NREL and Verizon Validate New All-DC Design Solution for Telecommunications Facilities

Network equipment is all DC, so rather than relying on conventional AC power, Verizon is working with NREL to validate a new design solution that employs PV and batteries and new DC cooling systems.

The new design will ease utility interconnection by connecting PV to the DC bus and batteries, increase resiliency by allowing PV to contribute—and cooling to continue—in a power outage, lower costs with day-to-day utility cost savings, and increase efficiency through reduced part count and fewer power conversions from DC to AC.
