1Cable Wiring Procedure
1.1 LG Generation II and SH5K
The LG Generation II battery communicates with the Sungrow SH5K V11 inverter via
an Ethernet cable. Prepare the following materials and tools before wiring.
•Ethernet cables,
•RJ45 Crimpable plugs, and
•an RJ45 Crimping tool.
Step 1 Use the crimping tool to cut into
the Ethernet cable plastic sheath about 1
inch (2.5 cm) from the end of the cut cable
(Figure 1).
Figure 1 Cut cable end and leave 1 inch
Step 2 Pinch the wires between your
fingers and straighten them out. Carefully
push all 8 unstripped coloured wires into
the RJ45 plug as shown for T568B and
T568A (Figure 2).
