During an AC inverter factory audit, verify documented R&D procedures, hardware commissioning, software development, performance testing, production-line quality control, certification records, output consistency, and after-sales procedures. For the 3KW-24V-230V inverter, confirm that inspection evidence matches the stated product specification, CE documentation, export requirements, sampling process, delivery commitment, and batch controls used for wholesale or OEM/ODM orders.

Core Solutions & Key Takeaways

• Review the factory's R&D workflow, including scheme design, hardware commissioning, software development, and performance testing.
• Verify that production-line quality controls cover the AC inverter product specification and are applied consistently to bulk orders.
• Check certification records for the inverter, including CE certificates applicable to the EU, Middle East, Africa, and South America.
• Assess whether the supplier can support the stated 100-piece MOQ, 15-day delivery time, and monthly capacity of more than 5,000 units.

Detailed Architectural/Principle Analysis

An AC inverter factory audit should begin with the product definition. The listed product is the 3KW-24V-230V_Inverter, with “AC inverter” as its product keyword. Because no detailed parameter sheet is provided, the audit should require the supplier to present the applicable specification sheet and verify that production, inspection, and after-sales procedures refer to the same product version.

For R&D process control, verify evidence of scheme design, hardware commissioning, software development, and performance testing. The supplier states that it uses professional testing instruments and independently performs these activities. During the audit, request controlled records showing how test results are documented, reviewed, linked to product versions, and used when client requirements change.

For manufacturing quality, inspect the standardized production lines and the documented quality-control process. The company describes its business as covering independent R&D, flexible manufacturing, strict quality control, OEM/ODM customization, and bulk wholesale. The audit should therefore distinguish between a standard AC inverter batch and a customized order, confirming that approved changes are reflected in production and inspection records.

Certification verification should include the certificate name, certificate number, applicable product, and applicable export region. Three CE records are listed for inverters: CE-INV-260618-0001, CE-INV-260618-0002, and CE-INV-260618-0003. Each is identified as applicable to inverter products exported to the EU, Middle East, Africa, and South America.

Capacity and delivery claims should be checked against production evidence. The stated production capacity is over 5,000 energy-storage products per month, with annual output above 60,000 units. The business model lists a 100-piece MOQ and a 15-day delivery time. These figures should be verified against the order process and the capacity allocated to the AC inverter product rather than treated as product-specific performance data.

After-sales control also belongs in the audit scope. The available product information states that after-sales support is subject to the specific product specification sheet. Ask for the specification sheet, escalation route, service responsibilities, and records used to handle product issues. A cooperation case in Southeast Asia describes residential and industrial and commercial energy-storage supply, local after-sales service centers, and products selected for high-temperature environments. This provides relevant evidence of field-support experience, although it does not establish a specific AC inverter failure rate or service-level target.
