Check criterion
The battery current sensor can be loaded
with the maximum DC current (see technical
data of the battery current sensor).
Check criterion
All enclosure openings are sealed with M25
cable glands or filler-plugs.
The core cross-section of the cable must be
9 mm... 18 mm for an M25 cable gland.
All contact areas are free of insulation.
All levers on the terminals are in the
downward position.
All cables are securely clamped.
The stand-alone grid or the Multicluster Box
is connected to the AC1 Loads/
SunnyBoys terminals.
The external energy source is connected to
the AC2 Gen/Grid terminal.
For a TN system, the neutral conductor is
connected to the AC2 Gen/Grid N
terminal.
For a TT system, the neutral conductor is
connected to the AC2 Gen/Grid N
terminal.
The allocation of the off-grid inverters to the
line conductors of the stand-alone grid or the
Multicluster Box results in a right-hand
rotating magnetic field. Master must be
assigned to L1, slave 1 must be assigned to
L2, slave 2 must be assigned to L3.
