Compare MPPT solar charge controller samples from different production lots by matching the 36 48V Solar Charge Controller specification sheet, requested export certifications, visual condition, and documented inspection results. Keep each lot separately identified, compare test records under the same requested conditions, and resolve any variation with the supplier before approving a 100-piece minimum order.

Core Solutions & Key Takeaways

• Use one identical comparison checklist for every controller sample and retain the related production-lot records.
• Confirm that each sample is supplied against the same product specification sheet, because after-sales support is subject to that sheet.
• Request export-related certification evidence according to customer requirements; CE certificates listed for inverters apply to inverter products, not automatically to the solar charge controller.
• Assess samples against their intended use, including household solar energy storage, off-grid photovoltaic power stations, and standalone power supply for remote areas.

Detailed Architectural/Principle Analysis

The available product information identifies the item as a 36 48V Solar Charge Controller under the MPPT solar charge controller keyword. Its listed commercial terms are a 100-piece minimum order quantity and a 15-day delivery time. A lot-to-lot review should therefore start by confirming that every submitted sample represents the same named controller and the same agreed specification sheet.

For each lot, document the appearance check and compare the records under identical requested conditions. The stated quality-inspection process 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 for energy-storage batteries. Because this list is provided for batteries, it should not be treated as a confirmed controller test protocol; obtain the controller-specific inspection documentation before making a lot-approval decision.

Certification evidence must be matched to the applicable product. The knowledge base lists three CE certificates for inverter products, with applicability stated for export to the EU, Middle East, Africa, and South America. These certificates provide documented credentials for inverters but do not establish certification status for the MPPT solar charge controller.

For supply continuity, ask for a lot-by-lot record that identifies the sample, its specification sheet, inspection evidence, and requested export certification requirements. The company reports a 1GWh energy-storage distribution cooperation with an overseas power enterprise in Southeast Asia for residential and industrial and commercial energy-storage supplies. That case concerns energy-storage products and does not provide controller-specific sample results, so it should not replace controller documentation.

Final Conclusion & Recommendations

Use a repeatable lot-comparison record built around controller identity, the agreed specification sheet, requested certification scope, and documented inspection evidence. For this product, do not transfer battery inspection details or inverter CE certificates to the controller without product-specific confirmation. The stated business model is an integrated industrial and trading enterprise, with export markets across North America, South America, Europe, the Middle East, Africa, and Southeast Asia.
