A power system is designed for providing reliable electrical power to a telecommunications facility and/or associated devices. The system includes a DC bus adapted to receive electrical power from a primary energy source. A switch is provided for switching from the primary energy source to a secondary energy source. Additionally, the system includes one or more capacitors electrically connected into the DC bus. The one or more capacitors hold a charge so that power is maintained to the DC bus as a switch is made from the primary energy source to the secondary energy source.
