Eliminating Generator Runtime for AT&T Off-Grid Cell Tower

Supercapacitors reduce operating costs vs. VRLA

Eliminating Generator Runtime for AT&T Off-Grid Cell Tower

Supercapacitor ESS Reduces Generator Runtime by 70%

Genset Runtime

  • Before – 8.5 hours/day
  • After – 2 hours/day
This site is under 10' of snow from November to May. With lead acid batteries we would have run out of fuel by January and wouldn't be able to keep the site on air. With the supercaps, we only refuel the generator tanks 1 time per year and it's only 1/2 empty when we do. We could not keep this site going year around without supercaps.
