There are two AC terminals and the assembly steps for both are the same
(AC backup port and AC grid port).
4.4 Assemble
the
AC
Cables
Step 1. Please unlock the 4*M4 screws on the AC ports protection cover as shown in the below
figure.
Step 2. Insert the AC grid cables and AC backup cables into the corresponding water-proof swivel
nut on the cover, (Break the plastic film on it). Make sure you use a cable within the correct
specifications as shown in the table below.
Remove a length of 40mm of the cable jacket and strip the wire insulation to a length of 10-12mm.

4.5 CT Installation
RAI-3K-48ES-5G inverter requires a CT to measure the power flow to/from the grid.
This will provide information to the RAI-3K-48ES-5G inverter about when to charge or discharge
the battery thus maximizing the self-consumption rate.
