Distributed energy · edge gateway

Open EMS

AI-driven optimisation of batteries, charging stations, solar installations and heat pumps, with a strategy you define.

Any brand of device connects.

Core capabilities

Device integration, strategy execution and delivery, all on this gateway.

  • Power market and VPP ready

    Prepared for FCR / mFCR ancillary services, with a pluggable aggregator interface.

  • Commissioned in 5 minutes

    Power up, connect to the network, add devices — it is running.

  • White-label ready

    OEM/ODM partnership: delivered without our branding, with the interface and copy in yours; scope agreed per project.

  • Runs 24/7, keeps a month locally

    Runs continuously and retains about a month of history on site.

  • AI scheduling

    Improves on the automatic policy to further optimise charging and load.

  • AI-assisted device onboarding

    About an hour to bring a new device model online.

One gateway, many kinds of site

Local policy runs per site, independently of the others.

  • A ground-mounted PV array with a grid-tie inverter on a concrete equipment cabinet

    PV grid-tie

    Inverter output and yield are collected on the gateway itself, so live data stays on site.

  • An outdoor battery cabinet with its door open, showing racked battery modules

    Battery storage

    Charge and discharge windows are decided by a local policy and track PV output in real time.

  • A row of AC charging posts in a car park

    EV charging

    Coordinated with site load so charging lands in a better window.

  • Two air-source heat pump outdoor units against a building wall

    Heat pumps

    Brought under the same local policy and scheduled against time-of-use tariffs.

  • A microgrid site with a solar carport, distribution cabinets and cable trays

    Microgrid

    Multiple device types coordinated on one policy; a single site runs without any cloud.

A full interface, on site

Live status and policy configuration all sit in the on-site interface, independent of any cloud platform.

  • Local web overview: energy flow diagram and live PV, battery, load and grid power

    Live overview

    Energy flow, four live power readings and strategy status are all on the local web page, which opens even without a network connection.

  • Local web configuration page: time-of-use periods and peak-shaving and self-consume modes

    Policy configuration

    Time-of-use windows and peak-shaving parameters are set on the local page, not pushed down from a cloud.

The current hardware configuration as photographed. The DPE100 target configuration converts the two RS232 ports to RS485; the remaining interfaces are unchanged. The silkscreen in this photo shows the current configuration; units will ship with the target configuration.

How the data flows

Southbound is a local loop; only northbound is optional.

What "open" means here

Your cloud, your data and your revenue were always meant to be yours.

  • Runs independently on site

    The gateway runs in full on its own. Local policies act in real time, so the site stays under control even when the network drops.

  • Vendor-neutral

    We sit outside every energy equipment vendor, so dispatch advice stays neutral.

  • Data stays on site

    Data lives locally by default. Whether it leaves, what leaves, and who receives it are all decisions your policy makes.

  • Fast integration of any device

    New device types arrive as self-contained device packs, so adding a brand never means rewriting the system around it.

  • Fast extension of any business logic

    Rule-engine packs extend what the gateway does, and rules stay independent of one another, so changing one leaves the rest untouched.

  • Fast VPP onboarding

    Virtual power plant integration is plugin-based, so connecting to aggregators and power markets leaves the core alone.

Maximising revenue

Going from self-consumption to trading in power markets can be done in stages.

  • Lower initial investment

    Start from the smallest configuration that works and put budget where it actually earns.

  • Scale in stages

    Add devices as the business grows, so the investment curve follows the revenue curve.

  • Standalone site operation

    Standalone operation is the default; centralised multi-site management is an option.

  • AI-assisted dispatch revenue

    The on-site policy engine adjusts dispatch to real conditions locally.

  • Independent return analysis

    Returns are assessed independently, uninfluenced by any equipment vendor's position.
