News -1 Innovation Alert: Pre-Potted 3-Split Solar Panel Junction Box Eliminates Manufacturing Hurdles
author: Koko
2025-12-11
High-power 500W-750W solar modules rely on 3-split potting solar panel junction boxes for cost savings (30% less material vs. integrated types) and better heat dissipation—yet on-site potting adds steps, cuts efficiency, and forces small-to-medium manufacturers to invest in expensive automation.
Our Pre-Potted 3-Split Solar Panel Junction Box solves this: retain split-type advantages with factory-sealed pre-potting for direct assembly.
Core Benefits in Brief
✅ 40% Faster Production: No on-site potting—mount and connect instantly (skip dispensing/curing steps)
✅ Consistent Reliability: ISO 9001-controlled pre-potting (3.7ml thermal silicone), IP68 waterproof, IEC 62790/UL 3730 compliance
✅ Cost & Performance: 1500V/20A~30A+ rating, 6mm busbar spacing, dual-side outlets (50% shorter cables), -40°C to +85°C operating range
