Weidmüller Generator-Anschlussbox PVI DC 1I 1O 2MPP SPD1 MC4 10

DC combiner box engineered for photovoltaic installations with two MPP trackers, each accepting one input string. The integrated Type 1+2 surge protection and 4-pole DC disconnect switch safeguard the array up to 1000 V DC, while pre-assembled MC4 connectors cut commissioning time on site.

Advantages

All critical DC-side protection in a single IP65 enclosure: surge arresters, disconnect switch, and cable entry glands. The UV-resistant polycarbonate housing withstands harsh rooftop and ground-mount environments, and the unfused design reduces maintenance points without compromising safety at 15 A per string.
