The Solarthon MPPT Solar Charge and Discharge Controller, manufactured by Guangdong Solarthon Technology Co., Ltd., is a state-of-the-art charging device designed to optimize the power generation of your solar panel system.
MPPT stands for Maximum Power Point Tracking, an advanced charging method that continuously monitors the voltage of your solar panel in real time. By tracking the highest voltage and current values, this controller ensures that your battery is charged with the maximum power output available.
Unlike other controllers, the maximum power point tracking mode of this series is completely automatic, eliminating the need for user adjustment. As the maximum power point of the solar panel changes with environmental conditions, the controller intelligently tracks and adjusts to ensure maximum energy extraction from your solar array.
With the Solarthon MPPT Solar Charge and Discharge Controller, you can optimize the efficiency and performance of your solar panel system, maximizing your energy savings and reducing your carbon footprint.

Product Description:
Q1: Are your inverters pure sine wave output?
A: Yes, all our inverters provide true pure sine wave output.
Q2: What kind of output can your inverters provide?
A: 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.
Q3: What's the difference between low frequency and high frequency inverters?
A: Low frequency inverters offer various protections, strong adaptability to the environment, and reliable voltage regulation. They are more durable and reliable compared to high frequency inverters.
Q4: What's the difference between pure sine wave and modified sine wave inverters?
A: Pure sine wave output inverters provide power similar to the public power grid, offering low repaired rates, long lifespan, no harmonic pollution, and appliance protection. On the other hand, modified sine wave output can negatively impact appliances and cannot load inductive loads such as air conditioners and refrigerators. Certain motor control circuits may not function well with modified sine wave inverters.
Q5: What appliances can your inverters load?
A: Our inverters can be used with household, office, and agricultural appliances, as well as other inductive loads such as refrigerators, air conditioners, water pumps, etc.
Q6: Can you print our company logo on inverters, nameplates, and packaging?
A: Yes, we accept OEM orders and can customize the products with your company logo.
Q7: How do I choose the right inverter?
A: Please inform us of your requirements, and our sales team will recommend a suitable inverter for you.
Q8: How do I solve technical problems?
A: We provide 24-hour after-service consultancy to help you solve technical problems easily.
Q9: Do I need a power inverter?
A: While a power inverter is not absolutely required for a solar energy system, it is necessary if you want to use normal AC appliances. Without a power inverter, you will only have battery power and not have access to 220 or 230 volts AC.
Q10: What's the difference between 12, 24, and 48 volt inverters?
A: The voltage refers to the input voltage from the battery bank. Higher voltages allow for less current, enabling the use of 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.
Q11: What should I do if the product is broken?
A: If any product is faulty, please send us pictures or videos for our assessment. We will provide free spare parts of PCB boards for after-sale service.
