Is a power inverter necessary for a solar energy system?

While not absolutely required, having one allows you to have 220 or 230 volts AC power, enabling you to use normal AC appliances.

What voltage options do your inverters support?

Our self-adaptive inverters can meet specific requirements for 110V, 115V, 120V, 220V, 230V, or 240V.

What is the lead time for orders?

The average lead time is within 15 workdays for both peak and off-peak seasons.

AI-Powered supplier vetting

SummaryThe supplier is identified as a manufacturer with photovoltaic, new-energy, lighting, electronic-component, and related product activities. It reports six production lines, stated annual output for portable power stations, solar batteries, solar controllers, inverters, and solar panels, and valid manufacturing-capacity contracts with associated subcontractors. Customization, ODM, and OEM services are available, and the supplier states that it developed new products during the past year. However, no certification information, after-sales service capability, overseas agents or branches, overseas warehouses, or overseas showrooms is provided; it also reports no inventory capability and no available SDK. Financial information is present only as year references, without sufficient evidence to assess credibility. Customer cases are not identified, although OEM service for recognized brands is stated.

Supplier typeThe supplier is explicitly classified as a manufacturer. Its stated business scope covers photovoltaic equipment and components, new-energy power equipment, lighting products, electronic components, semiconductor lighting devices, and hardware products, indicating a manufacturing-oriented supplier with a broad related-product scope.

R&D capabilityThe supplier states that it had new products during the past year and provides ODM services. Its business scope also includes new-material technology research and development and technical development services. Conversely, it reports no available SDK, which limits evidence for software-development integration but does not negate the stated product and technical R&D capabilities.

Production capacityThe supplier reports six production lines, defined assembly and testing facilities, stated annual product outputs, and valid contracts with each associated subcontractor. It also reports lead times within 15 workdays in both peak and off-season, although the slices do not provide independent verification of capacity or delivery performance.

Customization capabilityCustomization is explicitly offered from samples and designs, including full, minor, and flexible customization. The same capability is repeated in the production-related information, providing direct evidence that the supplier supports multiple customization levels.

Product Q&A

Q:What is the warranty period?

We provide a comprehensive 3-year warranty for all our mechanical equipment.

Q:What is the difference between your inverters and high frequency ones?

Our low frequency inverters offer superior protection, adaptability, and reliability with voltage regulation designed to withstand various environmental conditions.

Q:Can your inverters handle inductive loads like air conditioners?

Yes, our pure sine wave output inverters are excellent for inductive loads like air conditioners and refrigerators, unlike modified sine wave inverters which can cause negative impacts.

Q:Do you offer customization services?

Yes, we offer OEM orders where you can have your company logo printed on the inverters, nameplates, and packaging, along with full customization options.

Q:What happens if a product is faulty?

Simply send us a picture or video of the issue, and we will study it and supply the necessary spare parts of the PCB board free of charge.
