FAQ:
Is it a pure sine wave or a modified sine wave? What's the difference?

This is a modified sine wave inverter, suitable for most conventional home appliances and electronic devices; pure sine wave is suitable for precision devices with extremely high power requirements. This modified sine wave is more cost-effective at 2000W, meeting the needs of most scenarios.

Can I customize the logo?

Yes, OEM/ODM service is available.

Can I customize the color and logo?

Yes, OEM/ODM customization is supported.

Is customization available?

OEM/ODM support for logo, color, and packaging design.

What capacity battery is needed to meet long-term use?

It needs to be calculated according to the total power of the device, the formula is "Battery Capacity (Ah) = Total Device Power (W) × Usage Time (h) ÷ Input Voltage (12V)". For example, to drive a 1000W device for 5 hours, the required battery capacity = 1000×5÷12≈417Ah, it is recommended to use 2 200Ah batteries in parallel (total capacity 400Ah, actual usage about 4.8 hours).
