|
Powerline interface |
As standard |
* The DC connectors supplied are dependent on the order. You can find the SMA order numbers of the DC connectors in this document ( > Spare Parts and Accessories).
** The length of the AC cable is either 1.40 m (4.6 ft) or 2.0 m (6.6 ft), depending on the order option.

Suitable |
|
Autotransformer* |
Limited suitability |
* When using autotransformers, take into account that the voltages of L1 to the grounding conductor and L2 to the grounding conductor are – in no-load operation as well as under load – within the permissible range and symmetrical. If the voltages are not symmetrical, the inverters are not damaged, but they also do not feed in. The PV system can therefore not be operated on this transformer.
