Conventional battery systems used in telecommunication cell sites are designed to act as backup devices for infrequent 5-20 short duration or interruptions per year. They do not tolerate frequent and deep cycling.

Prudent Energy has developed an enhanced 5kW-8hour deep cycling storage system aimed at allowing off-grid or weak grid telecommunication sites to be cycled repeatedly or integral in an HYBRID form with wind or PV.

This builds on the proven two VRB-ESS units operating in Africa and can deliver 1 year payback by reducing O&M costs, diesel usage extending diesel engine life and being less sensitive to temperature variation.
