Can you print our company logo on inverters, nameplates, and packaging?

Yes, we accept OEM orders and can print your company logo on the inverters, nameplates, and packaging.

How do I solve technical problems?

We offer 24-hour after-service consultancy to help you easily solve any technical problems you may encounter.

Do I need a power inverter?

While not absolutely required, a power inverter is necessary if you want to have 220 or 230 volts AC and use normal AC appliances. Without a power inverter, you will only have battery power, which may be acceptable for small RVs or cabins.

What should I do if the product is broken?

If any product is faulty, please send us pictures or videos, and we will provide free spare parts for the PCB board as part of our after-sale service.

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:Are your inverters pure sine wave output?

Yes, all our inverters have a true pure sine wave output.

Q:What kind of output can you provide?

We normally produce inverters with 110V, 115V, 120V, 220V, 230V, and 240V, with a self-adapting frequency of 50/60Hz. If you have special requirements, please consult our engineers.

Q:What's the difference between low frequency and high frequency inverters?

Low frequency inverters offer various protections and have a strong ability to adapt to different environments. They are more reliable and have voltage regulation capabilities.

Q:What's the difference between pure sine wave inverters and modified sine wave inverters?

Pure sine wave output inverters provide power that is just as good as the public power grid, if not better. They have a low repair rate, long lifespan, no harmonic pollution, and are environmentally friendly. They also protect appliances. On the other hand, modified sine wave output inverters can have a negative impact on appliances and cannot load inductive loads such as air conditioners and refrigerators. Certain motor control circuits may not work well with modified sine wave output.

Q:What appliances can your inverters load?

Our inverters can be used with household, office, and agricultural appliances, as well as other inductive loads such as refrigerators, air conditioners, and water pumps.
