6.1 Connecting the Ground Cables
1. It is essential to connect the ground cable to the WIT inverter before connecting other cables to
prevent personal injury or device damage.
2. All non-current-carrying metal parts and the enclosures of the devices of the energy storage
system, including the rack and the enclosures of the combiner box, the distribution panel, the
inverter and the battery should be properly grounded.
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.
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.
Fig 6.1 Ground points
NOTE:
1. Keep the lightning protection grounding at the greatest possible distance from the protective grounding.
2. Protect the terminals of the ground cables against rain and do not expose the them to open air.
3. Tighten the screws to a torque of 60 kgf·cm.
6.2 Connection on the AC Side
● Before connecting cables, ensure that the DC switches on the WIT Inverter are
OFF. Turn off the switches and breakers on the AC side and the battery side.
Otherwise, the high voltages of the WIT Inverter may result in electric shocks.
● Only qualified and trained electrical technicians are allowed to perform operations.
Technicians must observe instructions in this manual and local regulations.
● High voltages may cause electric shocks and serious injury. Please do not touch
the inverter in operation.
● Do not place inflammable and explosive materials around the WIT Inverter.
