We suggest the distance between battery and SPA Series no longer than 1.5m, and The
power line area must be larger than 6 AWG(13.3mm^2).
5.4.3 Connection of CT2 terminal
5.4.4 Connection of CT1 terminal
If the SPA is installed with an existing inverter, there is a CT2 to monitor the inverter
current.
The CT2 terminal connection steps are as follows:
•Unscrew the swivel nut from the cable gland.
•Thread the swivel nut over the “CT2” cable.
•Press the cable support sleeve out of the cable gland.
•Remove the filler plug from the cable support sleeve.
•Route the “CT2” cable through an opening in the cable support sleeve.
•Thread the “CT2” cable through the cable gland.
•Insert the RJ45 plug of the network cable into the “CT2” pin connector on the inverter
until it snaps into place.
•If no other cables need to be installed, lock the waterproof cover to the inverter with
screws.
•Screw the swivel nut onto the waterproof cover.

the cable support sleeve.
•Ct2 wire (5m in length) specification: RJ45, standard LAN line (one end with 8P modular
plug, the other connected with current transformer). But if the length is not enough,
customer can add cable, so the length can be increased to 15m max, the operation is as
follow Fig:
If the cable such as “CT2” cable is not used, please do not remove the filler plug from
Fig 5.21
During the actual operation, please pay attention to the installation of current
transformer as the diagram shows below:
As illustrated above, open the current transformer and you can see an arrow labeled on it
indicating the direction of current. Put the live wire among the under-detection wires
onto the current transformer. After latching the current transformer, the installation has
been finished.

Fig 5.24
The direction of the arrow on the current transformer is corresponding to the direction of
the current in live wire from grid to the existing inverter. Current transformer needs to be
placed in the power distribution cabinet.
There is a CT1 in SPA series monitoring the power consumption situation of residential
users, the CT1
terminal connection steps are as follows:
•Unscrew the swivel nut from the cable gland.
•Thread the swivel nut over the “CT1” cable.
•Press the cable support sleeve out of the cable gland.
•Remove the filler plug from the cable support sleeve.
•Route the “CT1” cable through an opening in the cable support sleeve.
•Thread the “CT1” cable through the cable gland.
•Insert the RJ45 plug of the network cable into the “CT1” pin connector on the inverter
until it snaps into place.
•If no other cables need to be installed, lock the waterproof cover to the inverter with
screws.
•Screw the swivel nut onto the waterproof cover.
