OEM Orders: We accept OEM orders and can print your company logo on inverters, nameplates, and packaging.


• Expert Recommendations: Our sales team is available to recommend the right inverter based on your specific requirements.


• 24/7 Technical Support: We offer 24-hour after-service consultancy to help you solve any technical problems you may encounter.


• Not Required but Highly Recommended: While a power inverter is not absolutely necessary for a solar energy system, it allows you to use normal AC appliances and provides convenience.


• Input Voltage Considerations: The choice between 12, 24, and 48-volt inverters depends on the voltage of your battery bank. Higher voltages allow for smaller wires and ensure compatibility between solar panels, inverters, and battery banks.


• Quick and Easy After-Sale Service: If any product is faulty, simply send us a picture or video, and we will study it and provide the necessary spare parts free of charge for after-sale service.
