I was looking to compare two microinverters: IQ7Plus-72-x-US [240V] vs the IQ7A-72-x-US-& [240V] using the Inverter CEC database entries.
I set up a simulation with the same location, same panel, same system design and the IQ7A has a significant "Inverter MPPT clipping" in the Nominal DC energy (kWh) section of the Losses result section while the IQ7Plus doesn't show any losses here.
The
IQ7Plus datasheet
seems to match the Min/Max MPPT at 27/45V. The
IQ7A datasheet
says the Power Point tracking voltage range is 18V-48V but a footnote says the CEC range is 38/43V and the CEC entry does reflect that.
I presume the 38/43V range is responsible for this result? Though I don't understand why there would be such a large difference between the CEC range and the non-CEC range reported on the datasheet.
