NOTE
When Solar Inverters from different series are networked the bit rate in all units
must be identical. The rate can be set via the Solar Inverter display or the Sun-
ways Browser.

Up to 99 NT, PT and AT series units can be networked via a CAN bus. The fol-
lowing table shows the recommended cable cross-sections depending on the
bus length and the number of nodes:
In cases where the values specified in the table cannot be adhered to, a CAN
bridge for boosting the signal must be installed, through which the length of
the CAN bus can be extended by up to 500 m. The requirement to install a CAN
bridge is therefore determined by the bus length, the number of nodes and the
cable cross-sections.
The CAN bridge is available from Sunways. For further information please con-
tact the Technical Hotline.
The CAN bridge subdivides the bus into two physically independent segments.
The maximum cable length of each segment is determined by the set bit rate.
