At the ecobuild 2016 from March 8 to 10 in London, Solare Datensysteme GmbH will present a wide array of solutions to manage PV power efficiently and to optimize yields.
Solar-LogTM – Export Restriction Solution
The UK’s grid network capacity for feed-in energy produced by a solar PV installation is becoming more of a concern, with some G59/3 applications even being rejected completely by the responsible DNO. In other areas, grid saturation constraints lead to stipulated maximum reverse power limits imposed by the DNO, which is often far less than the peak theoretical limit that the Solar PV array can produce.
Historical solutions to overcome these export limitations were focused primarily on a basically electro-mechanical shut-down of the solar PV inverter bank, either in part or entirely, which is not an ideal solution, as the generation/yield of the system can potentially be severely compromised.
The Solare Datensysteme GmbH (SDS), together with its distributor Sibert Instruments Ltd (Sibert Solar), developed the “Solar-LogTM Export Restriction Solution”. The Export Restriction Solution combines the inherent power-management capabilities of Solar-LogTM control systems with a fail-safe backup unit, should the control system fail or ceases to be effective. This solution is a standardized, yet scalable framework to provide dynamic, closed-loop power management control over the inverter bank, suitable for up to 2MWp size arrays.
