6 Parameters and Error Messages
6.1 Configurable Parameters
Two parameters are important for the grounding of the PV plant. You can configure these parameters
in the inverter via a communication device or a PC with the appropriate software.
• Parameter "Module grounding prescribed?" (DATA II+) or "Md.GndMdt" (DATA I)
• Parameter "Prescribed grounding type" (DATA II+) or "Md.GndModReq" (DATA I)
6.1.1 Parameter "Module grounding prescribed?" or "GndMdt"
The grounding module in the inverter is configured via the parameter "Module grounding
prescribed?" or "Md.GndMdt". Make sure you comply with the requirements of the module
manufacturer as well as the regulations applicable at the installation location of the PV plant.
There are two configuration possibilities:
Parameter names according to the type of communication
Depending on the communication type (Bluetooth or RS485), the inverter uses a different
communication protocol and the parameters are displayed differently.
• Communication via Bluetooth and Sunny Explorer: DATA II+
• Communication via RS485: DATA I
Value
(DATA II+ / DATA I)
Explanation Default Value
(DATA II+ / DATA I)
No The grounding is not prescribed by normative
regulation or the manufacturer. Despite this
configuration, you will be able to ground the PV
plant.
In case of a grounding error, the inverter will
continue to feed into the grid. For information
purposes, the inverter displays a warning with the
event number "35". No
Yes Grounding is prescribed by normative regulation
or the module manufacturer. The inverter can only
be operated with an SMA Plug-in Grounding set.
In case of a grounding error, the inverter will not
continue to feed into the grid and interrupts
operation. The inverter displays a warning with the
event number "35" in case of an insulation error.
