Appropriate Usage
If you use special cell technologies in your PV generator (e.g. thin-film PV modules and backcontact
¡V modules], it may be necessary to ground the PV generator, either positively or negatively. With this in mind SMA Solar Technology has developed two grounding sets with which the positive or negative grounding of the PV generator, as recommended by the module manufacturer, can be performed already within the inverter. This device-internal grounding provides safe long-term operation and opfimum EMC properties while minimizing the installation costs.
The grounding set includes a 1 A fuse as protection against the danger of fire and a circuit adjusting the inverter's isolation monitoring to the grounding set. The grounding set directly connects the pole to be grounded (plus or minus) of the PV modules and the inverter's PE connection via the fuse. This circuit has been designed for Germany and is suitable for many other countries as well. Before installation, check if the installation country allows to connect a pole to ground.
The posifive grounding set (ESHV-P-NR) is used, for example, for certain modules with back contact cells. The negative grounding set (ESHV-N-NR) is used, for example, for thin-film modules. Your module manufacturer can provide you with information on the necessity and type of grounding of your PV system.
