QFire Configurator, Firefighter Switches and Smart DC Combiners
June 23–25, 2026 | Hall B4 | Booth B4.476
Firefighter switches, intelligent DC combiners, AC/DC connection technology and, for the first time, the new QFire Configurator: At Intersolar 2026, we are not just showcasing products – we are presenting solutions for real-world projects.
The Box Makers Are Coming to Munich
– bringing a new digital planning tool for firefighter switches, intelligent string fault detection and complete AC/DC connection technology manufactured in Germany.
What to Expect at Our Booth
⚡ New: QFire Configurator
Plan firefighter switch systems in just a few minutes – including live preview and automatic bill of materials generation.
🚒 QFire Firefighter Switch
Galvanic PV string isolation according to IEC 60947-3 for enhanced PV system safety.
🧠 Super Multi Box
Intelligent fault detection to ensure that a single string fault does not stop the entire PV system.
🔌 AC/DC Connection Technology
Generator junction boxes, DC combiners, AC distribution boxes and surge protection solutions from a single source.
Meet SQAY – the new QFire Configurator!
With the new QFire Configurator, planners and installers can create a project-specific preliminary design within minutes, including a live system preview and an automatically generated bill of materials.

✓ Configuration based on inverter structure, MPPTs or string quantity
✓ Optional selection of surge protection devices, fuses, emergency stop devices and status indicators
✓ Suitable for multi-roof and complex PV installations
✓ Live system preview with automatically generated bill of materials
✓ Flexible configuration using the QFire modular platform
✓ Direct project enquiry and quotation from Q3 ENERGIE
QFire Firefighter Switch
QFire provides galvanic PV string isolation in accordance with IEC 60947-3 and enables safe PV generator shutdown.
Highlights:
• Up to 24 strings per switch box
• Up to 1,500 V DC and 20 A per string
• Plug & Play installation
• Web app integration
Intelligent String Fault Detection Instead of Complete Plant Shutdown
With the Super Multi Box, Q3 ENERGIE presents a new generation of intelligent DC combiner technology.
In the event of a fault, the entire PV system no longer has to shut down. Faults can be detected precisely and individual strings can be isolated while the remaining system continues operating.
Highlights:
• String fault detection
• Individual string monitoring
• Ideal for central inverter systems
• Perfect for Agri-PV and utility-scale solar parks
Complete AC/DC Connection Technology
From PV string cabling to AC distribution systems, Q3 ENERGIE develops and manufactures project-specific connection and protection technology in Germany.
Highlights:
• Generator junction boxes
• DC combiners
• AC distribution boxes
• Surge protection solutions
• Grid and substation technology
