NOTE
x Depending on the grid operator, a three-phase meter or a single-phase meter
must be used.
x Some grid operators require the use of a reverse-current-capable meter.
A basic distinction is made between two different connection options of the inverter
to the mains:
x Three-phase AC grid (e.g. Germany)
x Single-phase AC grid (e.g. Italy, Spain)
CAUTION
x Observe the regional regulations for the grid connection.
NOTE
The grid connection of the inverter should always be single-phase. An AC bayonet
connector on the underside of the unit is used for the three-wire grid connection (L,
N, PE) of the inverter. Feeding is single-phase via AC terminal 2.
If several inverters are operated in parallel in a 3-phase grid, AC terminal 2 of the unit
must be distributed uniformly among the grid phases L1, L2 and L3 to avoid unequal
loading.
