Audited Supplier The Solarthon MPPT Solar Charge And Discharge Controller, manufactured by Guangdong Solarthon Technology Co., Ltd., is designed to maximize the efficiency of your solar power system.
MPPT, which stands for maximum power point tracking, is an advanced charging method that continuously monitors the power generation voltage of your solar panel. It tracks the highest voltage and current values in real time, allowing the system to charge the battery with maximum power output.
Unlike other controllers, the maximum power point tracking mode of this series of controllers is completely automatic, eliminating the need for user adjustment. As the maximum power point of the solar panel varies with environmental conditions, this controller intelligently tracks and adjusts to ensure maximum energy extraction from the solar array.
With the Solarthon MPPT Solar Charge And Discharge Controller, you can enjoy the following features and benefits:
Upgrade your solar power system with the Solarthon MPPT Solar Charge And Discharge Controller and experience enhanced efficiency and energy extraction.

Are you looking for a reliable and efficient power inverter? Look no further! Introducing the pure sine wave inverters from Guangdong Solarthon Technology Co., Ltd. Our inverters are designed to meet the reading habits of English-speaking natives and are perfect for both residential and commercial use.
Yes, all our inverters provide a true pure sine wave output.
Our inverters are available in various output voltages, including 110V, 115V, 120V, 220V, 230V, and 240V. They also feature a 50/60Hz self-adaption capability. If you have any special requirements, our engineers are available for consultation.
Low frequency inverters offer superior protection, adaptability, and reliability. They also feature voltage regulation capabilities. On the other hand, high frequency inverters lack these advantages.
Pure sine wave inverters provide power output similar to the public power grid, or even better. They have a low repair rate, long lifespan, and do not produce harmonic pollution. In contrast, modified sine wave inverters can negatively impact appliances, especially those with inductive loads. They are not suitable for use with air conditioners, refrigerators, and certain motor control circuits.
Our inverters can be used with a wide range of appliances, including those found in households, offices, and agricultural settings. They are particularly suitable for use with inductive loads such as refrigerators and air conditioners.
Yes, we accept OEM orders and can print your company logo on the inverters, nameplates, and packaging.
Simply tell us your requirements, and our sales team will recommend a suitable inverter for your needs.
We offer 24-hour after-service consultancy to assist you in solving any technical issues you may encounter.
While not absolutely required, a power inverter is essential if you want to have access to 220 or 230 volts AC power. Without an inverter, you would have to rely solely on battery power, which may not be sufficient for most AC appliances.
The voltage refers to the input voltage from the battery bank. Higher voltages allow for lower current, enabling the use of 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, simply send us a picture or video, and we will study the issue. We offer free spare parts of PCB board for after-sale service.
