Are you in need of a reliable and efficient inverter for your solar energy system? Look no further! Our pure sine wave inverters are just what you need. With a true pure sine wave output, they provide the same high-quality power as the public power grid, if not better!
Our inverters come in various output voltages, including 110V, 115V, 120V, 220V, 230V, and 240V, with a self-adapting frequency of 50/60Hz. If you have any special requirements, our engineers are ready to assist you.
Now, let's talk about the difference between low frequency and high frequency inverters. Our low frequency inverters are designed with various protections, making them highly adaptable to any environment. They are more reliable and offer voltage regulation, ensuring the safety and longevity of your appliances.
But what about the difference between pure sine wave and modified sine wave inverters? Our pure sine wave output inverters are top-notch. They have a low repair rate, long lifespan, and zero harmonic pollution. Plus, they are environmentally friendly and provide excellent protection for your appliances. On the other hand, modified sine wave output can negatively impact appliances, especially those with inductive loads like air conditioners and refrigerators. Certain motor control circuits also don't work well with modified wave inverters.
Speaking of appliances, our inverters can handle a wide range of loads. Whether it's for your household, office, or agricultural appliances, our inverters are up to the task. They can power refrigerators, air conditioners, water pumps, and more.
And if you want to add a personal touch to your inverters, we offer OEM orders. You can have your company logo printed on the inverters, nameplates, and packaging.
Choosing the right inverter can be overwhelming, but don't worry! Just let us know your requirements, and our sales team will recommend the perfect inverter for you.
Should you encounter any technical problems, our 24-hour after-service consultancy is here to help. We are dedicated to making your problem-solving experience easy and stress-free.
Now, you might be wondering if you really need a power inverter. Well, technically, no. It's not absolutely required for a solar energy system. However, without an inverter, you won't have access to 220 or 230 volts AC power. This might be acceptable for a small RV or cabin, but most people prefer to use normal AC appliances.
Lastly, let's talk about the different voltages available for our inverters. The 12, 24, and 48 volt options refer to the input voltage from the battery bank. Higher voltages allow for less current, which means you can use smaller wires between your solar panel array and battery bank. Just remember, all components of your system, including the solar panels, inverter, and battery bank, need to use the same voltage.
If you ever encounter a broken product, don't worry! Simply send us a picture or video, and we will study it. We offer free spare parts of PCB boards for after-sale service.
