Cell-Phone Tower Power System Prototype Testing for Verizon Wireless

For Verizon Wireless, NREL tested a new cell-phone tower power system prototype based on DC interconnection and photovoltaics (PV) rather than an AC interconnection.

To validate an all-DC design solution based on PV, batteries, and DC cooling systems, the testing simulated environments over the range of temperatures specified for Verizon's telecommunications equipment. For testing, NREL used a large, walk-in environmental chamber at its Energy Systems Integration Facility (ESIF).


NREL's testing will help enhance the reliability and cost effectiveness of Verizon's new cell-phone tower power system.
