Performance Features
Advanced Circuit Protection
Every unit comes pre-fitted with high-voltage DC circuit breakers. These heavy-duty breakers provide reliable thermal-magnetic tripping to protect your PV strings from backflow and overcurrent, significantly reducing the risk of electrical fires.
Specialized PV Surge Arresters
To safeguard your expensive inverter from atmospheric disturbances, our combiner box includes a dedicated DC Surge Protective Device (SPD). It effectively redirects high-voltage surges caused by lightning strikes safely to the ground.
Thermal Management & Durability
Constructed from flame-retardant, high-impact materials, the enclosure is designed to dissipate heat efficiently. It remains structurally sound in temperatures ranging from -25 °C to +60°C, ensuring performance during peak summer solar production.
Plug-and-Play Installation
Pre-Wired Internal Layout: Saves up to 50% on installation time
Waterproof Cable Glands: High-tension glands ensure a perfect seal around DC cables
Transparent Inspection Window: Allows technicians to verify breaker status without opening the main seal, maintaining the internal IP rating
Key Applications
Residential Rooftop Solar: Consolidate wiring from multiple panel arrays into a single down-lead
Off-Grid Energy Systems: Protect battery charging circuits and solar controllers
Commercial Solar Farms: Scalable solution for managing high-current distribution
EV Charging Integration: Safe DC management for solar-integrated vehicle charging stations
Safety & Quality Assurance
UV Resistance: Tested for 1000+ hours of direct UV exposure to prevent material brittleness
Corrosion Proof: Ideal for coastal or high-salinity environments where metal boxes often fail
Anti-Theft Design: Features a lockable latch system to protect internal components in public or remote locations
