Growatt SPH4000 Installation Manual

electricity meter, please refer to section 6.3.3 for details.
2. If the cable such as “CT” cable is not used, please do not remove the filler plug from the cable support
sleeve.
Remark:
CT wire (5m in length) specification: RJ45, standard LAN line (one end with 8P modular plug, the other
connected with 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 chart:
Chart 5.24
During the actual operation, please pay attention to the installation of current transformer as the diagram
shows below:
Chart 5.25
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
Notice:
The direction (from K to L) of the arrow on the current transformer is corresponding to the direction of the
current in live wire from Grid to Load. Sensor needs to be placed in the power distribution cabinet.
