Frequently Asked Questions
What’s the main difference between your OEM and ODM services?
OEM uses your brand on our standard products; ODM creates entirely new products based on your concept or specification.
How long does it take to become an authorized distributor?
The process typically takes 2-4 weeks, depending on the discussion and agreement finalization.
Can this inverter support both 12V and 24V inputs
Yes, it can work with different voltage systems via selectable input terminals.
What is the difference between modified sine wave and pure sine wave?
Modified sine wave is suitable for most ordinary home appliances and electronic devices; pure sine wave is suitable for devices with extremely high power requirements (such as precision instruments). This modified sine wave is more cost-effective and meets the needs of most daily scenarios.
