AI-Powered supplier vetting

SummaryAswich Electrical Co., Ltd is an established electrical-component manufacturer founded in 1988, with more than 30 years of experience, a 30,000-square-meter production base, automated production lines, and stated annual DC isolator output of 1,000,000 pieces. It demonstrates broad customization capability, recent new-product activity, quality assurance, ISO9001:2015 and ISO14001 accreditation, and UL-related certification capability. Customer complaint handling is documented, but corrective and preventive actions for service capability lack written procedures or records. The supplier has valid manufacturing contracts with associated subcontractors but reports no inventory, overseas warehouse, overseas showroom, overseas agents, or branches. Financial information is present for multiple years, but the provided slices do not establish financial strength. No specific customer cases or named customers are supplied.

Supplier typeThe supplier is identified as an electrical and electrical-component manufacturer and seller, with experience manufacturing switches and circuit breakers since 1988. Its owned production base, laboratory, automated lines, and stated DC isolator output support classification as a manufacturer rather than only a trader.

CertificationsThe company is stated to hold ISO9001:2015 and ISO14001 accreditation, and its sustainable-development and product-certification capability lists UL and other certifications. These are explicit certification-related strengths, although the specific UL-certified products are not identified.

After-Sales capabilityThe supplier has a clear procedure and followed records for customer complaints, but it has no written procedures or records for corrective and preventive actions related to service capability. It also reports no inventory, overseas warehouse, overseas showroom, overseas agents, or branches, limiting evidence of local or rapid overseas support.

R&D capabilityThe supplier reports new products during the past year, high R&D investment, 50 total years of R&D engineer experience, and a national science and technology progress award. It does not provide an SDK and does not offer ODM services, but these limitations do not negate the explicit evidence of product R&D capability.

Production capacityProduction evidence includes a 30,000-square-meter plant, multiple automated production lines, an owned laboratory, valid contracts with each associated subcontractor, and stated DC isolator output of 1,000,000 pieces. Finished products are checked by packing staff, while no inventory capability is reported; overall manufacturing capacity is supported, but the inspection method appears limited in the provided information.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, and flexible customization. This is reinforced by the listed design-service capability for customization from samples, demonstrating broad stated customization coverage.

Product Q&A

Q:What is the maximum output wire size supported?

The unit currently fits up to 6 AWG wire. Although it can run max 58A, we recommend using 4-6 AWG wire. The next version will support 4 AWG wires.

Q:Can this combiner box handle a 1600W system (4s4p 100W 12V panels)?

Yes, if configured correctly. Connect 4 panels in 1 string to get 48V. Use 1 string in this box. With 4 strings (16 panels total), the max current per string is 15A, which fits the cords and fuses.

Q:Where can I buy replacement 15A fuses?

We provide 4 extra 15A fuses in the original package. If you need more, please view the provided link for purchase.

Q:Will this work with 12x400W panels connected as 3 in series (4 total), pushing 60A?

No. The fuse is rated at 15A. A 60A current will exceed the fuse rating and is not supported by this unit.

Q:What are the available input and output string configurations?

The combiner box supports various configurations including 1in 1out, 2in 2out, 2in 1out, 3in 1out, and 3in 3out.
