Ambient temperature

The solar inverter can be operated in an ambient temperature between -25 °C to +70 °C.
The following diagram illustrates how the power supplied by the solar inverter is reduced automa-
tically in accordance with ambient temperature.
The device should be installed in a well-ventilated, cool and dry location.

Grid connection

The grid (AC output) is connected over a Wieland RST25i3S AC connector. You can fi nd the cor-
rect allocation on the screw-type terminal connection of the connector. The solar inverter must be
connected to the grid over a three-core line (L, N, PE). The connected AC line must be switched
potential-free before the disconnection or the insertion of the AC connector.
The connection to the Wieland AC connector must be made with a fl exible line and a conductor
cross section of min. 2.5 mm² to max. 4.0 mm².
An automatic circuit breaker is to be provided in the line L upstream of every device, with a nominal
current of 25 A and tripping characteristic type B. In addition, attention is to be paid to the selectivity
of the fuse unit attached upstream of the automatic circuit breaker.
The solar inverter must be grounded via the AC connector's PE conductor. To do this, connect the
PE conductor to the designated terminal. If you wish to integrate more than one inverter into the
installation, please proceed as illustrated in the drawings in the appendix.
Please note the cable length and the cable cross-section, due to the risk of undesirable temperature
rise and power losses.
The AC connector is protected from unintentional disconnection by a clip mechanism which can be
released with a screwdriver.
