Situation
As subscriber penetration is rising, mobile network coverage is spreading to ever more remote locations – typically with no grid supply – which is why telecom tower operators need to seek cost effective solutions for providing power to their BTS. Without the main power supply, off-grid power systems rely purely on direct current (DC), which is why popularity of DC gen-sets has been growing recently. Avoiding the unnecessary rectfication, batteries can be charged directly from the DC generator while powering the load simultaneously. In fact, the whole BTS application can be powered by one controller – ComAp’s InteliLite Telecom DC.
