The TOMZN HT 8WAY IP65 Photovoltaic Distribution Box is a professional DC solar combiner box designed to provide complete protection and distribution for photovoltaic (PV) systems, battery energy storage systems, DC charging stations, and industrial DC power applications. With its IP65 waterproof enclosure, integrated DC MCB, fuse protection, and surge protection device (SPD), this combiner box ensures reliable and safe DC power distribution in both indoor and outdoor environments.

Designed with a 1 Input 1 Output configuration, the distribution box supports 600VDC systems with selectable current ratings from 16A to 63A. The integrated three-in-one protection system combines overload protection, short-circuit protection, and lightning surge protection into a compact enclosure, reducing installation complexity while improving system safety.

The rugged weatherproof enclosure protects electrical components from dust, moisture, and water jets, making it ideal for rooftop solar installations, off-grid solar systems, battery storage systems, and industrial DC distribution panels. BDTronics supplies genuine TOMZN photovoltaic distribution boxes in Bangladesh for residential, commercial, and industrial solar power installations.
