Audited Supplier The Solarthon MPPT Solar Charge and Discharge Controller, manufactured by Guangdong Solarthon Technology Co., Ltd., is an advanced charging solution that maximizes the power output of your solar panel system.
MPPT stands for Maximum Power Point Tracking. This innovative technology allows the controller to continuously monitor the voltage of your solar panels and track the highest voltage and current values in real time. By doing so, it ensures that your battery is charged with the maximum power output.
With the Solarthon MPPT Solar Charge and Discharge Controller, you don't need to worry about manually adjusting settings. Its maximum power point tracking mode is completely automatic. It adapts to changing environmental conditions, automatically tracking the maximum power point of your solar panel system. This guarantees that you extract the highest possible amount of energy from your solar array.
The Solarthon MPPT Solar Charge and Discharge Controller is available in three power capacity options: 20A, 40A, and 60A. You can select the one that best suits your system's requirements.

Yes, all our inverters provide true pure sine wave output.
Normally, we produce inverters with 110V, 115V, 120V, 220V, 230V, and 240V, 50/60Hz self-adaption. If you have special requirements, please consult our engineers.
Low frequency inverters have various protections, strong adaptability to the environment, and are more reliable with voltage regulation.
Pure sine wave output inverters provide power similar to the public power grid, with low repair rate, long lifespan, no harmonic pollution, and environmental friendliness. On the other hand, modified sine wave output inverters can have a negative impact on appliances and cannot load inductive loads such as air conditioners and refrigerators. They are not preferred by certain motor control circuits.
Our inverters can be used with household, office, and agricultural appliances, including inductive loads such as refrigerators, air conditioners, and water pumps.
Yes, we accept OEM orders and can incorporate your company logo on inverters, nameplates, and packaging.
Simply tell us your requirements, and our sales team will recommend a suitable inverter for you.
We offer 24-hour after-service consultancy to help you easily solve any technical problems you may encounter.
While not absolutely required, a power inverter 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.
The difference refers to the input voltage from the battery bank. Higher voltages allow for less current, which means you can use smaller wires between your solar panel array and battery bank. It's important to ensure that the solar panels, inverter, and battery bank all use the same voltage.
If any product is faulty, please send us pictures or videos, and we will study the issue and provide the necessary spare parts of PCB board for after-sale service.
