Frequently Asked Questions (FAQs)

What is the minimum order quantity (MOQ) for factory-direct solar fridges?

We keep minimums flexible to support both growing regional distributors and large commercial enterprise projects. For standard stock models, our sample and trial order MOQ starts at just 5 to 10 units. For custom OEM runs and maximum cost savings, our solar fridge bulk order wholesale 12V DC fridges program delivers optimized tier pricing at full 20ft and 40ft HQ container volumes.

Can I customize voltage configurations and private label branding?

Yes. As a direct manufacturer, we offer full OEM/ODM production capabilities. You can specify custom exterior paint finishes, add private label silk-screened logos, and customize power configurations—including standard 12V/24V DC, high-voltage 48V DC systems, or integrated dual AC/DC auto-transfer switches for hybrid grid backup.

How do direct-drive DC solar refrigerators operate without an inverter?

Our direct-drive units wire directly into your solar PV panel array or DC battery bank. Using variable-speed DC compressors, these systems run natively on direct current, completely bypassing the need for a standard AC inverter. Eliminating DC-to-AC power conversion cuts energy losses by 15% to 20%, lowering total thermal draw and reducing your required solar panel array size.

What warranty and spare parts support are available for bulk B2B orders?

We back our production lines with a 3-year warranty on compressors and a 1-year complete system warranty. For volume commercial shipments, we include a 1% to 2% quick-wear spare parts package (digital controllers, wire harnesses, fan motors, and thermal sensors) right inside your container shipment.
