AC Circuit Breaker
An independent two-pole circuit breaker is installed on the output side of the
inverter to ensure safe disconnection from the grid. The recommended
specifications are as follows:
Inverter Model
Specification
SG2K-S / SG2K5-S
15 A
SG3K-S / SG3K-D
20 A
SG5K-D
32 A
SG8K-D
50 A
Multiple inverters cannot share one circuit breaker.
Never connect a load between the inverter and the circuit breaker.
Residual Current Device
With an integrated universal current-sensitive residual current monitoring unit
inside, the inverter will disconnect immediately from the mains power once a
fault current with a value exceeding the limit has been detected.
If an external residual current device (RCD) is strictly required, install a residual
current device (type A) which trigs at a residual current of 30 mA or higher.
5.5.2 Assembling the AC Connector
