Field-terminable AC connectors with Plug & Play Product innovation

With our new AC connectors, PV inverters can be connected safely and reliably to the AC grid. The three-phase connector solution with PUSH IN connection technology has been optimized for cable cross-sections of up to 16 mm², which significantly reduces energy losses. Due to the robust design and the choice of UV-resistant materials, the connector can also be used under adverse environmental conditions such as vibrations and strong sunlight.

Plug in. Twist. Power.

The easiest way to wire up solar panels

Simply insert the stripped photovoltaic conductor - you don’t need a wire end ferrule.

As soon as you hear a “click”, the parts have safely made contact.

Then turn the screw cover cap a few times to tighten it. Done!
