Audited Supplier The Solarthon MPPT Solar ChargeAnd 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 can monitor the power generation voltage of the solar panel in real time and track the highest voltage and current values. This ensures that your battery is charged with the maximum power output, resulting in efficient energy extraction from the solar array.
Unlike other controllers, the maximum power point tracking mode of this series of controllers is completely automatic and does not require any user adjustment. It intelligently tracks the maximum power point of the solar panel, adapting to changing environmental conditions to optimize energy extraction.
Whether you have a 20A, 40A, or 60A solar panel system, the Solarthon MPPT Solar ChargeAnd Discharge Controller is a reliable and efficient choice. It is a product of Guangdong Solarthon Technology Co., Ltd., a trusted supplier of solar energy solutions and products.

Are you looking for a reliable and efficient solar power inverter? Look no further! Our pure sine wave output inverters are perfect for your needs. With a true pure sine wave output, they provide the same quality as the public power grid, if not better. These inverters have a low repair rate and a long lifespan, making them a durable and cost-effective choice.
Our inverters come in various output voltages, including 110V, 115V, 120V, 220V, 230V, and 240V, with a self-adapting frequency of 50/60Hz. If you have any special requirements, our engineers are available for consultation.
When it comes to choosing between low frequency and high frequency inverters, the low frequency option offers more protection and adaptability to different environments. It also has voltage regulation capabilities, making it more reliable.
One important distinction to consider is the difference between pure sine wave inverters and modified sine wave inverters. Pure sine wave inverters provide a clean and stable power output, similar to the public power grid. They have a low repair rate, long lifespan, and do not cause harmonic pollution. On the other hand, modified sine wave inverters can have a negative impact on appliances and are not suitable for loading inductive loads such as air conditioners and refrigerators. Certain motor control circuits may also be incompatible with modified sine wave inverters.
Our inverters are versatile and can be used in various settings, including households, offices, and agricultural applications. They are suitable for powering appliances such as refrigerators, air conditioners, water pumps, and more.
If you're looking to customize your inverters, we offer OEM orders, allowing you to print your company logo on the inverters, nameplates, and packaging.
Choosing the right inverter can be made easy with the help of our sales team. Simply tell us your requirements, and we will recommend a suitable inverter for you.
In case you encounter any technical problems, our 24-hour after-service consultancy is available to assist you and ensure that your issues are resolved easily.
While a power inverter is not absolutely required for a solar energy system, it is essential if you want to use normal AC appliances. Without a power inverter, you will only have battery power and will not have access to 220 or 230 volts AC.
The input voltage of the inverter depends on the battery bank. Higher voltages allow for smaller wires between the solar panel array and the battery bank. It is important to ensure that the solar panels, inverter, and battery bank all use the same voltage.
In the rare event that a product is broken, we offer after-sale service. Simply send us a picture or video of the faulty product, and we will study it and provide the necessary spare parts of the PCB board free of charge.
Choose our solar power inverters for reliable, efficient, and environmentally-friendly power conversion. Experience the benefits of renewable energy with our high-quality products.
