AC cycling system


Gen-sets with AC alternators have been perceived as a market standard for many years and are still being used extensively across the world. Nevertheless, where AC systems have been traditionally used as an AMF solution, the new market trend tends to utilize 48V batteries as primary backup power source, charged by mains – if available – or the gen-set itself. This, so-called cycling operation, reduces running time of the gen-set and therefore rapidly decreases OPEX by saving fuel.

ComAp Solution

ComAp’s InteliLite Telecom continuously controls and monitors the BTS’s gen-set to charge a battery bank that is used as the main source of power to the load. Once the 48V battery is charged to the optimum level, the controller starts/stops the gen-set according to the battery voltage using the integrated Battery Cycling System. There are many remote communication capabilities available with the addition of modules IB Lite for ethernet communication, or IL-NT GPRS for GPRS communication. ComAp’s WebSupervisor is an excellent tool allowing for further remote monitoring and control of the BTS site via internet from any laptop or portable device.


  • Sunpower AC cycling system including InteliLite Telecom offers significant OPEX savings
  • Start/Stop based on battery bank voltage ensures the telecom tower is always powered most efficiently
  • Generating-set only used to charge batteries meaning reduced run-hours and smaller cost-effective generating-set can be used
  • Remote monitoring for optimal service intervals, fault reporting and reduced operating costs (OPEX)

Scope of supply:

  • InteliLite Telecom (gen-set control unit)
  • IB-Lite (ethernet communicaion plug-in module) or IL-NT-GPRS (GPRS communication plug-in module)
