Description

Phoenix Contact SOL-SC-2ST-0-DC-1MPPT-2000 is the ideal generator junction box for anyone looking to reliably protect their photovoltaic system against surge voltages. This junction box connects two strings to one MPP tracker and is rated for system voltages up to 1000 V DC. This ensures your system's DC side is protected in a compliant and durable manner.

Key Benefits for Your System

Reliable surge protection: The integrated Type 2 surge arrester with a protection level of ≤ 4.2 kV protects your solar system from voltage spikes.
Quick installation: Push-in connectors and pre-fitted cable glands enable fast commissioning.
Compliant combination: The junction box meets the requirements of DIN EN 61439-2 for power switchgear and controlgear assemblies.
Weatherproof enclosure: With IP65 protection rating and an operating temperature range of -20 °C to 55 °C, the box is suitable for outdoor use.

Safe DC Cabling for Your Photovoltaic System

A generator junction box bundles the DC strings of your photovoltaic system and safely routes them to the inverter. The SOL-SC-2ST-0-DC-1MPPT-2000 from Phoenix Contact accommodates two strings and routes them via one MPP tracker. The integrated Type 2 surge protection shields your valuable solar equipment from indirect lightning strikes and transient overvoltages. The protective equipotential bonding conductor is cleanly looped through and connected to the local equipotential bonding system. Whether for a small rooftop installation or a large ground-mounted system – this generator junction box from Phoenix Contact provides a solid, compliant foundation for safe and trouble-free operation of your PV system.
