For Solar PV or Storage Battery Measurement
(Requires separately sold CT Cable Set (MKG1510-DE , Optional item))
* When adding to an existing system, switch the main breaker and power connection breaker OFF before installing.
(1) Pass the CT cable and connect it to the CT connector labelled "PV" for measurement of a solar PV system or
the connector labelled "SB" for measurement of a storage battery system, after removing the cover.
(2) Check the phase of the breaker connected to the solar PV or battery being measured, and connect and install
install the CT to I1, I2 and I3 on the CT cable so that they connect to V1, V2 and V3 on the power wire.
To attached multiple solar PV or storage battery systems
The diagram below shows how to combine wiring to measure multiple systems. If such connection sites are not
available, only a single system can be measured. Additionally, measurement will not be possible if the rating is
exceeded (63 A).
