Frequently Asked Questions
Q: Are these power inverters and chargers reliable?
A: Yes, our products are manufactured using advanced production equipment and a strict ISO 9001 certified quality control system. Every unit undergoes rigorous testing from raw materials to the finished product, carrying CE, RoHS, and TÜV certifications.
Q: What is the efficiency rating of the power inverters?
A: Our high-quality pure sine wave inverters utilize high-efficiency transformer isolation, reaching efficiency levels of over 90%, with some models achieving approximately 95% efficiency.
Q: What types of output waveforms are available?
A: We offer both pure sine wave and modified sine wave inverters. Pure sine wave inverters provide a waveform identical to grid power, making them ideal for sensitive electronics like refrigerators and medical equipment.
Q: Why would an inverter have no output?
A: This may be due to loose input connections, a blown internal fuse from an overload, or an internal protection circuit being triggered. Always check the input power source and fuse status first.
Q: Can products be customized for specific requirements?
A: Yes, we offer comprehensive customization services. We can design and produce units based on your specific needs for input/output voltage, power ratings, waveform types, and special physical dimensions.
Q: What should I do if the output voltage is unstable?
A: Check the input power supply for fluctuations. If the battery is low, recharge it. Also, ensure the total connected load does not exceed the rated output power of the inverter.
