New generator connection boxes for photovoltaic systems

The new photovoltaic sets for multi-string inverters reliably protect photovoltaic systems with two or three  independent strings of up to 1000 V DC against surge voltages.


Modern inverters regulate the maximum energy yield via several Maximum Powerpoint Trackers, also known as MPP trackers.

The trackers optimally adjust the electrical parameters of the entire photovoltaic system to the current radiation conditions of the individual strings. This enables the maximum output to be achieved from the modules.

Protection for each individual MPP tracker

With the new generator connection boxes for multi-string photovoltaic systems you can protect each individual MPP tracker of an inverter against damage caused by surge voltages. In this way, you can automatically ensure continuous energy generation.

The photovoltaic sets are fully prewired in easy-to-install IP65 housings, and are equipped with photovoltaic plug-in connectors. Versions are available for inverters with two or three MPP trackers.
