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.

A solar panel sits in front of a communications tower.

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.
