Audited Supplier The Solarthon MPPT Solar Charge and Discharge Controller is designed to optimize the charging process of solar panels. Equipped with maximum power point tracking (MPPT) technology, this controller can monitor the voltage and current of the solar panel in real-time. It automatically tracks the highest voltage and current values, allowing for efficient charging of the battery with maximum power output.
With its automatic tracking feature, this controller eliminates the need for user adjustment. It intelligently adjusts to the changing environmental conditions, ensuring that the solar panel operates at its maximum power point. This results in maximum energy extraction from the solar array, allowing for optimal power generation.
The Solarthon MPPT Solar Charge and Discharge Controller is available in three different models: 20A, 40A, and 60A. Whether you have a small-scale or large-scale solar system, there is a controller suitable for your needs.
Trust in the quality and reliability of Solarthon Technology Co., Ltd., a leading company in the solar energy industry.

Question: Yes, All are true pure sine wave.
Question: Normally we produce inverters with 110V, 115V, 120V, 220V, 230V, and 240V, 50/60Hz self-adaption. If you have special requirements, please tell us for engineer consulting.
Question: Low frequency inverters have various protections, strong ability to adapt to the environment, and are more reliable with voltage regulation.
Question: Pure sine wave output inverters are just as good as the public power grid, even better. They have a low repair rate, long lifespan, no harmonic pollution, and are environmentally friendly. Modified sine wave output has a negative impact on appliances and can't load inductive load, such as air conditioners and refrigerators. Certain motor control circuits don't like the modified wave.
Question: Our inverters can be used in households, offices, agricultural appliances, and other inductive loads such as refrigerators, air conditioners, water pumps, etc.
Question: Yes, we accept OEM orders.
Question: Tell us your demand, then our sales will recommend a suitable inverter to you.
Question: We offer 24-hour after-service consultancy to help you solve your problems easily.
Question: Actually, no. This is the only component of a solar energy system that is not absolutely required. However, if you don't use one, you will not have 220 or 230 volts AC and will have to use battery power alone. This might be acceptable in a small RV or cabin, but most people want to use normal AC appliances.
Question: This refers to the input voltage from the battery bank. The main consideration is that at higher voltages, the current is less so that you can use smaller wires between your solar panel array and your battery bank. Of course, when you decide on a system voltage, the solar panels, inverter, and battery bank all need to use the same voltage.
Question: If any product is faulty, you can send the picture or video to us. We will study it and supply the spare parts of PCB board free for after-sale service.
