BayWa r.e. and Ampt have deployed a combination of wind and solar generation together with battery storage within the microgrid at the Fraunhofer Institute for Chemical Technology (ICT) campus in Pfinztal, Germany.
BayWa r.e. installed three rooftop arrays and one ground-mounted system with a total capacity of 690 kWp to expand onsite energy utilization. The systems are connected to the power grid without their own inverters, but instead through an existing 2 MW wind turbine. A 10 MWh flow BESS is part of the system as well.
Leveraging Ampt String Optimizers, each of the different technologies was integrated through a shared DC bus, says the company, adding that this way, generation variability across the PV systems can be managed and the different systems united at a high and fixed voltage.
Ampt String Optimizers are DC/DC converters that perform maximum power point tracking (MPPT) and recover energy losses due to voltage and technology differences, according to BayWa r.e. Through individual string MPPT, Ampt optimizers mitigate the energy losses caused by shade from surrounding buildings on the Fraunhofer ICT campus. The optimizers are programmable and provide string-level data, enhancing visibility of the system functions as well as operation and maintenance capabilities.
“We are delighted to bring this milestone project to life. Ampt’s technology simplified a technically very complex project,” says BayWa r.e.’s Andrea Grotzke. “The way we have added solar to the existing wind energy and battery storage system is unique, and in successfully completing this project we were able to further improve our own expertise and capabilities. We are pleased with the result of this innovative power solution symbiosis and our ability to meet our customer’s individual requirements.”

I met a guy earlier today who told me that wind and solar are controversial, and that some people say that the mining and manufacturing of wind turbines requires more fossil fuels that the turbines themselves produce.
I told him that I’m aware of such people; they’re called “professional liars.”
I explained the concept of EROI, energy return on investment, and surprised him by saying that the EROI of wind is somewhere between 18 and 30, meaning that each wind turbine you see as you drive along the freeway will generate at least 18 times as much energy as was required in its mining, fabrication, installation, maintenance, and decommissioning–all the way up to 30 times that amount.
The generation of disinformation of renewables has become a cottage industry. People are paid to make up and publish complete bullshit, so as to discredit the burgeoning clean energy industry, and keep Big Oil in place.
As bad as things are in the United States, they could always get worse.
Trump could succeed in his quest to be a dictator, Christianity could be taught in schools, and unvaccinated adults and their kids could trigger another epidemic.
In terms of our reputation on the world stage, however, things really can’t get must worse; the countries around the globe already regard us with a mixture of hate and derision.
Yet regardless of what the future holds, there will always be idiots who that believe that Trump is our savior, like the author of the meme above.
Good to see John Eastman disbarred in California; it’s a small measure of justice.
Criminal prosecution in the future?
