API field
MPPT minimum
What happens when the array voltage falls below the MPPT window
What it is
Selects what the model does when the array's maximum-power voltage falls below the inverter's lowest tracking voltage.
Typical values and how to get it
Chosen on the Model tab.
Values
Hold the MPPT minimum, fitted voltage trim = displaced (default): the array operates at the MPPT minimum, with the current read on the array curve at the floor voltage plus the cable drop, less a small fitted voltage trim (MPPT minimum step on the Model tab); the inverter stops when the open-circuit voltage is below the floor · Hold the MPPT minimum, curve current = clamp: the array operates at the MPPT minimum, with the current the curve gives at the floor voltage plus the cable drop; nothing is delivered when the open-circuit voltage is below the floor
