Included free with every smart meter installation and professional installation. The Shelly Pro 3EM is a DIN-rail mounted energy meter fitted in your consumer unit by our electrician. Wired for single-phase UK homes, it measures grid import, export and solar generation in real time using clip-on current transformers, so your battery follows live household demand and automatically stores surplus solar instead of exporting it. You also get live and historical consumption data in the Shelly app, with at least 45 days of one-minute records stored on the device itself.
