System inspection

Whether a new or existing pv system:
We check the condition and
compliance with all requirements

We check for you the flawless implementation, as well as the condition of existing pv systems and ensure error-free system operation.
From the examination of the qualitative execution of the systems to the verification of compliance with all standards and safety regulations.

System Safety

Characteristic Curve Measurement PV

During the system inspection, all switching and safety devices are tested.
The insulation resistance on the DC side is measured to exclude insulation faults in cables, plugs, or modules. The earth connection or potential equalization is checked - in combination with the control of the surge protection concept, effective protection in the event of overvoltages and lightning strikes is ensured.
To prevent fire damage, a check of the terminal connections in the junction boxes is carried out.

Furthermore, we conduct a visual inspection of the mechanical construction to detect, for example, open or missing module clamps.

Standards and Guidelines

For photovoltaic systems, there are a number of special guidelines that apply in addition to the general electrical regulations. These deal with the particularities and dangers arising from the fact that high direct currents occur in PV systems. This includes, for example, the ÖVE R11-1 for the protection of emergency responders, or the ÖVE R6-2-1 and 6-2-2 which deal with lightning and surge protection.

During the system inspection, we check compliance with the guidelines.

The system inspection itself is carried out according to ÖVE EN 62446 and ÖVE E8101.

Partner Network

Together with our partners, we can easily offer special measurement methods. Here, electroluminescence or UV fluorescence tests are possible, as well as laboratory tests of modules or the analysis of power quality at specific grid nodes.

If defects occur in a system, our electrical partners are available to take care of the damage repair.
