A dual-string DC distribution box built to protect 6kW to 10kW solar PV systems with two independent MPPT strings. Each string gets its own C32 DC MCB for overcurrent protection plus a Type-2 SPD for surge suppression, so a fault or surge on one string is isolated from the other. Housed in a rugged IP65 TRIBOX enclosure with clear labelling, cable glands, and proper earthing, it’s made to sit outdoors through heat, dust, and monsoon. Supplied in bulk with quality branded components; custom configurations on request.
