Connecting The Ac Grid To The Connection Unit - SolarEdge SE12.5K Installation Manual

Connecting the AC Grid to the Connection Unit

NOTE
Functional electrical earthing of DC-side negative or positive poles is
prohibited because the inverter has no transformer. Grounding (earth
ground) of module frames and mounting equipment of the PV array modules
is acceptable.
NOTE
SolarEdge's fixed input voltage architecture enables the parallel strings to
be of different lengths. Therefore, they do not need to have the same
number of power optimizers, as long as the length of each string is within the
permitted range.
WARNING!
Turn OFF the AC before connecting the AC terminals. If connecting
equipment grounding wire, connect it before connecting the AC Line and
Neutral wires.
NOTE
It is recommended to connect communication connections ( Setting Up
Communication on page 61) before connecting the AC, for easier access to
the communication board.
