The Solarthon MPPT Solar ChargeAnd Discharge Controller is designed to optimize the charging process of your solar panel system. With its advanced maximum power point tracking (MPPT) technology, this controller can monitor the power generation voltage of your solar panels in real time. It automatically tracks the highest voltage and current values to ensure the battery is charged with maximum power output.
Featuring a fully automatic maximum power point tracking mode, this controller does not require any user adjustment. As the maximum power point of the solar panel varies with environmental conditions, the Solarthon MPPT Solar ChargeAnd Discharge Controller ensures that the maximum energy is extracted from the solar array.
Manufactured by Guangdong Solarthon Technology Co., Ltd., this controller is available in three different models: 20A, 40A, and 60A. Choose the one that best suits your solar panel system's requirements.

Are you looking for a reliable and efficient power inverter? Look no further than the inverters from Guangdong Solarthon Technology Co., Ltd. Our inverters are designed to meet the reading habits of English-speaking natives and are perfect for both residential and commercial use.
A: Yes, all our inverters provide true pure sine wave output.
A: Our inverters normally come with a self-adapting output of 110V, 115V, 120V, 220V, 230V, and 240V, with a frequency of 50/60Hz. If you have any special requirements, our engineers are available for consultation.
A: Low frequency inverters offer various protections, strong adaptability to different environments, and reliable voltage regulation. They are more reliable compared to high frequency inverters.
A: Pure sine wave output inverters provide power quality equivalent to the public power grid, if not better. They have a low repair rate, long lifespan, no harmonic pollution, and are environmentally-friendly. On the other hand, modified sine wave output inverters can negatively affect appliances and cannot load inductive loads such as air conditioners and refrigerators. They are also not suitable for certain motor control circuits.
A: Our inverters can be used with household, office, and agricultural appliances, as well as other inductive loads such as refrigerators, air conditioners, water pumps, and more.
A: Yes, we accept OEM orders and can print your company logo on our inverters, nameplates, and packaging.
A: Simply tell us your requirements and our sales team will recommend a suitable inverter for you.
A: We offer 24-hour after-service consultancy to help you easily solve any technical problems you may encounter.
A: While a power inverter is not absolutely required for a solar energy system, it is necessary if you want to use normal AC appliances. Without an inverter, you will only have battery power and won't have access to 220 or 230 volts AC.
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 ensure that the solar panels, inverter, and battery bank all use the same voltage.
A: If any product is faulty, simply send us a picture or video and we will study it. We will provide the necessary spare parts of the PCB board free of charge for after-sale service.
