Direct Current (DC) Power Solutions for LED Lighting Systems
Utilization of Class 2 low voltage DC wiring eliminates the need for power packs, junction boxes, and conduit to luminaires, providing reductions of both materials and related
Direct current (DC) electricity has the potential to improve the resiliency, reliability, and energy efficiency of building systems, specifically in the context of DC lighting and building microgrids.
DC power is directly connected to the DC building loads such as HVAC systems and electric vehicle chargers after being distributed through the building. Typically, 380 V DC is used to power large building loads.
For energy storage systems that are also connected to solar energy, there is an option to have the energy storage system be DC (direct current) coupled. Since solar generation systems create DC electricity, it is often most efficient to have this go directly to the batteries (via a DC-DC converter) as DC energy.
Some building loads such as large fans and HVAC compressors require AC electricity to operate, while others including computers, electronics, and LED lighting require DC electricity.
