Customised Solutions for Photovoltaics – F7 Series, Protection and Control

At Telergon, we develop solutions adapted to the real needs of solar installations. Our F7 series, Multi-string DC switches for photovoltaics, is designed to offer customised photovoltaic panels that guarantee protection, control and efficiency in self-consumption systems, industrial installations or large solar plants.

With a wide range of configurations available, the F7 series allows complete, fast and safe integration into any PV environment.

Photovoltaic Panel – Protection and Customised Sectioning

The photovoltaic panels of the F7 series are designed for maximum safety and adaptability in the field:

• Grouping of strings or independent sectioning, according to the needs of the system.

• Protection by means of fuses and surge arresters, ensuring safety in the event of faults or adverse weather conditions.

• Customisable inputs with cable glands or MC4 connectors, adapted to the type of installation.

• IP65 enclosures, dust and low pressure water resistant, ideal for outdoor environments.

It’s a modular and configurable solution, ideal for self-consumption, industrial plants and large solar installations.

Enclosed Solutions – Compacts, Fasts and Efficients

Designed for direct field integration, our F7 series enclosed solutions stand out for their simplicity of installation:

• IP66 protection, optimal for environments with high environmental exposure.

• Easy connection thanks to the use of pre-installed MC4 connectors on request..

• Plug & play design that reduces the time of installation and the mistakes during the process.

Ideal for photovoltaic installations where start-up efficiency is key.

Shunt Trip Coil – Safe and Manual Control of the Switch

The shunt trip coil option enables a higher level of safety and operability:

• Automatic switch opening via trip signal through a shunt trip coil.

• Manual operation capability.

• Simultaneous disconnection of up to 5 strings – fast and safe in the event of faults.

• Manual re-closing for local reset after intervention.

• Switch status signal – ideal for remote monitoring and diagnostics.

Ensures full system control even in emergency or maintenance situations.

Motorised Option – Intelligent Remote Operation

For installations requiring advanced automation, the F7 series is available in a motorised version:

• Remote operation of up to 5 strings simultaneously from centralised control systems.

• Automatic disconnection in the event of AC power loss (230 V).

• Integrated thermal protection with disconnection triggered at temperatures above 70 °C.

This option enables integration of the F7 series into energy management and SCADA systems, enhancing operational efficiency and remote control.

AC/DC Switch – Simultaneous AC and DC Disconnection

A compact and safe solution for hybrid installations, the F7 series AC/DC switch enables combined disconnection of both circuits in a single device:

• Simultaneous disconnection of 1 to 3 strings on the DC side.

• Single-phase configuration:

  • 2 poles, 230 V AC, 40 A (AC-21A)

• Three-phase configuration:

  • 4 poles V AC, 32 A (AC-21A)

Ideal for compact solutions where a single disconnection point is required for both power systems.
