3.3.3.1. Working mode
These inverters are factory configured with three MPPTs which
are electrically divided into separate PV input zones: PV Input-1,
PV Input-2, and PV Input-3. Each 5-string PV input zone
operates as a separate and independent MPP Tracker.
Independent mode can be very useful for sites with partial
shading of the array or with arrays consisting of different tilt or
