However there are limits in power, voltage and current. When attaining one of these limits, the inverter will clip the operating point on the intersection of the I/V curve and this limit. The power difference between the MPP of the arrays' I/V curve and the effective power of this operating point on the limit curves is accounted as inverter loss:
This is only possible when you define a low voltage for your array, i.e. few PV modules in series. Therefore in many cases when the operating (or nominal) current of the array is above the acceptable current for the inverter input, you will not see any Current loss during operation, but only Power overload.
The inverter input electronics assumes the function of choosing the operating point on the I/V curve of the PV array. In normal conditions it will choose the maximum power point (MPPT tracking). However there are limits in power, voltage and current.
The power difference between the MPP of the arrays' I/V curve and the effective power of this operating point on the limit curves is accounted as inverter loss: The current limit condition may be specified: Imax = Pnom (DC) / VminPNom, where PnomDC = PnomAC / Efficiency.
In normal conditions it will choose the maximum power point (MPPT tracking). However there are limits in power, voltage and current. When attaining one of these limits, the inverter will clip the operating point on the intersection of the I/V curve and this limit.
The increase in bus voltage is used as the control signal of the PV output current to reduce the photovoltaic output current, such that the PV output power is reduced from 3000 W to the inverter power limit value of 1500 W, which meets the requirements of the inverter output power limit.
