Benefits

On off-grid operation conditions, our DC 48V variable speed alternator can fulfill two roles with just one machine:  

  • Power supply of the cell tower, acting as a standard standby genset
  • Hybrid cell tower installation battery charging 

This technology can help reduce fuel consomption by up to 36% vs. a standard, diesel-only setup

The Variable Speed LSAVS alternator integrates two special components:

  • ​A dedicated Automatic Voltage Regulator (R220-VSG) and rectifier that allows the alternator to deliver constant DC Voltage Output at two different speed.
  • An integrated load control module (CCM) to manage battery charging. All battery types are supported (OPzV, SBS EON, EXIDE, A600 and Evolion)​
