When auditing an MPPT controller factory, request production records covering design control, hardware commissioning, software development, performance testing, incoming and process inspection, safety testing, ageing, and final release. For the 36 48V Solar Charge Controller, also verify the applicable inspection scope, test results, batch traceability, corrective actions, and evidence that the factory can meet the stated 100-piece MOQ and 15-day delivery time.

Core Solutions & Key Takeaways

• Request R&D records for scheme design, hardware commissioning, software development, and performance testing.
• Review quality records for appearance checks, voltage and internal-resistance detection, charge-discharge capacity testing, BMS-protection verification, hi-pot insulation testing, high-low-temperature experiments, vibration and drop testing, and ageing burn-in screening.
• Verify production records against the 36 48V Solar Charge Controller product specification, including inspection requirements, after-sales conditions, export markets, MOQ, and delivery time.
• Check whether the factory can support photovoltaic applications such as off-grid PV power stations and grid-tied energy-storage systems.

Detailed Architectural/Principle Analysis

An audit should begin with product identity and process scope. The supplied product is a 36 48V Solar Charge Controller associated with the keyword MPPT solar charge controller. Request the approved product information, production batch records, and inspection records that identify the product consistently throughout manufacturing and release.

For technical process verification, request records showing how the manufacturer independently conducts scheme design, hardware commissioning, software development, and performance testing. These records should be linked to the audited product or production batch where applicable, allowing the auditor to compare the documented process with the delivered product specification.

The available quality-inspection scope includes appearance checks, voltage and internal-resistance detection, charge-discharge capacity testing, BMS-protection verification, hi-pot insulation testing, high-low-temperature experiments, vibration and drop tests, and ageing burn-in screening. Because this inspection description refers to energy-storage batteries, the auditor should confirm which checks apply directly to the MPPT controller and which belong to associated energy-storage products.

Request signed or system-generated results for each applicable test, together with nonconformance records and corrective-action evidence. The available data does not specify numerical acceptance limits, so the audit should compare results with the applicable product specification sheet rather than assume unstated thresholds.

The company reports a production capacity of over 5,000 energy-storage products per month and more than 60,000 units annually. Its R&D team covers energy storage, inverter, and photovoltaic control technologies, with professional testing instruments used for design, commissioning, software development, and performance testing.

Three CE certifications are listed for inverters, with certificate numbers CE-INV-260618-0001, CE-INV-260618-0002, and CE-INV-260618-0003. These certificates apply to exports to the EU, Middle East, Africa, and South America. They are relevant company credentials, but they should not be treated as certification evidence for the MPPT solar charge controller unless the applicable product documentation confirms that scope.

A documented cooperation case describes a 1GWh energy-storage distribution project with an overseas power enterprise in Southeast Asia. The project served residential and industrial and commercial users, addressed unstable power grids and high electricity prices, and included local after-sales service centers. This case supports reviewing production consistency, environmental suitability, and service documentation when the controller is supplied within a broader energy-storage solution.
