Off-grid Commercial Office DC Grid System

A hybrid AC and DC platform that is being designed as an open architecture focused on reducing or eliminating inefficient AC to DC conversions between power sources and light sources by converting and distributing power in DC. This platform is designed to improve reliability and energy efficiency across all areas of commercial buildings. Replace existing Alternating Current (AC) fed ceiling in a commercial office with a Direct Current (DC) micro grid that can be fed via Photovoltaic panels installed on the building or via a utility fed inverter. This field evaluation is phase one of a multiphase project that aims to evaluate performance and provide proof of concept of a DC fed lighting system, vending machine and a ventilation system. This phase will provide proof of concept of DC ceiling in addition to evaluating the performance of the system.
