Standardised grid protection for photovoltaic systems

Standardised grid protection for photovoltaic systems

Optimum NA protection for PV systems up to 300 KW / 330 KVA

Our grid and system protection (NA protection) for photovoltaic systems is specially designed for use in TNS / TT grids and fulfils the strict requirements of the VDE-AR-N 4105:2018-11 standard. This protection mechanism is ideal for PV systems with an output of up to 300 KW / 330 KVA and offers complete all-pole disconnection and an integrated tie switch.

Centralised NA protection for maximum grid and system safety

Our NA protection system guarantees the safety and efficiency of your photovoltaic system thanks to the following special features:

The mains and system protection fully complies with the VDE-AR-N 4105:2018-11 standard and therefore guarantees the highest safety and performance standards.

Flexible assembly:
The system can be mounted both on the wall and on a foundation, allowing flexible installation in different environments.

Centralised NA protection:
Integrated protection mechanism ensures comprehensive grid and system security and minimises the risk of grid faults.

Robust housing:
The glass fibre reinforced polyester housing with a high IP54 protection rating is ideal for various installation environments and offers excellent protection against external influences.

All-pole disconnection:
Our NA protection system ensures maximum safety by completely isolating all poles, which enables reliable and safe disconnection of the photovoltaic system from the grid.

Advantages of NA protection

  • Maximum security: Centralised NA protection offers comprehensive safety measures for your photovoltaic system.
  • Reliability: Meets all relevant standards and requirements to ensure safe and stable operation.
  • Versatility: Can be used flexibly in various network configurations and installation environments.
  • Robustness: The robust housing effectively protects the internal components and ensures a long service life.

Our standard-compliant grid protection for photovoltaic systems offers efficient disconnection and protection mechanisms that have been specially developed for the requirements of modern PV systems. Discover the benefits of our NA protection system and ensure the reliability and safety of your photovoltaic system.
