enecess E2401-ecoMain Energy Monitor-3-Phase 10-Channel Modular

142,02 € excl. VAT

Turn your distribution board into a smart energy dashboard. The enecess E2401 ecoMain shows how electricity is flowing through your three-phase system — from mains consumption to solar PV, EV charging and individual circuits.

Use live and historical data to identify energy-intensive loads, spot unnecessary consumption and make better decisions about efficiency, solar and future electrical capacity.

  • See where the power goes – monitor mains supply and individual circuits in real time
  • Start with 10 channels – expand up to 40 channels with ecoSub modules
  • Ideal for modern energy systems – monitor PV, EV chargers, heat pumps and other major loads
  • Flexible connectivity – Wi-Fi and Ethernet support
  • Smart-home ready – integrate with Home Assistant and Modbus TCP
  • Make energy data useful – compare usage over time and identify opportunities to reduce waste

What’s in the box

Everything you need to start monitoring your main supply and selected branch circuits with ecoMain.

  • 1 × enecess E2401 ecoMain
  • 5 × 30 A ecoSensors
  • 3 × 100 A ecoSensors
  • 1 × External Wi-Fi antenna
  • 1 × Power cable
  • 1 × Label
  • 2 × Sensor extension cables
  • 1 × User manual, including Quick Installation Guide and record sheet

Easy installation & setup checklist

The enecess E2401 ecoMain is designed for straightforward installation in a distribution board, with DIN-rail mounting, clip-on ecoSensors and guided app configuration. Correct phase identification and matching are essential for reliable operation.

1. Identify the system phases
Confirm the main supply phases L1, L2 and L3, then identify the phase of each branch circuit you want to monitor.

2. Mount ecoMain
Install ecoMain on the DIN rail and connect either the Wi-Fi antenna or Ethernet cable. Optional ecoSub expansion modules can be mounted and connected at the same stage.

3. Connect power and ecoSensors
Connect the power conductors to the correct phases, install the 100 A ecoSensors on the main circuits and the 30 A ecoSensors on selected branch circuits. Sensor direction and phase matching must be checked carefully.

4. Complete the final checks
Before powering the system, verify phase matching, sensor assignment, sensor direction and insulation of unused wires.

5. Set up the enecess app
Add ecoMain to your account, configure Wi-Fi if required, assign circuit names and phases, bind the monitored circuits and start monitoring. Ethernet connects automatically.

Installation notice: Disconnect power before installation. Installation must be carried out by a qualified electrician.

Frequently Asked Questions

The enecess E2401 ecoMain is a modular smart energy monitor for residential, commercial and light industrial applications. It monitors the main supply and individual branch circuits, helping users understand where electricity is being consumed.

Yes. ecoMain supports single-phase 2-wire, split-phase 3-wire and three-phase 4-wire Wye (Y) electrical systems.

ecoMain provides monitoring for 3 main circuits and 10 branch circuits. With ecoSub expansion modules, the system can be expanded to monitor up to 40 branch channels.

Yes. The system is modular, so additional ecoSub units can be added as more monitoring channels are required. This allows users to start with ecoMain and expand the system over time.

Yes. Branch circuits can be assigned to loads such as PV systems, EV chargers, heat pumps and other high-consumption equipment, allowing them to be monitored separately from total site consumption. Each branch circuit is named and assigned to its phase in the app during set-up.

Yes. ecoMain offers Modbus TCP on the local network, and enecess publishes an official Home Assistant integration that reads data directly from the device – ideal for automations and PV-priority load control. Cloud access through the enecess app is also available.

No. Connected via Ethernet, ecoMain obtains its IP address automatically (DHCP) and can be reached on the local network by its host name, so data can be read over Modbus TCP or Home Assistant without the cloud or the app. An internet connection is only needed for the enecess app and cloud features.

Installation must be carried out by a qualified electrician, and power must be disconnected before installation. Correct phase matching between L1, L2 and L3 is essential for reliable operation.

Meter data analysis, visualisation and reporting

We have created an Excel template that can analyse the data and visualise it with graphs. It has the following features and graphs.

  • Maximum power per minute, hour and day
  • Energy usage per minute, hour and day
  • Maximum voltage per minute, hour and day
  • Limit data displayed to a specific day or hour
  • Supports three-phase and single-phase setups

This template and support with importing the data and using the template are included free of charge when purchasing this meter.

The template is very easy to use even for users that is not that familiar with Excel. We have also created step by step instructions document and video.
