Weidmüller Generator Connection Box 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.
