Hybrid Power Generation

Hybrid Power Generation

Telecommunication operates in Africa, India and other developing countries face severe changes in powering mobile bas stations (BTS) sites in remote areas. In many cases the sites are simply too far from the AC grid for AC mains powering to be economic. Other sites have AC power, but it is extremely unreliable. These sites are often powered by small diesel generator sets, running continuously. Sealed lead acid (VRLA) batteries provide backup power to generator maintenance, start up and cover the occasional case when fuel runs out. Ongoing costs are high and include Direct fuel cost, truck rolls, refueling is usually needed every one or two weeks at a high cost for every remote site. Generator maintenance. Generator replacement. In continuous duty a small generator may only last two years. By changing the way, the generator is controlled, an operator can achieve significant savings in running costs. This is referred to as “hybrid operation”, where the generator only runs part of the time, and the battery runs the load while the generator is off. For that purpose, we offer our range of hybrid power solutions that are fully customized to fit every customer’s need or request, to reach maximum efficiency
