Abstract :
DC Power Systems have been used in Telecom operations for decades because of their unsurpassed ability to provide un-interruptible power. The use of DC with battery backup minimizes the possibility of power failure and redundant elements maximize system reliability. When operating an off-grid site, all of the energy must be produced locally. As renewable sources are intermittent, energy storage must be employed. Energy storage options are abundant, but each has its own set of challenges and requirements. Whether operating temperature, depth of discharge limitations or simply size, all aspects must be considered. Locally generated power must be converted into usable power (48V or 24Vdc) without excessive conversion and storage losses.
