Wiring inverters - safely, quickly, and easily with a lever

The roofs of many homes are already adorned with photovoltaic systems. But to ensure that the electricity generated from solar power also finds its way to your sockets, you need an inverter. To make the connection as safe, quick, and easy as possible for the installer, Fronius uses the lever connection technology from WAGO for its GEN24 Plus inverter generation – currently making it one of a kind on the solar inverter market.

The German Design Award, Intersolar Award, Red Dot Design Award, Plus X Award - these are just some of the accolades the inverter manufacturer Fronius has received for its GEN24 Plus hybrid inverter. If there were a prize for the easiest inverter installation, this would probably also be on display in the Fronius trophy cabinet – thanks in part to the combination of push-in spring connection and the globally self-explanatory WAGO lever technology, which makes both ferrules and tools entirely superfluous when installing the GEN24 Plus. A feature that is presently unique on the global inverter market.

WAGO PCB Connectors with Lever:

Intuitive and fast: tool-free wiring thanks to lever technology
Tight and safe: stable fit of the PCB connector
Convenient and easy: wiring by hand in hard-to-reach places

Unmatched convenience coupled with unbeatable quality

This innovative connection technology is made possible by WAGO PCB plug connectors, specifically the WAGO Multi Connection System MCS MAXI 6 from the 831 series. “This tool-free wiring of all types of conductor by means of a lever is intuitively usable anywhere in the world, saves the installer a great deal of time on site, and gives them peace of mind,” says Markus Rieder, Global Head of Sales for the Business Unit Solar Energy at Fronius International. This not only simplifies the installation of this durable hybrid inverter for DC and AC connections, but also its servicing requirements. In addition to lever operation, these high-quality WAGO PCB plug connectors with levers withstand a wide variety of environmental conditions in the field: from the desert to 4000 meters above sea level, wherever the Fronius inverters are installed.

But what sounds simple now is the result of almost four years of joint development work. In addition to the 831 series plug connectors, the WAGO solution also includes further modifications – such as factory coding of the terminal points to prevent mis-mating, and factory printing to further increase the convenience of the field connection.
