DC Combiner Box 1000 V with Dehn 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. It is wired for two independent strings on two separate MPPT inputs, so that each one can work at its own maximum power point even with roof pitches of different orientation or tilt.
Surge protection is provided by a Dehn Type 2 surge arrester for photovoltaics rated for 1000 V DC. Dehn arresters in the photovoltaic range use pluggable discharge modules with an integrated short-circuiting and disconnection device (SCI), a combination of thermal disconnector and short-circuit switch that prevents direct current arcs from striking even at the end of the varistor's service life. The front status indicator shows at a glance when a module needs replacing.
Key features
Dehn Type 2 surge arresterProtection against surges induced by indirect lightning strikes on both DC inputs of the inverter.
Dehn SCI technologyThe integrated short-circuiting and disconnection device prevents direct current arcs from striking at the end of the varistor's life.
Two strings, two MPPTsThe two strings remain independent: each one keeps its own maximum power point tracking.
Pluggable modules with status indicationThe discharge cartridges are plug-in, with a front status indicator: replacement is immediate and requires no rewiring.
Up to 1000 V DCRated for the string voltages of photovoltaic systems with 1000 V direct current inverters.
Weatherproof IP65 - IK08 enclosureHalogen-free recyclable plastic enclosure, dust-tight and protected against water jets, resistant to UV rays and impact.
