DC GROUND
Even though the inverter operates with an ungrounded PV array, the PV system still
requires equipment grounding.

2.3.1 DC Connection
1) Working Mode
PVI 36TL inverter has two PV input sections: DC Input-1 and DC Input-2. These
two sections can work in “Parallel mode” or “Independent mode” (see Figure 2.20).
The default setting from the factory is “Parallel mode”.
In Parallel mode, the two PV input sections share one MPP Tracker; In
Independent mode, each PV input section works with independent MPP Tracker.
