Track electricity consumption and generation with real-time readings, local data storage and network connectivity, helping you understand how circuits and equipment use energy.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDetailed Energy Monitoring\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eMonitor voltage, current, active and apparent power, accumulated energy and power factor per phase. Current measurement supports up to 120 A per phase and the neutral, while four-quadrant measurement supports photovoltaic monitoring applications. The product information specifies Class B active-energy accuracy based on manufacturer testing.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eLocal Records And Export\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eAt least 45 days of measurements are stored locally at one-minute resolution for later retrieval. A real-time clock maintains record timestamps during connection interruptions. Recorded data can be exported as CSV for PQ values or as JSON through RPC.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFlexible Connectivity\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eEthernet, 2.4 GHz Wi-Fi and Bluetooth provide connection options for setup and integration. Use the embedded web interface to view readings and adjust settings, or integrate with compatible automation systems through MQTT, HTTP and WebSocket. The product information lists Matter support as requiring an update to compatible firmware.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eAutomation And Contactor Control\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eScripting and webhooks support tailored automation. There is no built-in relay: switching an external contactor requires a separate compatible Shelly add-on. The meter's 120 A measurement capability is not a direct load-switching rating.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCompact DIN Rail Installation\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe plastic housing measures 94 × 19 × 69 mm and operates from a 100–260 V AC, 50\/60 Hz supply. Installation and electrical protection must follow the manufacturer's safety instructions and should be handled by a qualified electrician.\u003c\/p\u003e","brand":"Shelly","offers":[{"title":"Default Title","offer_id":55389252026707,"sku":"0041998","price":139.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1076\/1850\/0947\/files\/square-image_b5e8b377-a178-46a3-a934-e5c4a834fb65.jpg?v=1792064179","url":"https:\/\/www.klikk.com.mt\/products\/shelly-pro-3em-120a-v2","provider":"Klikk Malta","version":"1.0","type":"link"}
