What happens when NEC 690.8A1 yields a short circuit current greater than the inverters maximum DC current input?
A. PV Powered inverters have internal static overcurrent protection ranging from 40 amps to 60 amps, depending on the inverter model. During operation the inverters will internally limit the DC current limit to their “Maximum DC operating current.”PV Powered limits the amount of current through its control software. For example, if the Imp (current at maximum power) is higher than the continuous 17 amp rating of the 2.8kW inverter, we will limit the input, and sacrifice available power. Q.
