Rated voltage up to 600V DC, suitable for residential and light commercial string inverter systems.
Integrated DC fuses, isolation switch, and Type II surge protection help reduce the risk of DC faults and inverter damage.
IP65 enclosure with sealed structure designed for outdoor environments exposed to rain, dust, and humidity.
Finger-safe internal structure improves installation and maintenance safety during field operation.
Internal Electrical Layout
Internal Layout & Reliability:Premium Copper Busbars: Uses high-conductivity copper connections to ensure low resistance and stable power transmission.
Thermal Optimization: Internal spacing is engineered to minimize heat accumulation under continuous full-load outdoor operations.
Safe Load Isolation: The rugged DC switch allows full-load disconnection for emergency shutdown or routine system maintenance.
Protection & Reliability
Built-in protection functions include:
DC overcurrent protection
Short-circuit isolation
Photovoltaic surge protection
Grounding protection
Internal electrical spacing and wiring layout are designed to reduce heat accumulation and improve long-term connection stability under continuous outdoor operating conditions.

Applications
Residential Rooftop Solar Systems: Protects and simplifies small-scale home solar installations.
Dual-MPPT Single-Phase PV Projects: Perfectly matches dual-MPPT inverters by separating or combining string inputs.
Small Commercial Solar Arrays: Scalable solution for small business offices, farms, and workshops.
Off-Grid Solar & Energy Storage Installations: Provides crucial DC side protection for battery-charging solar subsystems.
