SmartConnect
Operating manual

Brief description

The SmartConnect performs all the basic functions of a junction box for
photovoltaic systems (PV systems) with central inverters. The
SmartConnect brings the individual strings of the solar power system
together and monitors them. It transfers the supplied current via a main
cable to the generator switch box (GKK) or directly to the central inverter.
The SmartConnect features an integrated direct current main switch (DC
disconnect).
Functions
Protection of the central inverter against overvoltages as a result of
|
switching faults and cold weather conditions.
Protection of the central inverter if strings are connected with reversed
|
polarity.
Precise forward and reverse current limitation.
|
Parallel switching of individual strings.
|
The SmartConnect enables the solar generator to be flexibly switched at 8
inputs. Up to ten strings can be connected per interface, provided the
maximum input current of 20 A per input is not exceeded.
