Note:
1. Meter and CT can’t be installed at same time, please set the sensor model when
selecting CT or electricity meter, please refer to section 6.3.3 for details.
2. CT max current is 125A, please do not exceed this range.
3. 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:
4. 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, in the USA , there are
two live wires need to add current sensor, do not add the current sensor in the same
live wire. After latching the current transformer, the installation has been finished.
Notice:
1. 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.
2. Meter must be provided by Growatt. If not, maybe meter can't communicate with
SPH inverter.
3. The more detail description of meter installation, please turn to meter user manual.
4. In USA or other split phase market. Two current sensors must add to the separated
two live wires.
