6.1 Connecting The Ground Cables
3. For a single WIT inverter, connect a ground cable to the ground point on the chassis
shell. For a system with multiple WIT inverters connected in parallel, ensure that the
enclosures of the WIT Inverters, the metal racks of the PV modules and the batteries
are connected to the same area to achieve equipotential bonding.
2. All non-current-carrying metal parts and the enclosures of the devices of the energy
storage system should be properly grounded, including the rack and the enclosures of
the combiner box, the distribution panel, the inverter and the battery.
1. It is essential to connect the ground cable to the WIT inverter before connecting other
cables to prevent personal injury or device damage.
4. The position of the ground points of the WIT 50-100K Storage/Hybrid Inverter is
shown in Fig 6.1. You can find the ground points after removing the right cover plate.
NOTE:
3. Tighten the enclosure grounding screw to a torque of 60 kgfยทcm.
2. Protect the terminals of the ground cables against rain and do not expose the them to
open air.
1. Keep the lightning protection grounding at the greatest possible distance from the
protective grounding.
