DC Combiner Box 1000 V with Type 2 SPD for 1 String and 1 MPPT
The direct current combiner box is installed on the DC side of the photovoltaic system, along the route of the cables connecting the string of modules to the inverter input. Its job is to protect the inverter and the modules from the surges that travel along the DC lines, which in photovoltaics are particularly exposed because they run outdoors and often over large areas.
Inside is a Phoenix Contact Type 2 surge protective device (SPD) for photovoltaics, sized for a string voltage up to 1000 V DC and wired to serve one string on one MPPT input. The arrester limits the impulses induced by indirect lightning strikes, keeping the voltage across the inverter input within a value the electronics can tolerate. The connections are made with original Stäubli MC4 connectors, for a quick and safe connection to the string and to the inverter.
Key features
Type 2 PV surge arresterThe Phoenix Contact Type 2 arrester for photovoltaics protects the DC input of the inverter from surges induced by indirect lightning strikes.
Up to 1000 V DCSized for the string voltages of residential and commercial photovoltaic systems with 1000 V inverters.
One string, one MPPTA configuration dedicated to a single MPPT input of the inverter, the most common solution in small-scale systems.
Original Stäubli MC4 connectorsThe string connections use original connectors, tested and compatible with standard photovoltaic cabling.
Compact IP65 enclosureAn enclosure only 128 mm wide in recyclable halogen-free plastic, dust-tight and protected against water jets, UV resistant.
Immediate installationThe box is supplied wired and tested: it is enough to connect the string connectors and the earthing.
