The Positive Grounding Kit from Critical Power Supplies.

It can be necessary when using thin-layer modules and back-to-back cells to ground the positive or negative connection of the PV generator. With the Grounding Set we offer you the optimal solution for this.

The Grounding Set offers the following advantages:

- The set is available for both the positive and also negative grounding.
- Due to the internal grounding, changing the external generator cabling is not required which saves time.
- The grounding is fused by an internal thermal fuse and therefore provides additional safety (fire protection).
- With the Grounding Set they can be seamlessly integrated into the inverter. Thus the isolation monitoring remains completely preserved. This important safety feature of SMA devices can identify possible insulation failures within the generator.

Your module manufacturer can provide you with up-to-date information on the necessity and type of grounding.
