Highlights
400W Peak Output & Up to 25% TOPCon Efficiency
Powered by high-efficiency TOPCon monocrystalline solar cells, the SP400 Pro delivers up to 400W peak power with conversion efficiency of up to 25% and a 39.1V open circuit voltage, providing efficient solar charging for compatible portable power stations.
Bifacial Design with 10–15% Extra Real-World Power
The bifacial design captures sunlight from both sides, using reflected light from the rear to increase real-world power generation by 10–15% under suitable conditions. Actual gains vary with the surrounding surface, reaching up to 24.85% on highly reflective surfaces such as mirrors.
IP67 Waterproof & Rugged Outdoor Construction
Featuring an IP67-rated panel body, rigid aluminum frame and thick plastic corner guards, the SP400 Pro is built for demanding outdoor environments. It operates reliably from -10°C to 70°C for year-round outdoor use.
Foldable Design with 35° Integrated Kickstand
The 9kg panel folds to 691 × 790mm for easier transport and storage. Its integrated 35° kickstand provides a convenient setup angle for efficient solar exposure without requiring additional tools.
Wide Compatibility & Up to 800W Expandable Power
Equipped with standard MC4 connectors and an included MC4-to-XT60 solar charging cable, the SP400 Pro is compatible with 90% of mainstream portable power stations. Series and parallel connections are supported, with two panels in series reaching up to 800W peak power.
