DC Combiner Box 1000 V with Type 2 SPD for 1 String and 1 MPPT, 12-Module Enclosure
The direct current combiner box is installed on the DC side of the photovoltaic system, between the string of modules and the inverter input, to protect the system from the surges that travel along the DC lines. This version is built in a 12-module DIN enclosure, roomier than the compact variants of the same series: the free space inside makes wiring, cable routing and the possible integration of additional devices easier during installation.
Inside is a Type 2 surge protective device (SPD) for photovoltaics, sized for a string voltage up to 1000 V DC and wired for one string on one MPPT input. The arrester diverts to earth the impulses induced by indirect lightning strikes, limiting the residual voltage at the inverter input to values compatible with its impulse withstand.
Key features
Type 2 PV surge arresterProtects the DC input of the inverter and the modules from surges induced by indirect lightning strikes and atmospheric phenomena.
Up to 1000 V DCSized for the string voltages of photovoltaic systems with 1000 V direct current inverters.
12-module enclosureThe larger enclosure (319 × 259 × 144 mm) leaves room for tidy wiring and for any additional devices on the DIN rail.
One string, one MPPTA configuration dedicated to a single MPPT input of the inverter.
Watertight IP65 - IK08 enclosureAn enclosure in recyclable halogen-free plastic, resistant to UV rays and impacts, suitable for outdoor mounting.
Supplied pre-wiredThe box arrives assembled and tested, cutting installation times and the risk of errors on site.
