Control the output of photovoltaic systems flexibly and according to demand.
Due to an increase in the number of decentralised energy generators, such as photovoltaic systems, our power supply is changing. Many system owners do not use all of their self-generated solar power at source, but instead feed some of it into the public grid. Since storing electrical energy requires considerable effort, electricity retailers benefit from additional power sources – in particular during consumption peaks. The additional energy helps to keep the public grid constant and to ensure a stable power supply. However, at times when less electricity is required, the feeding of solar power into the public grid can overload individual sections of a distribution or transmission network, particularly in regions where there are a large number of systems. In this case, electricity retailers are legally obligated to reduce the feed-in or temporarily disconnect individual generators from the grid entirely. Fronius offers a range of options that system operators and energy suppliers can use to control the output of photovoltaic systems flexibly and according to demand.
