Eyedro 3‑Phase Energy Meter EB6‑EW‑E3

This meter delivers real‑time monitoring across three phases, showing kilowatt hours, watts, amps, volts, power factor, and estimated cost. It supports 2.4 GHz WiFi or Ethernet for wired connectivity, making it suitable for networked buildings. It includes 3×200A current transformers for a standard 600V delta or 480V/277V wye setup. Best for facility managers who need live energy analytics and solar generation versus consumption in one place.
Who it’s best for: businesses or property managers seeking a straightforward, real‑time, multi‑phase meter with flexible network options. Why selected: it combines detailed electrical data with cloud friendly connectivity and solid voltage configuration support. Limitation: setup support is provided by Eyedro, which may require initial assistance for first‑time users.
Milbank 200 Amp 3 Phase Meter Socket

This option is a traditional meter socket with built‑in bypass capabilities. It’s best for installers who need a robust physical enclosure to connect a 3‑phase system, especially where service entrance equipment is a priority. It’s a practical choice for utilities or commercial sites that require a straightforward socket solution without onboard data logging. Caution: it relies on supplementary metering hardware for data collection and may require additional CTs or data modules to capture usage data.
DISGE Series 2000 Three Phase Outdoor Kit

Designed for outdoor installations, this 200 A three‑phase kit supports single, two‑wire, or three‑wire configurations. It is best for exterior metering needs in commercial or industrial buildings where rugged enclosures are required. It provides versatile metering capabilities and durable construction. Limitation: configuration support is dependent on the installer’s familiarity with outdoor electrical metering setups.
DAE P254‑200‑S KIT, UL CTEP kWh Smart Submeter

Combines UL/cUL listing with California CTEP approval and 0.5% revenue‑grade accuracy. It supports 3‑phase services (3W or 4W) and includes three CTs. Ideal for landlords, property managers, or facility operators seeking reliable energy data and TOU (Time of Use) billing. Cloud metering via CC2030 gateway is available for remote monitoring. Caution: the installation notes emphasize proper wiring as per diagrams and may require professional electrical work.
DAE P153‑200‑S KIT, 1 Phase 3 Wire Submeter

This kit targets 1‑phase, three‑wire systems with two hot wires and one neutral. It offers revenue‑grade accuracy and supports cloud metering through the DAE gateway. Best for small commercial spaces or multifamily units needing precise energy tracking without a full three‑phase installation. Choose this if your system is predominantly single‑phase and you want TOU and cloud access. Limitation: not a full 3‑phase solution.
Buying Guide
What should you consider before buying a 3‑phase meter?
- System configuration: Ensure the meter supports your voltage configuration (600V delta, 480V/277V wye, or others) and your CT setup (how many CTs, their rating).
- Data connectivity: Decide between WiFi, Ethernet, or cloud integration. For shared networks, wired Ethernet offers reliability; for flexible placements, WiFi is convenient.
- Accuracy and standards: If you need revenue‑grade data, look for UL/cUL listings and 0.5% accuracy, plus TOU reporting capabilities.
- Installation context: Outdoor versus indoor use, enclosure ratings, and whether a bypass option is needed for service continuity.
- Data access: Consider whether you want real‑time dashboards, cloud metering, or local data extraction for tenants or building management systems.
Which meter type fits which buyer?
- Best for real‑time analytics and solar comparison: Eyedro EB6‑EW‑E3 with WiFi/Ethernet.
- Best for service‑entrance applications: Milbank socket with bypass for robust field installs.
- Best for outdoor deployments: DISGE outdoor kit with rugged enclosure and flexible wiring.
- Best for revenue‑grade billing with cloud access: DAE P254‑200‑S KIT.
