OEM Outdoor PV DC Distribution Cabinet Maximum Power Point Tracking
Product Describe:
1. Utility-Scale Solar Farms
Function:
Centralizes DC power from multiple PV strings before inverter
input.
Provides overcurrent/arc-fault protection (e.g., 1000V/1500V DC
fuse holders).
Features:
IP65-rated enclosures (dust/waterproof).
Corrosion-resistant materials (e.g., stainless steel for coastal
areas).
Integrated string monitoring (per-channel current/voltage detection
via RS485).
2. Industrial & Commercial Rooftop PV
Function:
Reduces wiring complexity by combining 8–24 PV strings into one
cabinet.
Supports 1500V DC systems for higher efficiency.
Features:
Compact design (wall or ground-mounted).
Surge protection (40kA SPDs compliant with IEC 61643-31).
3. Floating Solar Plants
Function:
Handles high humidity and salt spray near water bodies.
Isolates faulty strings to prevent system downtime.
Features:
Enhanced sealing (IP66/IP68 options).
Cooling vents with anti-condensation heaters.
4. Desert/Arid Regions
Function:
Withstands extreme heat (>50°C) and sandstorms.
Features:
UV-resistant coatings.
Sand filters for ventilation openings.
5. Hybrid PV-Storage Systems
Function:Interfaces between PV arrays and DC-coupled battery
systems.
Features:
Dual DC inputs (PV + battery).
Isolation switches for maintenance safety.
