AI-Powered supplier vetting

SummaryThe supplier demonstrates broad customization and R&D capabilities, including recent product development and ODM services. It reports OEM service for well-known brands and maintains production equipment covering motor assembly, PCBA assembly, glue injection, coating, and aging processes. Quality-related strengths include stated ISO9001, ISO14001, and OHSAS18001 certifications, documented finished-product inspection instructions, and recorded corrective-action and complaint-handling procedures. However, the supplier has no valid manufacturing-capacity contract with related subcontractors, no overseas warehouse, showroom, agent, or branch, and reports zero countries with overseas service offerings. Financial credibility cannot be assessed from the provided records because the listed entries identify years rather than financial performance or supporting metrics.

Supplier typeThe supplier appears to be a manufacturer with in-house assembly and production processes, supported by OEM, ODM, R&D, inventory, and customization services. Its overseas operating structure is limited: it has no overseas warehouse, showroom, agent, or branch, and reports services in zero countries.

CertificationsThe company states that it has passed ISO9001 quality management, ISO14001 environmental management, and OHSAS18001 occupational health and safety management system certifications. These are explicit certification claims, although no certificate numbers, validity dates, or issuing bodies are provided.

After-Sales capabilityThe supplier has documented procedures and records for supplier-service assessment, corrective and preventive actions, and customer complaint handling, and it offers inventory capability and training as an overseas service. However, it lacks overseas agents, branches, warehouses, and showrooms, limiting evidence of local or physical after-sales coverage.

R&D capabilityThe supplier reports strong scientific research, an innovative R&D team, independent intellectual property rights in industrial automation control technology, new products within the past year, and ODM capability. It does not have an available SDK, but that limitation does not negate the broader evidence of product and technology development.

Production capacityReported production resources include motor assembly, PCBA assembly, glue injection, coating, and aging lines, together with advanced production and testing equipment, inventory capability, and a stated one-month average lead time in both peak and off-season periods. A risk remains because the supplier reports no valid manufacturing-capacity contract with related subcontractors.

Customization capabilityThe supplier explicitly provides customization from samples, customization from designs, full customization, and minor customization. Its stated business model also focuses on personalized solutions, indicating broad customization coverage rather than only limited modification.

Client casesThe supplier states that it provides OEM services for well-known brands and has participated in the ITES offline trade show. These claims provide some customer and market-exposure evidence, but no brand names, project descriptions, order scope, or independently verifiable case details are supplied.

Product Q&A

Q:Does the inverter require manual parameter settings for solar connection?

No, simply connect the solar panels to the inverter without any parameter settings. The solar water pump will start automatically once powered on.

Q:What is the maximum MPPT tracking efficiency?

The advanced MPPT algorithm ensures the solar power tracking efficiency reaches up to 99.8%.

Q:Can the inverter operate continuously without human supervision?

Yes, the entire series supports automatic switching between PV input and grid input, enabling 24-hour unattended operation.

Q:What protection functions are included?

It is equipped with PV overvoltage protection, PV polarity reversal alarm, automatic derating at high temperature, over-current, over-voltage, and under-voltage protection.

Q:What is the speed control range of the inverter?

The speed control range is 1:100 when using SVC (Sensorless Vector Control) mode.
