Only need some of these services? No problem. We tailor our offer to your exact requirements.
Building Electrical Systems. Fully tested.
Testing the building's electrical infrastructure is a key part of DGUV V3 compliance. We inspect the entire electrical installation, from the main distribution board down to individual outlets.
Electrical Distribution Boards
Inspection of all main and sub-distribution boards for proper condition, correct fusing, and labeling.
Lighting Systems
Testing of all lighting including emergency and safety lighting per DIN EN 50172.
RCD/GFCI Protection
Functional testing of all residual current devices with trip time and trip current measurement.
Outlets & Wiring
Inspection of all fixed outlets, wiring, and connection points for proper condition.
PV System Testing. Protect your output.
Photovoltaic systems are electrical installations and fall under DGUV V3 testing requirements. We perform both initial commissioning tests and repeat inspections with calibrated Fluke instruments, combined with thermographic analysis.
I-V Curve Measurement
Current-voltage characteristic measurement of each string to detect power losses and defective modules.
Insulation Testing
Insulation resistance measurement of DC wiring and modules to detect insulation faults.
Thermography
Thermographic inspection with Fluke thermal cameras to detect hot spots, defective cells, and bypass diode failures.
Tip: We recommend combining PV testing with a thermographic inspection. That way you catch not just electrical faults but also thermal anomalies like hot spots.

Frequently Asked Questions about DGUV V3
DGUV V3 testing (formerly BGV A3) is a legally required inspection of electrical systems and appliances in businesses. It covers portable devices, fixed installations, building electrical systems (distribution boards, lighting, RCDs, emergency lighting), and photovoltaic systems. We work exclusively with calibrated Fluke instruments.
Testing intervals depend on the type of equipment and usage. Portable devices in offices are typically tested every 24 months, in workshops every 6 months. Fixed installations and building systems every 4 years. PV systems should be tested every 4 years per DIN VDE 0126-23.
DGUV V3 testing may only be performed by qualified persons (certified electricians) with appropriate qualifications, professional experience, and regular continuing education. Our inspectors are TUV-certified.
Costs depend on the number of devices and systems to be tested. We offer transparent fixed pricing per device. Contact us for a custom quote. The initial consultation is free.
Non-compliance can result in fines up to 25,000 EUR, insurance exclusion in case of accidents, and personal liability for the business owner. In the event of damage, this can be existentially threatening.
Yes, we test the entire building electrical infrastructure (distribution boards, lighting, RCDs, emergency lighting) as well as photovoltaic systems per DIN VDE 0126-23, including I-V curve measurement, insulation testing, and thermographic inspection.
We work exclusively with calibrated Fluke instruments. Fluke is the global leader in electrical test and measurement equipment, guaranteeing the highest measurement accuracy and reliability.
