Sol-Ark SA-CT-SM 100 Amp Current Transformer

Sol-Ark 100 Amp Current Transformer Sensors (1 Pair)

The Sol-Ark SA-CT-SM is a precision 100A current transformer (CT) sensor pair engineered to provide real-time AC current monitoring for compatible Sol-Ark hybrid inverter systems. Designed to measure electrical current flowing through main service panels or subpanels, this sensor pair enables the inverter to accurately balance home power consumption, regulate battery charging, and execute zero-export or grid-limiting operation.

Featuring a compact split-core design, these current transformers allow straightforward retrofit installation over existing service entrance conductors without disconnecting main electrical wiring. The sensors relay high-accuracy current measurements to the inverter control board, supporting grid-tied net metering management, peak load shaving, and clean integration alongside home solar circuits and EV accessories.
