Without a smart meter, a Growatt hybrid inverter can't measure what's flowing in and out of the grid in real time, which means it can't throttle solar production to stay within export limits. The SM-US-200 fills that gap.\u003c\/p\u003e\n\u003cp\u003eUsing RS485 direct communication to the inverter, the SM-US-200 feeds real-time grid import\/export data that the inverter uses to manage self-consumption, limit export, and optimize time-of-use battery dispatch. The two included CTs (current transformers) clamp onto the main service conductors without interrupting power — no rewiring, no shutdown of the home. ANSI C12.20 Class 1.0 accuracy meets utility-grade metering standards.\u003c\/p\u003e\n\u003cp\u003eThis is an accessory component for existing Growatt solar and storage inverter installations.
