DC Combiner Box 1000 V with Type 2 SPD for 2 Strings and 2 MPPT
The DC combiner box is installed on the DC side of the photovoltaic system, between the module strings and the inverter inputs. This version is wired for two independent strings on two separate MPPT inputs: the strings remain electrically distinct, so each one can work at its own maximum power point even with different orientations, tilts or shading.
Protection is provided by two Phoenix Contact Type 2 surge protective devices (SPD) for photovoltaics, one for each string, rated for a working voltage of up to 1000 V DC. The surge arresters divert to earth the impulses induced by indirect lightning strikes, limiting the residual voltage at the inverter inputs. The string connections are made with original Stäubli MC4 connectors.
Key features
Two strings, two MPPTsEach string keeps its own maximum power point tracking: ideal for roof pitches with different orientations or shading.
Two Type 2 surge arrestersOne Phoenix Contact surge protective device per string protects both DC inputs of the inverter against induced surges.
Up to 1000 V DCRated for the string voltages of photovoltaic systems with 1000 V direct current inverters.
Original Stäubli MC4 connectorsQuick and safe connections, compatible with standard photovoltaic cabling.
Weatherproof IP65 - IK08 enclosureHalogen-free recyclable plastic enclosure, resistant to UV rays and impact, suitable for outdoor mounting.
Supplied wired and testedThe box is ready to use: installation times and the risk of errors are reduced compared with assembly on site.
