Please refer to the connection dia-
gram to the left for the correct posi-
tion of the CTs. Clamp the 2 CTs onto
the L1 and L2 wires at the service en-
try point in the main service panel.
The arrows on the CTs must point to-
ward the inverter and be placed on the
proper line based on their number. (CT
1 for L1, CT 2 for L2)
CT Clamp Ratio
The inverter supports three ratios
of CT clamps - 1000:1, 2000:1,
and 3000:1. The CT ratio of the
included CTs is 3000:1.
If you are using a third-party CT,
please ensure that the CT ratio is
one of the supported types. Select
the correct CT ratio setting on the
inverter monitoring page or on
the inverter LCD.
In the above diagram, Black wire is L1,
Red is L2 and Orange is Neutral.
