Grid connection
The grid connection of the solar inverter
must have 5 wires (L1, L2, L3, PE, N). Cable
cross-sections of 5 x 4 mm2 are recommen-
ded.
The solar inverter is connected to the
supply grid via the circuit board terminals
inside the unit.
!
As line safety element in the grid feed-in
direction, we recommend a 3 x 25 A auto-
matic cut-out. No consumption units must
be connected to the feed line from the
solar inverter to the automatic cut-out.
The solar inverter only feeds in via termi-
nal L1.
If several solar inverters are operated in
parallel, the feed-in phase L1 of the unit
must be evenly distributed over grid
phases L1, L2 and L3 (see figure below).
