Factory Strength & Capability
How we select, audit and inspect your order — before the container is sealed.
Who We Are
Sunterra is the export brand of Hebei Ruonanfeng Trading Co., Ltd. We are a sourcing and supply-chain partner, not a factory: instead of pushing whatever one plant happens to make, we screen specialist solar lighting manufacturers in Zhongshan, Shenzhen and Dongguan and consolidate the best matches into a single order.
Our team covers sourcing, QC, documentation and export logistics. We inspect incoming components, monitor production at the partner plant, run battery and photometric sampling tests, and carry out pre-shipment inspection on every order — so distributors, contractors and project buyers in Southeast Asia, the Middle East, Africa, Europe and Latin America receive one consolidated, fully documented shipment. Every batch is traceable from cell lot to final inspection record.
What We Verify Before Shipment
- Driver and control board construction and protection
- Integrating-sphere photometric report per model
- Battery capacity and cycle-life sampling test
- IP65 / IP66 spray and dust ingress test report
- All-in-one and split-unit assembly QC checklist
- Retail-box and export carton packing inspection
Every order ships with a batch number linked to its battery lot and inspection records.
