5.6 Suitable breaker
1.
The rated voltage shall ≥60V DC. Do
NOT
use AC breaker.
2.
The type of breaker shall be type C (recommended) or type D.
3.
The rated current shall match with system design:
shall consider the DC current on inverter side.

current of breaker shall be 125A or smaller.
4.
The Icu required:
the short circuit current for calculation of each module is 2500A. for instance:
Icu of breaker
1~4 modules
Must ≥10kA
5~8 modules
Must ≥20kA
5.7 Power on
Double check all the power cable and communication cable.
