Audited Supplier The Solarthon MPPT Solar Charge and Discharge Controller, developed by Guangdong Solarthon Technology Co., Ltd., is an advanced charging solution that maximizes the power output of solar panels.
The Solarthon MPPT Solar Charge and Discharge Controller utilizes MPPT technology to continuously monitor the power generation voltage of solar panels. By tracking the highest voltage and current values, it ensures that the battery is charged with the maximum power output available. The controller's automatic tracking feature adjusts to the varying maximum power point of the solar panel based on environmental conditions, guaranteeing optimal energy extraction from the solar array.

Q: Are your inverters pure sine wave output?
A: Yes, all our inverters have a true pure sine wave output.
Q: What kind of output can you provide?
A: Normally, we produce inverters with self-adapting 110V, 115V, 120V, 220V, 230V, and 240V outputs at 50/60Hz. If you have special requirements, please consult our engineers.
Q: What's the difference between a low frequency and high frequency inverter?
A: A low frequency inverter offers various protections, strong adaptability to different environments, and reliable voltage regulation. On the other hand, a high frequency inverter may not provide the same level of reliability or adaptability.
Q: What's the difference between a pure sine wave inverter and a modified sine wave inverter?
A: A pure sine wave output inverter provides power that is as good as the public power grid, if not better. It has a low repair rate, long lifespan, no harmonic pollution, and is environmentally-friendly. On the other hand, a modified sine wave output can negatively impact appliances and cannot handle inductive loads such as air conditioners and refrigerators. Certain motor control circuits may also not be compatible with a modified sine wave.
Q: What appliances can your inverters handle?
A: Our inverters can be used with household, office, agricultural appliances, and other inductive loads such as refrigerators, air conditioners, and water pumps.
Q: Can you print our company logo on the inverters, nameplates, and packaging?
A: Yes, we accept OEM orders and can customize the inverters, nameplates, and packaging with your company logo.
Q: How do I choose the right inverter?
A: Simply tell us your requirements, and our sales team will recommend a suitable inverter for you.
Q: How do I solve technical problems?
A: We offer 24-hour after-service consultancy to help you easily solve any technical problems you may encounter.
Q: Do I need a power inverter?
A: Technically, no. A power inverter is not absolutely required in a solar energy system. However, without one, you will not have access to 220 or 230 volts AC and will have to rely solely on battery power. While this may be acceptable for small RVs or cabins, most people prefer to use normal AC appliances.
Q: What's the difference between 12, 24, and 48 volt inverters?
A: The voltage refers to the input voltage from the battery bank. The main consideration is that higher voltages result in lower currents, allowing for the use of smaller wires between the solar panel array and the battery bank. It's important to note that when deciding on a system voltage, the solar panels, inverter, and battery bank must all use the same voltage.
Q: What should I do if the product is broken?
A: If any product is faulty, please send us a picture or video, and we will study it and provide the necessary spare parts for the PCB board free of charge for after-sale service.
