Lightning and surge protection

VARITECTOR PU PV for more safety

PV systems are directly exposed to environmental influences because they are always installed in exposed locations. Therefore the probability of lightning strikes and resulting overvoltage is high. The components of unprotected PV systems are again and again considerably damaged.

VARITECTOR PU PV for more safety
  • Type I devices are available in 1,000 and 1,500 V DC versions
  • Type II devices are available in 600, 1,000, 1,200 or 1,500 V DC versions
  • Optionally with or without a remote signalling contact
  • The entire product portfolio for photovoltaic systems complies with the current photovoltaic standard EN 50539-11


PV Protect is the compact solution for optimum protection of the inverter against overvoltages The ready-to-connect boxes are available for different system voltages and can be supplied with various arrester types and MPP trackers.

  • Compact, space-saving design
  • Available in product variants suitable for different applications
  • Ready to connect solution in protection class IP67
  • Reliable and maintenance-free PUSH IN connection technology

Emergency Power Box

Emergency Power Box for Fronius Primo GEN24 Plus

The inverter manufacturer Fronius therefore offers the option of supplying consumers in the event of a power cut in its Primo GEN24 Plus product range. Weidmüller has developed the appropriate emergency power box to connect the necessary loads quickly and safely if required.
