The Solarthon MPPT Solar Charge and Discharge Controller, manufactured by Guangdong Solarthon Technology Co., Ltd., is designed to optimize the charging process of your solar panel system. With its advanced maximum power point tracking (MPPT) technology, this controller constantly monitors the power generation voltage of the solar panel in real time.
By tracking the highest voltage and current values, the Solarthon MPPT controller automatically adjusts the charging process to ensure that your battery is charged with maximum power output. This means that you can extract the maximum amount of energy from your solar array, even as the maximum power point of the panel varies with different environmental conditions.
What sets the Solarthon MPPT Solar Charge and Discharge Controller apart is its fully automatic tracking mode, which eliminates the need for user adjustment. With this controller, you can enjoy hassle-free and efficient charging for your solar panel system.
Choose from three different models - 20A, 40A, or 60A - to suit your specific power requirements. Whether you have a small residential setup or a larger commercial project, the Solarthon MPPT controller has you covered.
Invest in the Solarthon MPPT Solar Charge and Discharge Controller and experience the benefits of optimal charging efficiency for your solar panel system. Take control of your energy generation and make the most out of your solar array with Solarthon.

Introducing our pure sine wave inverters from Guangdong Solarthon Technology Co., Ltd. These inverters are designed to meet the reading habits of English-speaking natives, offering a reliable and efficient power solution for various applications.
To ensure you select the appropriate inverter for your needs, simply inform our sales team about your requirements, and they will recommend a suitable model for you.
While not absolutely required, our power inverters are essential for obtaining 220 or 230 volts AC power, allowing you to use normal AC appliances. This makes them ideal for most applications, from small RVs to cabins.
The choice between 12, 24, and 48 volt inverters depends on the voltage of your battery bank. Higher voltages result in lower currents, allowing for the use of smaller wires between your solar panel array and battery bank. It's important to ensure that all components, including solar panels, inverters, and battery banks, are compatible with the same voltage.
If any product is found to be faulty, simply send us a picture or video, and we will provide free spare parts of the PCB board for after-sale service.
