Rethinking Safety. QFire AC\/DC.<\/h2>\n\n\n\n

One Trigger. Coordinated Shutdown of PV Strings and AC Circuits.<\/strong><\/h3>\n\n\n\n

PV systems, battery storage and backup power supplies are becoming increasingly interconnected. While this makes energy systems more flexible, it also creates new challenges for electrical safety. With QFire AC\/DC<\/strong>, we are taking our proven QFire concept to the next level.<\/p>\n\n\n\n

The new system combines DC-side PV string shutdown with the coordinated isolation of designated AC circuits from grid and backup power supplies. When triggered by an external emergency stop or a suitable higher-level control signal, the control box coordinates the operation of the system components.<\/p>\n\n\n\n

What Makes It Different:<\/strong><\/p>\n\n\n\n

One System. Engineered Down to the Last Box.<\/strong><\/p>\n\n\n\n

QFire AC\/DC \u2013 Ready for Deployment. Built for What Comes Next.<\/strong><\/p>\n\n\n\n

QFire AC\/DC is already available with a 63 A ATS box. Additional ATS boxes for higher rated currents are in preparation.<\/p>\n\n\n\n

At Sustainable Solutions D\u00fcsseldorf 2026, we will present our new shutdown concept and demonstrate how PV strings and designated grid and backup power circuits can be isolated in a coordinated manner.<\/strong><\/p>\n\n\n\n

Innovation Isn’t a Coincidence. It’s How We Work.<\/h2>\n\n\n\n

Since 2010, we’ve been doing more than building boxes. We’ve been developing solutions.<\/strong><\/p>\n\n\n\n

Sometimes it starts with a specific customer requirement. Sometimes with a technical challenge that doesn’t yet have a suitable solution.<\/p>\n\n\n\n

The result? Products designed not just to work on paper, but to meet the demands of real-world installations.<\/p>\n\n\n\n

We’re not a large corporation with endless departments. Our development, project planning and manufacturing teams work closely together. That means shorter communication channels, easier coordination and faster progress from idea to solution.<\/p>\n\n\n\n

Developed and Manufactured in Germany. Personal Contacts. Smart Engineering.<\/strong><\/p>\n\n\n\n

And yes \u2013 more often than not, there’s a box at the end of it.<\/p>\n<\/div>\n\n\n\n
