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.

Quality & Comfort with Fully Adjustable Support
Team Name: Eden, Size: Queen, Color: Classic
I used to buy pricey, handmade, 100% down pillows—until I learned about the cruelty behind down production. I stopped using down entirely: pillows, comforters, jackets, everything. Then began the long search for something that could at least come close to the comfort of down, I tried Tempur and countless others, but nothing came close. As a side sleeper, I need a pillow that’s high, SOFT, supportive, conforming, and huggable. After wasting money on at least five different pillows, I finally tried the Coop Home Goods Eden Pillow because of its adjustability. The cover is kind of thick, soft, and well‑made (I use a nice cotton pillow cover over it). The filling is soft and high quality. You can customize the height and firmness however you like. It even comes with plenty of extra fill. To my surprise, the shredded foam doesn’t make the pillow clumpy—something every other similar pillow I tried struggled with. The surface stays smooth and soft, and it’s been a total game‑changer. It’s a keeper! I’ve had mine for almost four years now and only needed to add more filling once, about 8–10 months ago. Toss it in the dryer on low with a couple of tennis balls, and it fluffs up like new. And the icing on the cake: outstanding customer service. I highly recommend this pillow and will definitely buy it again

Nothing like the original Eden, don’t buy the name
Team Name: Eden Cool+, Size: King, Color: Classic
I’ve had the original Coop Eden for 5+ years and it has been a great pillow, very comfortable, soft but supportive but when I purchased a new mattress I wanted to refresh my pillow and saw the Eden Cool+ and wanted to give it a try. I figured it could only be better than the original Eden…but it is not. While the outer cover is noticeably cooler to the touch, it is not soft like the Eden. Also, this cool material mostly gets negated if you use a pillow case anyway. The shaped fill material I would also say is “lumpier” for lack of a better word than the shredded material in the original. The combination of the harder, less supple outer casing and the lumpy material just aren’t a good combination. I will say it does sleep slightly cooler than the original Eden but not enough for the sacrifice in comfort. I would absolutely consider going back to the original Eden.

Unmatched Pillow with Unmatched Customer Service!!! 5 STAR ALL AROUND
Team Name: Eden Cool+, Size: King, Color: Classic
## A Dream Come True (and Customer Service to Match!) From the moment I first laid my head on the Coop Eden Cool+ pillow, I knew I'd found something special. It's truly a game-changer for hot sleepers like me. The "Cool+" technology isn't just a gimmick; it actually works to keep my head and neck comfortably cool throughout the night, leading to the most refreshing sleep I've had in years. The adjustable fill is brilliant, allowing me to customize the loft perfectly for my sleep style, which means no more waking up with neck pain. The support is fantastic – it cradles my head without feeling too firm, and it holds its shape beautifully. However, what truly elevates my experience to a full five stars, beyond the exceptional product itself, is the **dedicated and outstanding customer service**. I had a minor issue with my initial pillow (a rare manufacturing defect, which can happen with any product). I reached out to Coop Home Goods, and their response was nothing short of phenomenal. They were incredibly prompt, empathetic, and went above and beyond to resolve the issue swiftly and completely. They genuinely cared about my satisfaction and ensured I was left with a perfect product. It's rare to find a company that not only produces a superior product but also stands behind it with such integrity and genuine concern for their customers. The Coop Eden Cool+ pillow is an investment in your sleep, and knowing that you're backed by such an incredible customer service team makes it an even easier decision. Highly, highly recommend!

Great for side sleepers
It always seems hard to find the perfect pillow when you’re a side-sleeper. This one is great. It comes compressed so you will want to allow some time for it to fully fluff back up. The cover is soft and smooth. I love that it isn’t overstuffed. It provides gentle support and a lot of comfort. I was worried it may be too warm since it is polyester, but it is very breathable and I have not had any issues with feeling overly warm on it. It fits a standard size pillow case. It’s not overly stuffed like some other pillows I’ve tried that were specifically for side-sleepers. I think this world be a great pillow for any sleeping position, really. I wasn’t expecting to love a pillow this affordable, but it gets the job done and I get a good night of sleep. I’ll be purchasing some more for our guest room.

Incredibly Comfortable and Supportive — My New Favorite Pillow!
I wasn’t expecting to love this pillow as much as I do, but the DIORIS large sleeping pillow really exceeded my expectations. From the first night, I noticed a difference in the way my neck and shoulders felt in the morning—less tension, better alignment, and overall more restful sleep. The fill is just the right balance between plush and supportive. It doesn’t flatten out during the night, which is a problem I’ve had with other pillows, especially those that come overstuffed or too soft. This one holds its shape well but still has that cozy, cloud-like feel when you lay your head on it. I’m a side and back sleeper, and this pillow works beautifully in both positions. It’s also large enough that I don’t feel like I’m falling off it during the night, but not so big that it takes over the whole bed. One suggestion: if you’re picky about loft, you might want to give it a gentle fluff or adjust the fill before your first night. But honestly, I didn’t need to do much—it was pretty much perfect out of the bag. Highly recommended if you're looking for a high-quality, comfortable, and generously sized pillow that supports a great night’s sleep!
