Hybrid System at Verizon Base Station Gives New Meaning to 'Peak Power'



Richardson (News - Alert), Texas-based Eltek, a provider of high-efficiency power systems, has completed an off-grid hybrid solar-propane DC power system installation for Verizon Wireless (News - Alert). The company has installed a Flatpack2 High Efficiency (HE) system at the U,S. wireless carrier’s base station in Bear Mountain, California – a remote installation that serves both local residents and a large population of recreational hikers and outdoor lovers.

The base station has no access to utility power. Previously, propane generators and a 20-year-old hybrid solar power system had been used by Verizon to keep it running around the clock. The Eltek system immediately boosted solar power production, cutting the amount of time the generators had to run from 18 hours to less than four hours per day.

The Flatpack2 HE hybrid solar power system includes the Flatpack2 HE solar converter, the Flatpack2 HE rectifier and the Smartpack controller. The Flatpack2 HE solar converter connects to the solar panels and converts the solar power into a regulated 48VDC for supply to the telecom equipment.

Eltek describes the key features of the platform as:

  • Proven reliability
  • Remote control and monitoring
  • Built-in Web server
  • Configuration storage, copy and upload capability
  • Scalability
  • Solar-energy prioritized
  • Diesel generator monitoring and control for reduced and optimized fuel usage

Verizon called on Eltek to deploy the system, as well as to manage the entire power infrastructure including the inverters, rectifiers, generators and battery recharging. The new system also dramatically reduces maintenance costs for Verizon, allowing the wireless carrier’s personnel to receive continual status updates about the site.

 “Solar power can play a significant role in powering telecom sites where it can be engineered to significantly reduce the operating expenses and maximize power output,” commented David Leal, Eltek’s vice president of North American Sales. “What Verizon has done at the Bear Mountain site shows the possibilities for telecom solar throughout the United States.”
