Part Load Efficiency - SAM was created by marinacmasca
When I choose on SAM the Part Load Efficiency Model for Inverters and I will type the values given by the manufacturer, which voltage is being considered by SAM? Because the Datasheet will give me the efficiencies according to the load in 3 options:
- Minimum MPP voltage
- Rated input voltage
- Maximum MPP voltage

Which one is more suitable?

Thanks :)

Hello,

You can enter those voltages in the "Operating Ranges" box, where they are listed as:

Minimum MPPT DC Voltage (Vdc)
Nominal DC voltage (Vdc)
Maximum MPPT DC voltage (Vdc)

SAM uses the MPPT voltage range to calculate inverter clipping losses.

Best regards,
Paul.
