Project summary
Key takeaways
- Order Group built the EMS behind Skyfri's solar and battery asset management platform; it went into production in June 2024.
- The EMS ran fully offline and controlled battery storage across 7 plants: more than 5 MWh of capacity and more than 4 MW of power.
- It handled charging and discharging, peak shaving, energy trading, DSO requests and export limits on each site.
- The work started with a seven-week technical audit that began on 20 November 2023; the stack was React, Python asyncIO, Databricks and Azure IoT.
Order Group built the architecture and implementation of the EMS behind Skyfri's solar and battery asset management platform. Skyfri Intelligence handles monitoring and data, Skyfri SolarSCADA handles site-level hardware control. A seven-week technical audit of Skyfri's projects and stack, from 20 November 2023 to 7 January 2024, opened the engagement before either team committed to a build. The two teams worked as one continuous unit from January 2024, with no handoff after launch. The EMS Order Group built went into production in June 2024; the work ran across four streams: EMS, Monitoring and Asset Management, Data and Onboarding, and Industrial Design.
The solar sector lost an average of 5.77% of expected production to underperformance in 2024, up from 5.00% in 2023 - about $5,720 per MWdc (megawatt of DC-rated capacity) a year (Raptor Maps 2025 Global Solar Report). Monitoring only shows that loss after it has happened. Catching it before it compounds takes software that acts on the data, which is what the EMS layer Order Group built did. See our Energy Hub for the wider range of monitoring, trading and storage platforms we've built for the energy sector.
The renewable energy asset management solution
An EMS that runs without the internet
Asset management software built for someone else's hardware
Solar monitoring software built for a distributed portfolio
Three layers, three jobs
Skyfri's platform and Order Group's EMS split the work into three layers, each with one job:
- Skyfri Intelligence (monitoring): rolls up production figures, faults and site status across the whole portfolio - shows what happened.
- Skyfri SolarSCADA (hardware control): the site-level layer that talks to inverters and batteries directly.
- EMS, built by Order Group (control logic): decides when to charge, discharge, peak-shave, trade energy and cap exports, running fully offline - acts on what's happening.
Why this was hard to build
An EMS that runs offline makes every decision locally, with no cloud service to check it. It has to make correct, safety-relevant decisions about batteries and grid connections on its own, and it works with several inverter and battery brands at once, each with its own firmware. The same control logic also has to hold for every site's own limits, whatever the size of the site's battery. Four work streams ran in parallel on one team: EMS, Monitoring and Asset Management, Data and Onboarding, and Industrial Design. Onboarding a device in one stream changes what the EMS can control in another, so the team had to hold the whole system in view.
That kind of coordination is hard to sustain through a typical build-and-leave engagement. Order Group and Skyfri didn't run it that way: the engineers who shipped the EMS in June 2024 kept working alongside Skyfri's own team, in the same arrangement that started in January 2024.
Results
The architecture ran in production across all 7 plants from June 2024, and Skyfri and Order Group went on to scope a new EMS project for Hydro Rein.
Order Group's EMS architecture ran in production across Skyfri's live portfolio. The figures below reflect Skyfri's own production data, confirmed by Skyfri:

Questions we get about EMS and monitoring platforms for renewable energy portfolios
-
Renewable energy asset management software tracks and, in the more advanced cases, directly controls a portfolio of solar and battery sites from one platform. Skyfri's platform is one example: Skyfri Intelligence handles monitoring and data, Skyfri SolarSCADA handles site-level hardware control, and Order Group built the EMS architecture that runs underneath both, deployed across 7 plants. Order Group builds this kind of software across the energy sector - see our Energy Hub for the wider range of trading, monitoring and storage platforms we've built.
-
A solar monitoring software platform turns raw data from inverters, meters and sensors into production figures, faults and site status an asset manager can act on. On Skyfri's platform, that data acquisition, processing and display sits inside the EMS stream Order Group built, alongside the control logic it feeds.
-
An EMS decides when a site's batteries and inverters charge and discharge, how they run peak shaving and energy trading, how they respond to DSO (distribution system operator) requests, and how much the site exports to the grid. Skyfri's EMS, which Order Group built and which runs fully offline, does all of this across multiple batteries and inverters on the same site.
-
An EMS needs to run offline because a control decision on a live battery - charge, discharge, cut export at the connection limit - cannot wait on an internet connection that might be down. Order Group built Skyfri's EMS to keep running continuously without one.
-
A real portfolio is rarely built on a single manufacturer, so a platform managing it has to be OEM-agnostic. Skyfri Intelligence and Skyfri SolarSCADA are both built this way, per Skyfri's own product description - designed to read and control hardware neither Skyfri nor Order Group designed.
-
The stack is a React frontend and a Python asyncIO backend, a Databricks data pipeline, and Azure IoT Edge plus Azure IoT Hub connecting to the field, hosted on Azure. That combination has to move data from many distributed sites into one system reliably, which is a different problem from a typical web app backend.
-
A project like this starts with a technical audit because the platform has to work with hardware and site conditions the team does not control yet. Order Group and Skyfri ran a seven-week technical audit from 20 November 2023 to 7 January 2024 before writing production code, which reached the field in June 2024.
-
Asset management means acting on the data: an algorithm enforcing a site's load limit, or an EMS running peak shaving and energy trading across a whole portfolio, instead of a chart someone has to read and act on by hand.
-
Companies managing solar and battery assets at enterprise scale use software like Skyfri's. Skyfri named Hydro Rein, Dominion Energy and Madison Energy Infrastructure as clients on its own site, and operated from Oslo, London, Denver, Bangalore/Hyderabad and Singapore.
-
In one continuous arrangement that started in January 2024: the engineers who built the EMS kept working alongside Skyfri's team after launch and went on to scope a new EMS project for Skyfri's own end customer, Hydro Rein. The infrastructure as code and the new IoT system we work on there are described under legacy software modernization.
