BayWa r.e. and Ampt have deployed a mix of wind and photo voltaic era along with battery storage inside the microgrid on the Fraunhofer Institute for Chemical Expertise (ICT) campus in Pfinztal, Germany.
BayWa r.e. put in three rooftop arrays and one ground-mounted system with a complete capability of 690 kWp to increase onsite power utilization. The methods are related to the ability grid with out their very own inverters, however as a substitute by way of an current 2 MW wind turbine. A ten MWh movement BESS is a part of the system as nicely.
Leveraging Ampt String Optimizers, every of the completely different applied sciences was built-in by way of a shared DC bus, says the corporate, including that this manner, era variability throughout the PV methods could be managed and the completely different methods united at a excessive and stuck voltage.
Ampt String Optimizers are DC/DC converters that carry out most energy level monitoring (MPPT) and get well power losses as a consequence of voltage and expertise variations, in response to BayWa r.e. Via particular person string MPPT, Ampt optimizers mitigate the power losses brought on by shade from surrounding buildings on the Fraunhofer ICT campus. The optimizers are programmable and supply string-level knowledge, enhancing visibility of the system features in addition to operation and upkeep capabilities.
“We’re delighted to deliver this milestone mission to life. Ampt’s expertise simplified a technically very advanced mission,” says BayWa r.e.’s Andrea Grotzke. “The best way now we have added photo voltaic to the prevailing wind power and battery storage system is exclusive, and in efficiently finishing this mission we have been capable of additional enhance our personal experience and capabilities. We’re happy with the results of this revolutionary energy resolution symbiosis and our capability to fulfill our buyer’s particular person necessities.”
