A dual-string DC distribution box built for 6kW to 10kW solar systems running two independent MPPT strings. Each string is protected on both the positive and negative legs by 600V DC fuses housed in finger-safe holders, giving high-breaking-capacity short-circuit protection where DC faults are hardest to interrupt. Two Type-2 600V surge protective devices divert lightning and switching transients safely to earth before they reach the inverter. Housed in a compact IP65-rated polycarbonate enclosure with cable glands, clear labelling, and DC polarity marking. Built with Elmex components throughout. Supplied in bulk; custom configurations on request.

FAQs:
- What system size is this for? 6kW to 10kW dual-MPPT solar PV systems.
- Why four fuses for two strings? Each string is fused on both the positive and negative legs for full DC-side protection.
- What are finger-safe holders? Enclosed fuse holders that prevent accidental contact with live parts during servicing.
- Fuse or MCB — which should I choose? Fuses give high-breaking-capacity short-circuit protection at lower cost; MCBs are resettable on site. We supply both versions.
- Outdoor safe? Yes, IP65-rated.
- Bulk/custom orders? Yes — message us on WhatsApp.
