Hi Ryan, could you explain? why Lower capacity of inverter has max fault current contribution (1 cycle rms) is more than high capacity of inverter of max fault current contribution (1 cycle rms) For example a. CPS inverter model name CPS SCA 36 ktl-DO/US-480 has fault current contribution (1 cycle rms) is 73.2 A (1.68 PU),, while b. CPS inverter model name CPS SCA 60 ktl-DO/US-480 has maximum fault current contribution (1 cycle rms) is 64.1 A (1.6/0.88PU).
This is an excellent question. We do not have enough information on those inverter models to give you a thorough answer. We recommend contacting CPS's engineering department, who should be able to share more details.
