Get ready to experience the power of solar energy with our top-of-the-line 20A Solar Charge Controller! Designed by Guangdong Solarthon Technology Co., Ltd., this controller is the perfect addition to your solar power system. With its advanced features and reliable performance, it's time to take your energy independence to the next level.
Our 20A Solar Charge Controller is equipped with a pure sine wave output, ensuring a reliable and efficient power supply. With a wide range of output options, including 110V, 115V, 120V, 220V, 230V, and 240V, this controller is adaptable to your specific needs. And if you have any special requirements, our expert engineers are ready to provide personalized consulting.
But what sets our controller apart is its low frequency design. With enhanced protections and a strong ability to adapt to any environment, it offers unparalleled reliability and voltage regulation. Say goodbye to frequent repairs and hello to a long lifespan!
Not all inverters are created equal, and that's why we offer a pure sine wave output option. Comparable to the public power grid, our pure sine wave inverter goes above and beyond. It boasts a low repair rate, long lifespan, and most importantly, it's environmentally friendly. With no harmonic pollution, your appliances are protected, and you can enjoy a clean and efficient power supply.
On the other hand, modified sine wave inverters can have a negative impact on your appliances. They are not suitable for loading inductive loads like air conditioners and refrigerators. Additionally, certain motor control circuits may not be compatible with the modified wave. That's why our pure sine wave inverter is the superior choice for your power needs.
Worried about compatibility? Don't be! Our 20A Solar Charge Controller can handle a wide range of appliances, making it perfect for household, office, and agricultural use. From refrigerators to air conditioners and water pumps, our inverter has got you covered.
And if you want to add a personal touch, we offer OEM orders. You can have your company logo printed on the inverters, nameplates, and packaging, giving your solar power system a professional and customized look.
Choosing the right inverter has never been easier. Just tell us your requirements, and our knowledgeable sales team will recommend the perfect inverter for you. We're here to make your decision-making process a breeze!
Technical problems? No problem! Our dedicated after-service consultancy is available 24/7 to assist you. We're committed to solving any issues you may encounter and ensuring a seamless experience.
Now, you might be wondering if you really need a power inverter. While it's not absolutely required, having one is essential if you want to enjoy the convenience of normal AC appliances. Without a power inverter, you'll be limited to using battery power alone, which may not be sufficient for most people's needs.
When it comes to choosing the right voltage, we offer 12, 24, and 48 volt inverters. The input voltage from the battery bank is a crucial consideration. Higher voltages allow for smaller wires between your solar panel array and battery bank, making installation easier and more efficient. Remember, all components of your solar power system should use the same voltage.
Lastly, we understand that accidents happen. If any product is faulty, simply send us a picture or video, and we'll study it to identify the issue. We're committed to providing excellent after-sale service, and we'll supply the necessary spare parts of the PCB board free of charge.
Ready to take control of your energy future? Don't miss out on the incredible features and benefits of our 20A Solar Charge Controller. For more information, click here. Thank you!
