Inverter saturation, commonly referred to as “clipping”, occurs when the DC power from the PV array exceeds the maximum input level for the inverter. In response to this condition, the inverter typically adjusts DC voltage to reduce the DC power. This is done by increasing voltage above the MPP voltage, thus reducing DC current.
PV system modeling is primarily done on hourly timescales and so cannot capture subhourly effects, including inverter saturation. Inverter saturation occurs when the potential dc power, P dc , produced by the collectors is greater than the inverter capacity, and some of the PV power is lost or “clipped.”
A: On days of Solar Saturation the network voltage is a direct result of the inverters trying to put power back into the grid; adjusting the voltage at the supply transformer will have no effect as the voltage in the area is dictated by the inverters competing against each other.
Having inverters cutting out on days of Solar Saturation is not a fault, rather it is normal operation of the solar generating system. The above charts highlight a real-world example of solar saturation. Whilst this does show an impact to the total kWh generated (34 kWh vs 39 kWh) this is equivalent to only a few dollars loss in export to the grid.
Our solar power systems and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
