Saft Sunica rechargeable nickel-cadmium batteries are designed to provide the optimum energy storage solution for renewable energy applications such as photovoltaic and wind-power systems.
Saft Sunica rechargeable nickel-cadmium batteries are designed to provide the optimum energy storage solution for renewable energy applications such as photovoltaic and wind-power systems.
They offer a number of important advantages compared with standard batteries including high efficiency, reliability, long service life and the potential for both shallow and deep cycling.
Sunica batteries are ideally suited for a wide variety of remote installations including navigational aids, telecommunications, rail signalling, oil and gas platforms and electric utilities.
Photovoltaic and renewable energy systems require efficient batteries with a long cycle life and the potential for both shallow and deep cycling depending on the application and the ambient temperature range.
Saft Sunica batteries are designed specifically to offer a number of key advantages in this type of application, namely: constant charging efficiency over time; continuous operation at any state of charge; minimal self-discharge rates; a high available performance even at very low states of charge; sustained efficiency even at high or low temperatures; and a long cycle life, even when the charge/discharge cycle involves 100% depth of discharge.
Sunica batteries feature a robust pocket plate construction and shock-resistant polypropylene casing material to ensure they can withstand all the harsh treatment expected during transportation over difficult terrain.
An extra electrolyte reserve ensures almost supervision-free service and a long interval between topping-up.
They also benefit from the long service life of nickel-cadmium technology, with no risk of the "sudden-death" failure found in lead-acid batteries, and are expected to have a lifetime of up to 20 years.
The full cost-effectiveness of Saft Sunica batteries becomes evident over their 20-year lifetime, during which a lead-acid battery, with a typical five-year lifetime, would require three replacements.
With no manpower or equipment expenses for battery replacement, minimal maintenance and reduced need to travel to often remote installations Sunica batteries will significantly lower the life cycle cost of the battery and the renewable energy system as a whole.
