A dual-string DC distribution box built for 6kW to 10kW solar systems running two independent MPPT strings. Each string gets its own 32A 600V DC MCB for resettable overcurrent protection, plus a Type-2 600V surge protective device — so a fault or surge on one string is isolated from the other and kept away from the inverter. Housed in a compact IP65-rated polycarbonate enclosure with cable glands, clear labelling, and DC polarity marking, it’s made to sit outdoors through heat, dust, and monsoon. Built with L&T MCBs and Elmex protection components. Supplied in bulk; custom configurations on request.

FAQs:
- What system size is this for? 6kW to 10kW dual-MPPT solar PV systems.
- Why 2 in 2 out? Two independent strings, each with its own MCB and SPD, so a fault on one string doesn’t affect the other.
- What’s the MCB rating? Two 32A, 600V DC, resettable C-Curve MCBs.
- Why polycarbonate? Lightweight, impact-resistant, and non-conductive — well suited to outdoor DC enclosures.
- Outdoor safe? Yes, IP65-rated.
- Bulk/custom orders? Yes — message us on WhatsApp.
