AI-Powered supplier vetting

SummaryYueqing JYins Electric Technology Co., Ltd. is identified as a China-based manufacturer of electrical products, including power inverters, meters, switching power supplies, and controllers. The supplier reports four production lines, six R&D engineers, six to ten quality-control staff, and stated annual capacities of 60,000 panel meters and 30,000 power inverters. It has export experience and reports exports representing 71%–90% of total sales. The company describes quality-focused after-sales service and worldwide sales, but provides no management-system certification. Evidence of customization capability, detailed customer references, and financial credibility is insufficient. Trade records show limited transactions associated with Brazil and Ecuador, involving products described as TABURETE and BALANZA, which do not clearly establish relevant electrical-product customer cases.

Supplier typeThe supplier is explicitly classified as a manufacturer and limited company, while associated-company information also identifies a trade-company nature. Its stated product range and factory address support involvement in electrical-product manufacturing, but the mixed classification should be clarified during verification.

CertificationsThe supplier’s management-system certification is explicitly recorded as NIL. This indicates no stated certification evidence was provided for this field.

After-Sales capabilityThe company explicitly states that it prioritizes quality and after-sales services to satisfy customer demands, and claims products are sold internationally with a good reputation. These are supplier assertions, with no quantified service-performance data or independent verification.

R&D capabilityThe supplier states it makes continual efforts in design and technology development and reports six R&D engineers. However, no patents, new-product records, dedicated R&D investment, or independently verified innovation outcomes are provided.

Production capacityThe supplier reports four production lines, six to ten quality-control staff, and stated annual capacities of 60,000 panel meters and 30,000 power inverters. These explicit operating and capacity details support production capability for the listed products.

Product Q&A

Q:Why is your quotation higher than other suppliers?

In the domestic market, high and low inverter brands are mixed. Many low-cost solar power inverters are assembled in small unlicensed workshops using substandard components to reduce costs, posing significant security risks. To protect personal and property safety, please do not covet low prices and choose a reliable inverter.

Q:How many categories does it have according to the output waveform?

Type one: JYM Modified Sine Wave inverter uses PWM pulse width modulation, reducing power loss and ensuring reliability for most electrical equipment, though it has 20% harmonic distortion. Type two: JYP Pure Sine Wave inverter adopts isolated coupling circuit design, offering high efficiency and stability suitable for all loads including inductive devices like refrigerators and electric drills without interference.

Q:Is the output voltage of our inverter stable?

Absolutely. Our inverter is designed with a good regulator circuit, ensuring quite stable output voltage. Many customers find it unstable when using conventional multimeters due to incorrect operation, as ordinary multimeters can only test pure sine waveforms and calculate data.

Q:What is a resistive load appliance?

Generally, appliances like mobile phones, computers, LCD TVs, incandescents, electric fans, video broadcast, small printers, electric mahjong machines, and rice cookers belong to resistive loads. Our modified sine wave solar power inverters can drive them successfully.

Q:What is the inductive load appliance?

It refers to high-power electrical products produced by electromagnetic induction's principle, such as motor types, compressors, relays, fluorescent lamps, electric stoves, refrigerators, air conditioners, energy-saving lamps, and pumps. These products' power is far more than the rated power (about 3-7 times) when starting, so only pure sine wave inverters are available to them.
