Solar PV DC Combiner Box 4-In 4-Out 1000V | Voltacon

This pre-wired solar PV DC combiner box handles 4 string inputs and 4 protected outputs, rated to 1000VDC. It combines string overcurrent protection, surge protection and DC isolation inside a single IP65 enclosure, making it a compact way to bring multiple PV strings together before they reach the inverter.

Key features

• Inputs and outputs, 4 fused string inputs and 4 protected outputs
• Maximum voltage, 1000VDC
• Surge protection, DC SPD fitted per output
• Isolation, DC isolators included
• Enclosure, IP65 weatherproof rating
• Fusing, string fuses with LED indicators
• Glanding, cable glands included

Applications

Used for DC string protection on residential and commercial solar PV systems. It also works as a combiner box feeding a 4 MPPT output inverter, gathering multiple strings into a protected set of outputs.

Installation and safety notes

DC solar circuits carry dangerous voltages. Installation must be carried out by a qualified electrician, and all PV strings should be isolated before anyone works on the internal connections.
