Solution Overview  

Off-grid diesel generator powered sites running continuously, cause glazing and carbon build-up in the generator engine and typically operate at an inefficient load range resulting in high fuel consumption.

The Power-One hybrid solution, by adding deep cyclic batteries significantly reduces generator runtime, fuel consumption operational expenditure due to less frequent maintenance intervals. Cyclic batteries also provides a degree of operational redundancy in the event of generator failure as the batteries are only ever discharged to a limited capacity on any given cycle, thus eradicating the need for a second generator.

Through the use of temperature hardened rectifiers and resilient batteries, the traditional requirement for air-conditioners can be traded in for a passive Heat Exchanger (HEX) or direct fan filter (DFC) cooling solution, which use significantly less energy. This energy saving equates to a lower total cost of ownership.

Battery and generator management is handled through the Power-One system controller, which, through the setting of battery type and capacity ensures optimal site management and maximum lifetime of the battery and generator.

The flexibility to expand using solar or wind converters allows prioritized renewable energy to be integrated into the modular system design.

Deployable using a wide range of existing indoor and outdoor power systems, the Power-One Hybrid Solution is the latest in a series of energy optimization innovations that Power-One is driving to help reduce total cost of ownership, while at the same time improving the environmental performance of mobile network growth worldwide.

Site Design and Modeling
Power-One’s comprehensive array of modeling and dimensioning tools allows the optimum Hybrid solution to be accurately specified based on power consumption, geographic location, financial and O&M data to suit a given CapEx/OpEx/ROI requirement.

System Components

Energy Resources and Storage

Deep Cyclic Batteries, with the capability to perform a large number of discharge and recharge cycles, is used to reduce the operating time of the diesel generator and improve operating fuel consumption. Batteries also store excess PV and wind energy for deferred use. Power-One carefully selects batteries designed for cyclic applications that provide a high rate recharge acceptance, high round-trip efficiency and high temperature resistance.

Solar Photovoltaic (PV) panels and Wind Turbines supply renewable energy to the site. Featuring low operating costs and carbon free energy production these resources provide a valuable energy source for remote sites or carbon conscious clients.

 
Site Management and Data Logging

Power-One Hybrid Controller HCC provides the essential function of managing battery and generator cycling, and ensuring maximum energy harvest of renewable energy sources through intelligent software controls. Fuel information from the generator is collected alongside battery and power data in order to provide complete statistics on the status and performance of the site. Site data is extended via alarm relays and remote Ethernet connection.

Power Conversion and Integration

Power-One AC/DC Rectifiers fed by a Diesel generator or AC Grid provide >95% conversion efficiency. Rectifiers incorporate resonant technology to reduce component stresses, providing increased system reliability. Rectifiers feature a wide input operating voltage range to maximize power availability within demanding utility power environments.

Power-One Solar and Wind converters provide isolated power conversion for PV arrays and wind turbines. Maximum energy harvest from the valuable photovoltaic (PV) array is accomplished through a patented 99.9% Maximum Power Point Tracking (MPPT) algorithm.

Hybrid Bus Architecture allows many modern Power-One Indoor and outdoor power systems the addition of a hybrid controller and optional PV/wind converters transforming them into a full hybrid solution.

Power-One Outdoor Cabinets feature aluminium construction, providing protection and thermal management in a range of harsh outdoor environments. Cabinets include complete AC distribution and earth connection points and houses the power system, DC distribution, system controller and provides space for mounting telecommunications equipment

Thermal Management: Low energy, passive cooling in the form of Heat Exchangers (HEX) or Direct Fan Cooling (DFC) provides extremely reliable thermal management for outdoor enclosures and shelters.
