5.6 Connecting the other station components
The correct electrical installation of the following components is in the hands of the sta-
tion outfitter. SolarMax Produktions GmbH instructions in this regard are limited:
AC circuit breaker
To protect the inverter and to permit its complete AC-side disconnection, an AC power
switch must be connected to the AC connection of the inverter.
Specification AC circuit breaker:
■
■
Maximum current: 800 A
■
■
Maximum voltage: 280 V (SM330TS-SV) / 320 V (SM360TS-SV)
■
■
Thermal and magnetic overcurrent release
Alternatively, an NH switch disconnector fuse with 800A NH fuses may also be used.
Medium voltage transformer
Standard values for dimensioning and typical characteristics can be found in 3.4.3
“Medium-voltage transformer”.
Autonomous power supply transformer
The star point on the secondary side (400 V) must be earthed. On the primary side (280 V
/ 320 V), no star point is necessary. The autonomous power supply transformer must be
fused on the primary and secondary sides.
