The safety of a PV system depends, among other things, on the design of the overall system. Modern string inverters with integrated features enable a slim system design. This avoids potential sources of error, for example through additional cabling effort when installing module electronics. In a webinar "Analyzing PV system safety and the promise of optimizers" in June 2022, Dr. Heribert Schmidt from the Fraunhofer Institute for Solar Energy Systems ISE and SMA expert Hannes Knopf discussed the influence of different system designs on the safety of PV systems. Afterwards we received so many exciting questions on the topic, which we would like to share with you. Our colleague Hannes Knopf answered the most frequently asked questions here.
Optimize energy yields in PV systems intelligently, but safely. When it comes to additional module electronics versus lean system design with modern inverter technology, Hannes Knopf is in his element. The expert in modern string inverter features knows why module optimizers are a safety risk. He explains how operators and installers can benefit from greater efficiency and safety over the entire system life with the integrated SMA ShadeFix software.
