A split-core CT may be used for monitoring the power generated and converted to 240V AC for connection to the electric grid. Although the diagram shows a 240V inverter system, the same diagram would apply to 120V inverters.

A SPLIT-60 CT would be used when:

• The CTs is to be installed without disconnecting the inverter.
• CH1 or CH2 is used to monitor the inverter
• Accuracy is desired.

(NOTE: The SPLIT-60 cannot be connected to the AUX channels. If a split CT is required for use with the AUX channels, select the TT-100 CT).

2. Inverter connected to a 240V circuit breaker using a donut style CT.

A donut style CT may be used for monitoring the power generated and converted to 240V AC for connection to the electric grid. Although the diagram shows a 240V inverter system, the same diagram would apply to 120V inverters.

A "Donut" CT is used when:

• There is limited CT space in the panel.
• An AUX channel is used to monitor the inverter
