Frequently Asked Questions about Solarthon Inverters
Q: Are your inverters pure sine wave output?
A: Yes, all our inverters provide true pure sine wave output.
Q: What kind of output can your inverters provide?
A: Normally, we produce inverters with 110V, 115V, 120V, 220V, 230V, and 240V output options. These inverters have a self-adapting frequency of 50/60Hz. If you have special requirements, please consult our engineers.
Q: What's the difference between low frequency and high frequency inverters?
A: Low frequency inverters offer various protections, strong environmental adaptability, and reliable voltage regulation. On the other hand, high frequency inverters lack these features.
Q: 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, with low repair rates, long lifespan, no harmonic pollution, and environmental-friendly operation. Modified sine wave output inverters have a negative impact on appliances, especially inductive loads like air conditioners and refrigerators. Certain motor control circuits may not work well with modified sine wave inverters.
Q: What appliances can your inverters load?
A: Our inverters can be used with household, office, and agricultural appliances, including inductive loads such as refrigerators and air conditioners.
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 you.
Q: How do I solve technical problems with the inverters?
A: We offer 24-hour after-service consultancy to help you easily solve any technical problems you may encounter.
Q: 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 an inverter, you will only be able to use battery power.
Q: 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 lower currents, which means you can use smaller wires between your solar panel array and battery bank. It's important to ensure that all components of your system, including the solar panels, inverter, and battery bank, use 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 it and provide the necessary spare parts for free as part of our after-sale service.
