Table 6.2 Cable specifications on the PV side
Recommendation cable specifications
NOTE:
1. For a single WIT Inverter, connect the ground cable of the inverter. For a system with multiple WIT Inverters
connected in parallel, connect the ground cables of all inverters and the metal racks of the PV modules to the same
area to ensure equipotential bonding. Before connecting the PV cables, ensure that the ground cables on the PV
side are properly connected.
2. Use male and female connectors in pair. Ensure the correct polarity before connecting the PV string to the
inverter.
3.The total current of all strings cannot exceed the WIT Inverter's maximum input current;
4. Do not touch the solar panels in operation;
5. The wires should be tinned and are not frayed or cracked.
6.4 Connection on the Battery Side
● Before connecting cables, ensure that the DC switches of the WIT Inverter are
OFF, and turn off the breakers on the AC side and the battery side. Otherwise, the
high voltages of the WIT Inverter may cause 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.
● Please do not place inflammable and explosive materials around the WIT
Inverter.
● If the cable is thick, do not shake the cable after fastening it. Ensure that all
cables are securely connected before powering on the WIT Inverter. Loose
connection may cause overheating that will damage the device.
●The battery terminals are protected by a plate. Upon completion of wiring on the
battery side, reinstall the protective plate to prevent accidental touch.

Preparation:
1. Check that the battery terminals of the WIT Inverter are intact;
