Source PDF · page 1

1. System overview

The ecoMain / ecoSub multi-channel energy monitoring system is suitable for residential, small and medium-sized commercial and industrial energy monitoring.

ecoMain / ecoSub energy monitoring system.

Application scenarios

A convenience store aisle — Convenience store

One system: up to 13 × 3P or 40 × 1P meters

Split design: main unit plus expansion units.
Cascadable sub-units, expandable up to 40 channels.
Power and data transmission via a single Ethernet cable.
Voltage sensing via the main unit, with no additional voltage wiring required.

ecoMain and three expansion modules connected together. — Uses internal voltage bus technology.

Features

Modular design with maximum flexibility: Each module offers 10 channels, allowing expansion from 10 to up to 40 channels. Modules can be installed in different areas of a distribution cabinet to optimise space, with expansion when needed to avoid high initial investment.
Modular & scalable: The brochure describes modular hardware supporting dozens to hundreds of circuits with flexible add-on devices and cost-adjustable investment.
No complex wiring: Non-intrusive split-core current sensors measure current; voltage sampling is shared with the system power supply to simplify installation.
Slim-form power sensor: Described as only 12 mm thick for compact cabinets. Adjustable phase and direction improve installation flexibility, with extendable cables to address cable-length needs.
Wide platform compatibility: Native enecess cloud connectivity and open Modbus support for Home Assistant and other systems.
Universal power compatibility: Supports single-phase, three-phase and split-phase circuits in residential and commercial applications.

Brochure wording: The single-system headline specifies up to 40 channels. The separate “dozens to hundreds of circuits” statement is not accompanied by a single-system configuration in this document. The brochure also uses both “12 mm” and a “12.4 mm” graphic label for the slim sensor; these are retained as source descriptions.
