1) The rated voltage shall ≥60V DC. Do NOT use AC breaker.
2) The rated current shall match with system design:
shall consider:
 the maximum DC current on inverter side.
 the number of power cable: for instance, if only one pair of 4awg cable,
the rated current of breaker shall be 125A or smaller.
3) If using breaker, the type shall be type C (recommended) or type D.
The Icu required:
the maximum 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
