MPPT window minimum

Lowest voltage at which the inverter tracks the maximum power

Unit V

What it is

The lowest DC voltage at which the inverter tracks the array's maximum-power point, in volts. When the array's maximum-power voltage falls below it, usually on hot days, the inverter operates the array at this voltage instead and loses some power.

Typical values and how to get it

The inverter datasheet value. An OND file carries it too. If not given: 0 V: no lower edge to the MPPT window.
