Carlo Gavazzi EM540DINAV23XS1X
A direct-connected two/three-phase DIN-rail energy analyzer for installations up to 65 A where local Modbus data, MID-class energy metering, and compact switchboard fit matter more than an app-first experience.
Carlo Gavazzi EM540DINAV23XS1X
A compact 65 A direct-connected multiphase energy analyzer with local RS-485 Modbus, bidirectional import/export registers, and flexible two- or three-phase wiring for solar, sub-metering, and energy-management projects.
Carlo Gavazzi EM580DINAV23XS2DET
A direct-connected DIN-rail energy analyzer for single-phase and three-phase AC systems, especially EV charger and Eichrecht/MID fiscal-metering applications that need signed Modbus metering data.
Chint DTSU666
A three-phase DIN-rail Modbus meter that makes the most sense in inverter-led solar and export-control installs where compatibility matters more than app polish or a DIY-friendly monitoring experience.
CircuitSetup Expandable 6 Channel ESP32 Energy Meter
An open-source ESP32 energy-monitoring board for Home Assistant and ESPHome users who want configurable CT-based monitoring across mains, solar, subpanels, and branch circuits.
Eastron SDM120CTM
A compact single-phase CT-operated DIN-rail Modbus energy meter for local RS485 monitoring and bidirectional energy measurement.
Eastron SDM120-M
A one-module single-phase DIN-rail Modbus energy meter for low-current circuits, 7 kW EV charger metering, solar import/export metering, and compact panel sub-metering where 45 A direct connection is enough.
Eastron SDM230-M
A compact single-phase DIN-rail Modbus meter for installer-led solar, sub-metering, and panel-monitoring jobs where a 100 A direct-connected format is a better fit than a CT clamp monitor.
Eastron SDM230-Modbus
A compact single-phase 100 A direct-connected Modbus energy meter for DIN-rail installations, local RS485 monitoring, solar import/export visibility, and utility-style sub-metering without a vendor cloud.
Eastron SDM320C-LR
A single-phase 100 A DIN-rail LoRaWAN energy meter for projects that need import/export metering and long-range wireless telemetry without adding an IP-connected app-first monitor.
Eastron SDM54-DM
A compact three-phase DIN-rail Modbus energy meter for 45 A direct-connected circuits, EV charging metering, sub-metering, and import/export energy visibility without external CTs.
Eastron SDM630
A direct-fed three-phase Modbus meter for installer-led solar, sub-metering, and panel-monitoring jobs where reliable DIN-rail hardware matters more than app polish, and where the 100A direct-connected format is actually the right fit.
Eastron SDM630MCT V2
A CT-operated three-phase DIN-rail Modbus energy meter for EV charging metering, solar import/export metering, commercial sub-metering, and larger services where direct 100 A metering is not enough.
Eastron SDM630MCT-ML-TCP
A DIN-rail multi-circuit Ethernet Modbus TCP energy meter for panels, data-center racks, and larger monitoring jobs where one device needs to meter up to four three-phase loads or twelve single-phase circuits through external CTs.
Eastron SDM630M-DI
A direct-connected single/three-phase DIN-rail Modbus energy meter with digital inputs for EV charging metering, sub-metering, and solar import/export monitoring where a 100 A whole-current format is enough.
Eastron SDM72CT-M
A CT-operated three-phase DIN-rail Modbus energy meter for switchboards that need import/export energy, configurable CT ratios, and local RS485 data without a vendor cloud.
Eastron SDM72D-M
A 100 A direct-connected DIN-rail Modbus meter configurable for 1P2W or 3P4W systems, with bidirectional import/export measurement for EV charging, solar and sub-metering.
eGauge EG4015
A professional 15-channel CT energy meter, data logger, and embedded web server for homes, solar sites, submetering, and light commercial monitoring where local data access matters.
Emporia Vue 3 3-Phase Energy Monitor
A three-phase panel energy monitor for small commercial sites, multi-unit properties, and advanced homes that want circuit-level visibility, solar-aware tracking, and a cleaner app-led alternative to generic Modbus metering.
Emporia Energy Vue 3
A panel-installed whole-home energy monitor for households that want app-first visibility into mains and selected circuits, especially when bill reduction, EV charging, and everyday electrification decisions matter more than local-first data access.
Fronius Smart Meter 63A-3
A direct-connected three-phase Fronius smart meter for PV systems that need consumption, feed-in, and dynamic export-control data inside the Fronius inverter and Solar.web ecosystem.
Fronius Smart Meter IP 5kA-3 / 42,0411,0347
A high-current Fronius Smart Meter for commercial or larger PV systems that need CT-based bidirectional metering, local Modbus RTU/TCP communication, and Fronius ecosystem consumption/feed-in visibility up to 5000 A.
