EFFECTIVE GROUNDING FOR PV PLANTS
As the low voltage side of the medium voltage transformer is configured in delta, the PV inverter is connected to a three wire system and PV inverter does not need to provide effective grounding.
GROUND-FAULT PHOTOVOLTAIC ANALYSIS AND
Ground-faults within PV modules, i.e. a solar cell short circuiting to grounded module frames due to deteriorating encapsulation, impact damage, or water corrosion in the PV module.
Grounding of Industrial and Commercial Photovoltaic Inverters
Effective grounding in photovoltaic (PV) systems is the creation of a low-impedance reference to ground at the AC side of the inverter--or group of inverters--that is designed to be compatible
Grounding and Methods of Earthing in PV Solar
The concept and purpose of grounding in DC systems, such as solar panels and photovoltaic arrays, are the same as in AC systems. However, the

Technical Information
If a PV system includes multiple inverters, each one must be individually connected to the main grounding busbar to ensure proper grounding. Never connect the grounding cables of

If the transformer is wye-delta configured with the wye on the grid side, the neutral terminal can be used for effective grounding as shown in Figure 3 a). In most of the cases, the grid voltages are well balanced and the distribution loads contain limited harmonic current. In that case, th...See more on solectria mersen [PDF]
