SIEL in conjunction with Prism Power have recently completed the first phase of the installation of 56 off bespoke ‘EXCHANGE’ 4 pole Static Transfer Switches at a new ‘ State of the Art’ UK data centre for NYSE Euronext.

18 STS systems complete the first phase each rated at 1,600Amps, the whole package having been constructed to meet stringent customer requirements and specifications, including ASTA 80kA fault rating certification and form 4.7 segregation/separation. These are the first STS systems believed to meet such stringent specifications as a composite system.  The custom IP31 STS enclosure is designed to accommodate easy termination of multiple large single core feeder cables and to form a compatible part of a matching 96 way intelligent PDU suite supplied by Prism Power. The STS input section includes dual mains inputs with manual wrap around bypass Mccb’s in the lower section operationally interlocked by ‘castell’ keys . Connection of the STS to the PDU suite is made via a solid internal bus bar connection.  The STS units having been designed to provide future flexibility by facilitating either ‘right or left’ handed connection to the PDU’s via a separate transition section.
The full functionality and status of the STS and PDU intelligent output ways are fully monitored by the customers SCADA system using integrated Modbus interfaces.

EXCHANGE is provided in 4 pole configuration and achieves an automatic transfer from the preferred supply source to the alternate supply typically within 4msec’s (1/4 cycle).  Both input supplies being derived from the output of rotary UPS Systems.  Other features of EXCHANGE include delayed ‘retransfer’ back to the preferred supply source in the event of a  transfer being initiated.

In addition to the bespoke systems. 4 off 160A 4 pole EXCHANGE systems in accordance with their standard specification have been supplied to enhance security of supplies to other critical equipment.

Full ModBus remote monitoring of each system is provided via individual STS synoptic graphics displayed on SCADA screens located within the overall facilities control/command centre.

SIEL commission the UK’s largest roof mount solar Installation on time and within budget

SIEL Energy Systems has commissioned and connected to the grid,  the UK’s largest roof mounted solar installation on time and within budget. Sited at the new NYSE data centre in Basildon the 600kWp system was formally switched on by the Member of Parliament for Basildon & Billericay Mr John Baron and NYSE Euronext’s Group Executive Vice President and head of global derivatives, Garry Jones.

The complete system is configured with 6 SIEL SOLEIL 100kWp Inverters, which have a 25 year warranty, and a total array of 2,610 high output Multicrystalline PV modules having an overall installed surface area of 4,2892M. It has been installed with a comprehensive monitoring facility based on SIEL’s own TGS2 monitoring platform and provides constant surveillance of all the operational aspects of the Inverters and PV arrays via intelligent string connection units both on an individual and overall basis including instantaneous, monthly and cumulative generation levels.

Wayne Harris from SIEL Energy Systems commented ‘Since commissioning the system the overall performance has exceeded every ones expectations and is generating on average an output 38% higher than initially predicted’.

On 22nd February 2011 SIEL UPS Systems changed its name to ‘SIEL Energy Systems Ltd’, A name that represents a strategically important evolution for the Company in the ‘Renewable Energy’ sector for both Photovoltaic (PV) and Wind Turbine converters, a market in which we are becoming increasingly active within the UK and one in which our parent Company ‘SIEL SpA’ has become highly established in recent years within mainland Europe under the ‘SIAC’ brand name.

Our traditional core business activities for the supply, installation and maintenance of ‘Power Protection’ systems including UPS, Static Transfer Switches, Central Power Systems and other products/services will continue and be further enhanced in the future and our customers will continue to receive the highest levels of professional service and competitive solutions they have come to expect and become accustomed to since our incorporation in 1991.
