Victron ET340 Energy Meter: Precision Three-Phase Monitoring for ESS and Solar Integration

Advanced Energy Transducer for Grid, PV, and Generator Measurement

The Victron ET340 Energy Meter is a high-accuracy three-phase energy transducer engineered for seamless integration with Victron Energy Storage Systems (ESS) and GX devices. Designed to monitor consumption and generation across all three phases, it provides the critical data needed to optimise self-consumption, manage grid feed-in, and balance loads in residential and commercial installations. With a maximum current rating of 65 A per phase and direct connection capability, this meter is a reliable choice for electricians and system integrators seeking precise energy data without external current transformers.

Unlike generic energy meters, the ET340 offers Class 1 accuracy (EN62053-21) and ±0.5% RDG for current and voltage, ensuring your system makes decisions based on trustworthy measurements. Its dual RS485 ports enable flexible wired or wireless (Zigbee) communication with the Victron Color Control GX or Venus OS, allowing real-time monitoring and control via the VRM portal. Whether you are measuring grid import/export, PV inverter output, or AC generator performance, this meter delivers the granularity required for advanced energy management.

Key Features

  • Three-phase direct measurement up to 65 A per phase, eliminating the need for external CTs in most residential applications
  • Dual RS485 ports for daisy-chaining or redundant communication paths, supporting Modbus RTU protocol
  • Self-powered from the measured voltage (208–400 VAC L-L), simplifying installation and reducing component count
  • Compact 3-DIN module width (54 mm) for space-efficient DIN-rail mounting in distribution boards
  • Bidirectional metering captures both consumption and generation, essential for ESS and net metering setups
  • Wide operating temperature range (-20 to +65 °C) and IP20 front protection for indoor environments

Seamless Integration with Victron Ecosystem

The ET340 is purpose-built for the Victron GX ecosystem. Connect it directly to a Color Control GX via the RS485 to USB interface (cable lengths up to 100 metres supported) or use the optional Zigbee module for wireless communication. Once connected, the meter appears automatically in the GX device list, enabling features like:

  • ESS Grid Metering: Use as the primary grid meter for ESS systems, enabling precise control of grid set points and preventing backfeed.
  • PV Inverter Monitoring: Measure the output of single or three-phase PV inverters, allowing the GX device to log performance and adjust charging strategies.
  • Generator Metering: Monitor AC generator output to manage generator start/stop logic and track fuel consumption.
  • Dual-Function Wiring: In single-phase systems, a single ET340 can simultaneously measure the grid and a PV inverter on separate phases, reducing hardware costs.

For installers, the meter's clear terminal layout and included wiring diagrams simplify commissioning. The front-facing LEDs provide immediate visual feedback on power status and Modbus data transmission, aiding troubleshooting.

Built for Accuracy and Reliability

At the core of the ET340 is a proven Carlo Gavazzi measurement engine, delivering Class 1 kWh accuracy and ±0.5% reading accuracy for current and voltage. This level of precision ensures that your ESS responds correctly to small load changes, maximising self-consumption and reducing unnecessary grid draw. The meter's self-power supply design draws energy directly from the voltage inputs, eliminating the need for an auxiliary power source and reducing potential points of failure.

The robust DIN-rail enclosure is rated IP20 for front protection, suitable for installation in electrical cabinets and meter boxes. With an operating temperature range of -20 to +65 °C and humidity tolerance up to 90% non-condensing, it performs reliably in typical Australian indoor environments, from coastal garages to inland switch rooms.

Applications

  • Residential ESS: Pair with Victron MultiPlus-II and GX device for full home energy management, including time-of-use optimisation and grid outage backup.
  • Commercial Solar: Monitor three-phase solar production and building consumption to verify system performance and identify energy waste.
  • Off-Grid Systems: Measure generator input to automate start/stop based on battery state of charge, reducing runtime and maintenance.
  • Retrofit Projects: Add energy visibility to existing switchboards without major rework, thanks to the compact DIN-rail form factor.

By choosing the Victron ET340, you gain a meter that is fully supported by Victron's documentation, firmware updates, and global community. It is not a generic Modbus meter requiring complex configuration; it is recognised natively by Venus OS, reducing setup time and compatibility risks.

Take Control of Your Energy Data

Equip your Victron system with the ET340 Energy Meter and unlock the full potential of your installation. Whether you are commissioning a new ESS or upgrading an existing setup, this meter provides the accurate, real-time data needed to make informed energy decisions. Add the Victron ET340 to your order today and start monitoring with confidence.

Who doesn't love a unicorn?
Size: 2T, Color: Pink/Unicorn
Cute set but runs a bit big in my opinion for a size 2T. My grandbaby is tall for her age (22 months), but the pants were really long and loose on her, granted she's not chunky, so factor that in. Overall, it's a nice set and the material is soft (especially the pants) and seems like it would keep the little ones warm.
