The Growatt SPM-CT-E is a single-phase smart meter with a 100A current transformer (CT), providing a complete solution for grid export limitation and self-consumption monitoring. Supplied with one CT clamp for simplified wiring, it measures energy flow with Class 1 accuracy and communicates directly with compatible Growatt inverters and storage systems.
- Single-phase smart meter with current transformer (CT)
- Maximum current of 100A
- Class 1 measurement accuracy
The SPM-CT-E is the CT-based version of Growatt's single-phase smart meter, fitting easily over larger tails where a direct-connect meter is unsuitable. Working with the Growatt monitoring portal via ShineLAN or ShineLink, it enables accurate export control and energy management, helping system owners optimise solar self-consumption and comply with grid export limits.
