PV sets – easy installation

Pre-assembled PV sets simplify the installation of lightning and surge protection in your photovoltaic system. All sets are supplied in IP65 housing, which is protected against dust and jet water.

PV-SET 1ST/1000DC/1MPP-SPD-SC for the single-string system

Protection of a single string with the PV-SET 1000 DC

The PV-SET 1ST/1000DC/1MPP-SPD-SC protects the single-phase inverter in your single-string system on the DC voltage side.

Easy installation

  • SUNCLIX plug-in connectors
  • Fully wired

Consider the cable length

  • For a cable length less than 10 m between the solar panel and inverter, it is sufficient to install a PV-SET 1ST/1000 DC/... directly before the inverter.
  • For longer cable lengths, it is recommended that you also install a PV-SET 1ST/1000DC/… directly at the solar panel.

Protection of the AC side

The AC side of the inverter is protected by a surge arrester.

PV-SETs for inverters with multiple MPP trackers

Protection for inverters with multiple MPP trackers

In order to get maximum performance from your PV system, you should use inverters with multiple MPP trackers.

You can provide the right protection for these inverters with the following products:

  • PV-SET 2ST/1000DC/2MPP-SPD-SC
  • PV-SET 3ST/1000DC/3MPP-SPD-SC

Protect inverters with multiple MPP trackers on the DC voltage side against lightning currents and surge voltages up to 1000 V DC.

Easy installation

  • Fully wired
  • Fast installation, thanks to SUNCLIX plug-in connectors

Consider the cable length

For cable lengths greater than 10 m between the inverter and solar panel, additional surge protection should be provided at the solar panel. For example, use the PV-SET 1ST/1000DC/1MPP-SPD-SC for this.

The AC side of the inverter is protected by a surge arrester.

PV-SET 5ST/600 DC for a maximum of five strings

Protection for solar plant, up to 5 strings  

Protection for up to five PV strings

The pre-wired PV-SET 5ST/600 DC protects up to five PV strings with a string voltage of 600 V DC against surge voltages.

  • A generator disconnect provides additional safety.
  • Usually the strings are combined before the inverter and are protected here with the PV-SET 5 ST/600 DC.
  • For cable lengths greater than 10 m between the inverter and solar panel, an additional set should be provided at the solar panel for protection against lightning currents and surge voltages. Use the PV-SET 1ST/1000DC/1MPP-SPD-SC for this.
  • The AC side of the inverter is protected by a surge arrester.

Protection of the AC and DC side of the inverter

Protection of a solar plant on the AC and DC side  

Protection of the AC and DC side of the inverter

The inverter should be protected against surge voltages on both the DC and AC voltage side.

AC and DC voltage protection combined

Using the PV-SET 1000 DC/AC, you can combine the DC voltage protection of the PV-SET 1000 DC with the AC voltage side from the outset.

Consider the cable length

If the cable between the solar panel and inverter is longer than 10 m, a PV-SET 1ST/1000DC/1MPP-SPD-SC should also be installed directly at the solar panel for this set.
