VRH Lightning Protection offers a comprehensive range of advanced earthing solutions designed to provide optimal protection against lightning strikes and electrical faults. Our products are engineered to ensure reliable electrical conductivity, enhance safety, and comply with international standards.
Comprehensive Power Distribution
ACDB (AC Distribution Box) and DCDB (DC Distribution Box) are essential components in solar power systems, designed to manage, protect, and isolate electrical circuits on the AC and DC sides of the system. They play a critical role in ensuring safe distribution of power from solar panels to inverters (DCDB) and from inverters to the load or grid (ACDB).
Both units are equipped with protective devices such as MCBs, MCCBs, surge protection devices (SPDs), isolators, and fuses, offering full-scale safety and system control. Housed in robust, weatherproof enclosures, they are ideal for rooftop, ground-mounted, and utility-scale solar installations. The design is modular and customizable as per system capacity and voltage requirements.
