PV DC Combiner Box 8-In 2-Out 1000V IP65 | Voltacon

This pre-wired solar PV DC combiner box takes 8 fused string inputs and combines them into 2 independent protected outputs, suited to dual MPPT inverters. It comes with fused PV string terminals, a surge protection device and DC isolators fitted inside an IP65 enclosure, rated to 1000VDC.

Key features of this pv dc combiner box

• Configuration, 8 fused string inputs, 2 independent outputs (4 strings per MPPT)
• Maximum voltage, 1000VDC
• Maximum DC short circuit current, 15A per string, configurable
• Maximum output current, 40A per MPPT
• Protection fitted, fused string terminals, SPD and DC isolators pre-installed
• Enclosure, IP65 weatherproof

Applications

Designed for DC string protection on commercial solar PV systems using dual MPPT inverters. It combines 8 strings into two independent MPPT charger inputs, so each MPPT input on the inverter receives its own protected feed from 4 strings.

Installation and safety notes

DC solar circuits carry dangerous voltages. This box must be installed by a qualified electrician. Isolate all PV strings before working on internal connections.
