AI-Powered supplier vetting

SummaryThe supplier demonstrates OEM/ODM and broad customization capabilities, supported by stated experience, R&D personnel, quality-control staff, ISO 9001 certification, and multiple production lines. Export orientation is substantial, with 71%–90% of sales from exports and export activity beginning in 2020. However, no overseas warehouses, showrooms, agents, branches, or offline trade-show participation are reported, and no main export-market presence is recorded. Service procedures exist, but corrective-action and complaint-handling records are not documented. Financial credibility cannot be reliably assessed because the provided financial figures are non-informative and monetary data is excluded.

Supplier typeThe supplier presents itself as a manufacturer with OEM experience, three reported production lines, and both agency-assisted and self-operated export channels. Its product range includes rack-mount inverters, switching power supplies, static transfer switches, and DC converters.

CertificationsThe supplier reports ISO 9001 certification and CE product certification capability. These certifications provide explicit evidence of quality-system and product-compliance credentials, although no further certification scope or validity details are supplied.

R&D capabilityThe supplier reports new products during the past year, offers ODM services, and has 6–10 R&D engineers. However, it reports no available SDK, so software-development integration capability is not demonstrated.

Production capacityThe supplier reports two production lines in one manufacturing record and three in another, plus ongoing quantity reconciliation for each batch or batch production. It also describes controls covering materials, SMT, assembly, aging tests, inspection, and packing, indicating established manufacturing and quality-control processes.

Customization capabilityThe supplier explicitly provides customization from samples, designs, full customization, minor customization, and flexible customization. Its stated OEM experience and ODM availability further support broad product-development flexibility.

Product Q&A

Q:Do you have charging solution?

Yes, suitable for battery charging usage. Our rectifier system is widely used for N+1 power supply and battery charging system management.

Q:Does the product support the SNMP function?

Yes, 90% of BWITT products support SNMP. All products have built-in RS485 communication as standard.

Q:What is RS485?

RS485 is a communication interface that supports real-time data communication. It allows monitoring software to monitor and control the inverter power supply in real-time.

Q:How about the inverter load?

It has super overload capacity, can withstand full load startup, and with a bypass switch, can switch to bypass power supply when overloaded.

Q:Can I choose the mains mode for my inverter power supply?

Yes, BWITT inverters support AC main power supply and DC main power supply. The mode can be changed via the LCD panel or communication background software.
