Introducing our high-quality inverters from Guangdong Solarthon Technology Co., Ltd. Our inverters are designed to meet the reading habits of English-speaking natives, providing a reliable and efficient power solution for various applications.
Q: Are your inverters pure sine wave output?
A: Yes, all our inverters provide true pure sine wave output, ensuring a stable and clean power supply.
Q: What kind of output can you provide?
A: Our inverters are available in various output voltages, including 110V, 115V, 120V, 220V, 230V, and 240V. They also feature a self-adaption capability for 50/60Hz frequency. If you have specific requirements, our engineers are available for consultation.
Q: What's the difference between low frequency and high frequency inverters?
A: Our low frequency inverters offer enhanced protection, adaptability to different environments, and reliable voltage regulation. They are more durable and reliable compared to high frequency inverters.
Q: What's the difference between pure sine wave and modified sine wave inverters?
A: Our pure sine wave output inverters provide power quality equivalent to the public power grid, if not better. They have a low repair rate, long lifespan, and do not cause harmonic pollution. On the other hand, modified sine wave inverters can negatively impact appliances, especially inductive loads like air conditioners and refrigerators. Certain motor control circuits may not be compatible with modified sine wave output.
Q: What appliances can your inverters load?
A: Our inverters are suitable for household, office, and agricultural appliances. They can handle inductive loads such as refrigerators, air conditioners, water pumps, and more.
Q: 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.
Q: How do I choose the right inverter?
A: Simply tell us your requirements, and our sales team will recommend a suitable inverter for your needs.
Q: How can I solve technical problems?
A: We offer 24-hour after-service consultancy to assist you in solving any technical issues you may encounter.
Q: Do I need a power inverter?
A: While not absolutely required, a power inverter is essential if you want to have 220 or 230 volts AC power and use normal AC appliances. Without a power inverter, you will solely rely on battery power, which may be suitable for small RVs or cabins.
Q: What's the difference between 12, 24, and 48 volt inverters?
A: The input voltage refers to the battery bank voltage. Higher voltages allow for lower currents, enabling the use of smaller wires between your solar panel array and battery bank. It's important to ensure that the solar panels, inverter, and battery bank all operate at the same voltage.
Q: What should I do if the product is broken?
A: If any product is faulty, simply send us a picture or video, and we will study the issue. We provide free spare parts of PCB boards for after-sale service.
