Frequently Asked Questions

How does a power inverter work?

A power inverter converts DC power from a battery into conventional AC power. You simply connect the inverter to a battery source and plug your appliance into the AC outlet.

What types of batteries can I use?

The inverter is suitable for all types of 12V/24V/48V batteries (depending on model) including lead-acid, lithium, and AGM.

What is the difference between resistive and inductive loads?

Resistive loads include phones, laptops, and lights. Inductive loads use electromagnetic induction (motors, compressors, AC units) and require 3-7 times their rated power at startup, meaning only pure sine wave inverters are suitable.

Do you offer OEM/ODM services?

Yes, we offer customization services to meet your unique branding and technical requirements.

What is the warranty period?

We provide a standard 24-month warranty and offer global technical assistance and spare parts support.

Where should I install the inverter?

Install it in a well-ventilated, cool, dry, and waterproof location. Ensure there is enough space for the cooling fans to operate effectively.
