SLEER

One meter for many independent circuits.

SLEER is an aggregated multi-channel electricity meter. It distributes, measures and manages independent circuits inside a single integrated architecture, so a multi-circuit installation needs fewer devices, fewer connections and less space.

What an aggregated meter changes

In a conventional multi-circuit system, every added circuit brings more meters, current transformers, terminals and wiring. SLEER is designed to remove that growth.

  1. Fewer devices

    Distribution, aggregation and measurement happen in one product instead of several separate meters and components.

  2. Less wiring and fewer connections

    A shared architecture cuts the terminals and cable runs that a panel full of individual meters needs.

  3. Smaller installation footprint

    One compact unit replaces rows of meters, which frees panel and room space.

  4. Simpler commissioning

    One device to install, configure and commission, not one per circuit.

  5. One stream of data

    Every circuit is measured independently, and all readings come out through one common communication path.

  6. Built-in circuit management

    Processing, circuit management and output control sit in the same architecture as the measurement.

Integration, not just more channels

The value of SLEER is the complete system around a multi-circuit project, not the channel count on a datasheet.

How it works

Power enters once, and each circuit is distributed, measured and controlled inside the same unit.

Modern multi-storey residential building

Made for buildings with many circuits

Multi-unit residential buildings, commercial and office buildings, hotels and accommodation, and educational facilities and universities. Selected industrial applications follow at a later stage.

Our customers are building owners and developers, facility managers, engineering companies, system integrators and electrical contractors.

Four areas of innovation

Beyond the integrated architecture, SLEER's development focuses on measurement accuracy and long-term stability.

  1. Stable calibration

    Several parameters are analysed together to tell temporary environmental changes from real measurement drift, so accuracy holds for longer and frequent recalibration is less needed.

  2. Protected measurement path

    A short circuit is detected and the current transformer is disconnected from the sensitive measurement path before it saturates.

  3. Redesigned current busbars

    A triangular busbar structure and sinusoidal cable-connection slots improve current distribution and reduce resistance, heat and electromagnetic interference.

  4. Active EMI mitigation

    Persistent and transient electromagnetic interference is identified, classified and corrected so it does not affect the device's operation.

A phased plan for growth

We prove the product first, then grow production and service capacity in line with confirmed demand.

  • Year 1Engineering, testing, validation and a real-world pilot.
  • Year 2First commercial projects and limited-volume sales.
  • Year 3 onwardGrowing volumes, wider partner network and a larger team.
