It is the essential component that enables the SigenStor EMS to make intelligent, load-aware decisions: without it, the system cannot see what the home is consuming or exporting, so advanced functions including dynamic load management, solar surplus EV charging, and export limitation are unavailable. Three external 120A split-core current transformers (CTs) are included in the box, making this a complete, ready-to-install metering solution for three-phase residential and light commercial supplies.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"sgs-stat-bar\"\u003e\n    \u003cdiv class=\"sgs-stat\"\u003e\n\u003cdiv class=\"num\"\u003e3-Phase\u003c\/div\u003e\n\u003cdiv class=\"lbl\"\u003e3P3W \/ 3P4W\u003c\/div\u003e\n\u003c\/div\u003e\n    \u003cdiv class=\"sgs-stat\"\u003e\n\u003cdiv class=\"num\"\u003e120A\u003c\/div\u003e\n\u003cdiv class=\"lbl\"\u003eCT Rating\u003c\/div\u003e\n\u003c\/div\u003e\n    \u003cdiv class=\"sgs-stat\"\u003e\n\u003cdiv class=\"num\"\u003e±1%\u003c\/div\u003e\n\u003cdiv class=\"lbl\"\u003ePower Accuracy\u003c\/div\u003e\n\u003c\/div\u003e\n    \u003cdiv class=\"sgs-stat\"\u003e\n\u003cdiv class=\"num\"\u003e100ms\u003c\/div\u003e\n\u003cdiv class=\"lbl\"\u003eData Refresh\u003c\/div\u003e\n\u003c\/div\u003e\n    \u003cdiv class=\"sgs-stat\"\u003e\n\u003cdiv class=\"num\"\u003eRS485\u003c\/div\u003e\n\u003cdiv class=\"lbl\"\u003eInterface\u003c\/div\u003e\n\u003c\/div\u003e\n    \u003cdiv class=\"sgs-stat\"\u003e\n\u003cdiv class=\"num\"\u003eIP51\u003c\/div\u003e\n\u003cdiv class=\"lbl\"\u003eProtection Rating\u003c\/div\u003e\n\u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003ch2\u003eWhat the Power Sensor Enables\u003c\/h2\u003e\n  \u003cp\u003eThe Power Sensor sits at the grid connection point (typically in or adjacent to the consumer unit) and feeds real-time import\/export data to the SigenStor Energy Controller via RS485.
