The Solarthon MPPT Solar Charge And Discharge Controller, manufactured by Guangdong Solarthon Technology Co., Ltd., is a cutting-edge device designed to optimize the charging process of solar panels. With its advanced maximum power point tracking (MPPT) technology, this controller constantly monitors the power generation voltage of the solar panel in real time. It then automatically tracks the highest voltage and current values, ensuring that the battery is charged with maximum power output.
The MPPT mode of this controller is fully automatic, eliminating the need for user adjustment. By continuously tracking the maximum power point of the solar panel, this controller enables the extraction of maximum energy from the solar array, regardless of environmental conditions.
Key Features:
Experience the benefits of the Solarthon MPPT Solar Charge And Discharge Controller and optimize your solar energy system for maximum efficiency and energy extraction.

Are you in need of a reliable and efficient inverter for your power needs? Look no further than our pure sine wave inverters! Made by Guangdong Solarthon Technology Co., Ltd., these inverters are designed to provide you with a seamless and high-quality power output.
Key Features:
Choosing the Right Inverter:
If you are unsure about which inverter is suitable for your specific needs, simply share your requirements with our sales team, and they will recommend the most suitable inverter for you.
Power Inverter Necessity:
While not absolutely required, using a power inverter is essential if you want to have access to 220 or 230 volts AC power. Without an inverter, you will solely rely on battery power, which may not be sufficient for most AC appliances.
System Voltage Consideration:
The system voltage, whether it's 12, 24, or 48 volts, determines the input voltage from the battery bank. Higher voltages allow for lower currents, enabling the use of smaller wires between your solar panel array and battery bank. It's important to ensure that all components, including the solar panels, inverter, and battery bank, operate at the same voltage.
Invest in our pure sine wave inverters and enjoy a reliable and efficient power supply for your appliances. For more information, please click here. Thank you!
