Top 5 Considerations When Choosing a Telecom Battery

by Matt Maroon on February 21, 2017 at 4:54 PM

With continued worldwide growth in cell phone subscribers, data usage, and network upgrades, the need for reliable power throughout the telecommunications network has never been more crucial.  

There are several layers that provide this reliable power - the traditional utility grid, generators, renewables, and batteries.  Even in the most reliable grid installations, batteries are a fundamental element of the ‘belt-and-suspenders’ approach to ensuring 100% uptime for tower owners and operators.  For weak-grid sites, batteries are indispensable for providing power to bridge during times when the grid is unavailable.  And in full off-grid installations, batteries are the key to enabling reliability and the lowest operating expenses.

While specific battery bank sizing will vary in these three scenarios (on-grid, weak-grid, off-grid), there are still some common attributes that are high on the wish list of tower operators, owners, and energy service companies.


Partial State of Charge and Solar Telecom Batteries

In off-grid telecom sites with energy storage, the solar batteries are usually sitting at a partial state of charge, meaning they are not fully charged, nor fully discharged.

Solar-powered telecom towers commonly have lead acid batteries for their energy storage systems. However, operating or even sitting idle at a partial state of charge is problematic for lead-acid batteries.  As lead acid batteries discharge, the active materials transform from lead to lead sulfate - it is this chemical reaction that provides the requested power.  


Grid Power, Telecom Tower, and Battery Kilowatt-Hours: Shanghai Installation Leads the Way

by Paul Ruggiero on February 5, 2017 at 10:00 AM

I recently wrote about how off-grid, solar telecommunications towers are starting to use energy storage to extend the reach of communication networks. Grid-tied towers are starting to get in on distributed energy generation, too. One such tower in Shanghai recently added solar power and Aspen energy storage. What can solar batteries do for a telecom tower with reliable grid power? More than you might think.
