The SMA Positive Grounding Kit ESHV-P-NR is a high-voltage positive earthing set designed for SMA transformer-based inverters, providing safe grounding for PV modules with rear-contact or thin-film cells that require positive pole earthing.

Product Description

This grounding kit connects the positive PV array pole to earth through a thermal fuse, neutralising potential differences and preventing corrosion in certain module technologies. It integrates with the inverter's insulation monitoring and offers fire protection through thermal fuse disconnection.

Key Features

Positive earthing: Grounds the positive PV array pole for module protection.
Thermal fuse protection: Automatic disconnection in case of fault or overcurrent.
Insulation monitoring compatible: Works with SMA inverter safety systems.
Simple installation: Retrofit kit for compatible SMA inverters.
Fire safety: Thermal fuse prevents arcing in fault conditions.

Technical Details
