The Solarthon MPPT Solar Charge and Discharge Controller is designed to maximize the power output of your solar panel system. With its advanced maximum power point tracking (MPPT) technology, this controller continuously monitors the voltage and current of your solar panel in real time. It automatically tracks and adjusts the charging parameters to ensure that your battery is charged with the maximum power output.
The MPPT mode of this controller is completely automatic, eliminating the need for user adjustments. It constantly tracks the maximum power point of the solar panel, which varies with environmental conditions, to extract the maximum energy from your solar array. This means that you can enjoy the full potential of your solar panel system and maximize your energy savings.
Manufactured by Guangdong Solarthon Technology Co., Ltd., a leading company in the solar energy industry, this MPPT Solar Charge and Discharge Controller is built to deliver high performance and reliability. Choose from three different models: 20A, 40A, and 60A, depending on your specific energy needs.

Are you looking for a reliable and efficient inverter for your power needs? Look no further! Guangdong Solarthon Technology Co., Ltd. offers a range of pure sine wave inverters that are designed to meet the reading habits of English-speaking natives.
Not sure which inverter suits your needs? Simply tell us your requirements, and our sales team will recommend the most suitable inverter for you.
At Guangdong Solarthon Technology Co., Ltd., we believe in providing top-notch customer service. Our dedicated support team is available 24/7 to assist you with any technical problems you may encounter.
A pure sine wave output inverter provides power that is as good as the public power grid, if not better. It offers a long lifespan, low repair rates, and protects your appliances. On the other hand, a modified sine wave inverter can negatively impact appliances and may not be suitable for certain motor control circuits or inductive loads like air conditioners and refrigerators.
Our pure sine wave inverters are designed to work seamlessly with household, office, and agricultural appliances, as well as other inductive loads.
We offer OEM orders, allowing you to add your company logo to our inverters, nameplates, and packaging.
Our inverters are available in 12V, 24V, and 48V options. Choosing the right voltage is essential for efficient power transmission and compatibility between the solar panels, inverter, and battery bank.
In case of any product faults, simply send us pictures or videos, and we will study the issue. We offer free spare parts of PCB boards for after-sale service.
For more information about our pure sine wave inverters, please visit our website or contact us directly. Thank you!
