The Solarthon MPPT Solar Charge And Discharge Controller, developed by Guangdong Solarthon Technology Co., Ltd., is a state-of-the-art charging device designed to maximize the power output of your solar panel system.
The MPPT technology enables the controller to monitor the real-time power generation voltage of your solar panel. By automatically tracking the highest voltage and current values, this controller ensures that your system charges the battery with the maximum power output possible.
With the Solarthon MPPT Solar Charge And Discharge Controller, there's no need for user adjustment. The controller's maximum power point tracking mode operates completely automatically. It continuously tracks the solar panel's maximum power point, adjusting to changes in environmental conditions. This guarantees the extraction of the maximum amount of energy from your solar array.
Choose the appropriate model based on your power requirements and enjoy efficient and reliable solar charging with the Solarthon MPPT Solar Charge And Discharge Controller.

Product Description:
Q1: Are your inverters pure sine wave output?
A: Yes, all our inverters provide a true pure sine wave output.
Q2: What kind of output can your inverters produce?
A: Normally, we produce inverters with self-adapting 110V, 115V, 120V, 220V, 230V, and 240V outputs at 50/60Hz. If you have special requirements, please consult with our engineers.
Q3: What's the difference between low frequency and high frequency inverters?
A: Low frequency inverters offer various protections, strong adaptability to different environments, and reliable voltage regulation.
Q4: What's the difference between pure sine wave inverters and modified sine wave inverters?
A: Pure sine wave output inverters provide power output that is as good as the public power grid, if not better. They have a low repair rate, long lifespan, no harmonic pollution, and are environmentally friendly. Modified sine wave output inverters, on the other hand, can have a negative impact on appliances and are not suitable for loading inductive loads such as air conditioners and refrigerators. Certain motor control circuits may also be incompatible with modified sine wave inverters.
Q5: What appliances can your inverters load?
A: Our inverters can be used with household, office, agricultural appliances, and other inductive loads such as refrigerators, air conditioners, water pumps, etc.
Q6: Can you print our company logo on inverters, nameplates, and packaging?
A: Yes, we accept OEM orders and can customize the products with your company logo.
Q7: How do I choose the right inverter?
A: Simply tell us your requirements, and our sales team will recommend a suitable inverter for you.
Q8: How do I solve technical problems?
A: We provide 24-hour after-service consultancy to help you easily solve any technical problems you may encounter.
Q9: Do I need a power inverter?
A: Technically, no. A power inverter is not absolutely required in a solar energy system. However, without an inverter, you will not have access to 220 or 230 volts AC power and will have to rely solely on battery power. While this may be acceptable for small RVs or cabins, most people prefer to use normal AC appliances.
Q10: What's the difference between 12, 24, and 48 volt inverters?
A: The voltage refers to the input voltage from the battery bank. Choosing a higher voltage allows for lower current, which means you can use smaller wires between your solar panel array and battery bank. It is important to note that when deciding on a system voltage, the solar panels, inverter, and battery bank must all use the same voltage.
Q11: What should I do if the product is broken?
A: If any product is faulty, please send us a picture or video, and we will study it and provide the necessary spare parts of the PCB board free of charge for after-sales service.
