AI-Powered supplier vetting
SummaryThe supplier is a renewable-energy power-products enterprise producing wind and solar controllers, inverters, generators, converters, and related equipment. It holds an ISO9001:2015 certificate, reports dedicated quality-control resources and documented inspection procedures, and has documented corrective-action and complaint-handling processes. Its technical profile is strong: it provides 3D design, SDK, ODM, OEM, and multiple customization options, and reports new products within the past year. Production evidence includes three lines and stated annual capacities for inverters and charge controllers, but manufacturing capacity lacks a valid contract with affiliated subcontractors. Overseas support is limited by the absence of overseas branches, agents, warehouses, and showrooms. Financial credibility cannot be assessed because the slices only identify reporting years, not financial results or ratios. No specific customer cases are provided.
Supplier typeThe supplier is explicitly described as a high-tech enterprise focused on researching, producing, selling, and servicing renewable-energy power products. It is also identified as a professional technical supplier offering ODM and OEM services, indicating both manufacturing and technical-solution capabilities.
CertificationsThe supplier reports holding an ISO9001:2015 certificate. This is explicit evidence of a recognized quality-management certification, although the slices do not provide the certificate scope or validity date.
After-Sales capabilityThe supplier has documented corrective/preventive-action and complaint-handling procedures with records, written service-capability assessment procedures, finished-product inspection instructions, and stated installation, training, repair, maintenance, and debugging services. However, it has no overseas agents or branches, no overseas warehouse or showroom, and lists zero countries for overseas services, so international service reach is limited.
R&D capabilityThe supplier reports 16 years of total R&D-engineer experience, professional technical-supplier capability, available SDK support, and new products developed within the past year. It also offers 3D software design and ODM services, providing explicit evidence of product-development capability.
Production capacityThe supplier operates three production lines, reports annual capacity of 10,000 inverter sets and 10,000 charge-controller sets, and has documented finished-product inspection instructions. However, it reports no valid manufacturing-capacity contract with its affiliated subcontractors, which creates a documented capacity-management weakness despite the stated in-house production indicators.
Customization capabilityThe supplier explicitly supports customization from samples, designs, full customization, minor customization, and flexible customization. Its 3D design, SDK, ODM, and OEM capabilities further support the conclusion that it can adapt products to customer requirements.
Product Q&A
Q:What is the output waveform?
A:
The output waveform is a pure sine wave with low harmonic distortion.
Q:Can the output voltage be adjusted?
A:
Yes, the low-grade voltage adjusts from 0 to 150V and high-grade from 0 to 300V continuously.
Q:What is the dynamic response time?
A:
The dynamic reaction rate is less than 2ms, ensuring fast and safe protection steps.
Q:Does the device support unbalanced loads?
A:
Yes, the three-phase power supply can adapt to 100% unbalanced load conditions.
Q:What is the overload capacity?
A:
It supports 110% overload for 10 minutes and 200% overload for 10 seconds.
