The
One box.
One standard.
Zero grid headaches.
The FLEXBOX is our new plug-and-play hardware
that turns grid complexity into a competitive advantage for Charge Point Operators.
Designed for high-power charging hubs in Germany & Austria, the FLEXBOX combines on-site load management, DSO integration and local asset networking into a single, standardised box ready to deploy anywhere, regardless of regional DSO requirements.
The challenges
Rolling out charging hubs in DACH is no longer just about power availability.
It’s about grid compliance and speed and that’s where things break.
Fragmented DSO
Germany alone counts 800+ Distribution System Operator, each with its own grid codes, interfaces, and approval logic.
Non-standard technical requirements
Modbus, analogue I/O, digital signals, different telecontrol devices every site can become a custom engineering project
Planning delays & rising costs
Grid approval cycles slow down rollouts, inflate budgets, and increase dependency on scarce engineering resources.
Future uncertainty
20–30% of sites already require Grid compliance today and the number is steadily increasing. Many CPOs are forced to retrofit later, at high cost.
Let’s change that
The Solution
A standardised DSO interface
by design
The FLEXBOX provides a standardised technical interface to DSOs, abstracting local grid specifics behind one consistent layer.
Instead of adapting every site to regional grid rules, CPOs deploy the same hardware and technical model everywhere regardless of local DSO requirements.
Plug-and-play commissioning at scale
By abstracting DSO complexity, the FLEXBOX enables plug-and-play commissioning across regions. This significantly reduces site-specific engineering, testing, and DSO integration effort, no custom site designs, no repeated testing cycles, no bespoke integrations per grid area. The result: faster grid approval, lower rollout risk, and predictable deployment costs
One local network for all energy assets
The FLEXBOX connects and orchestrates all on-site energy assets via a local network: EV chargers, Battery Energy Storage Systems (BESS), Power meters, Solar PV systems. All assets are managed as one coordinated system, enabling optimal operation under grid constraints
Local energy intelligence - cloud-resilient by default
Load management and energy management run locally on the FLEXBOX server. This ensures reliable, deterministic operation even if cloud connectivity is unavailable, especially critical during DSO activations or grid events. The cloud enhances visibility and optimisation, but the FLEXBOX keeps the site running
Customer case
“Expanding into Germany meant facing grid requirements we hadn’t dealt with before. The FLEXBOX allowed us to comply fast, without redesigning our sites or slowing down our rollout.”
Germany
ELECTRA deployed FLEXBOX on their first German charging hubs to meet local Grid Compliance requirements. Results:
→ Fast grid approval
→ No custom site engineering
→ Standardised rollout across regions
→ Confidence to scale further in DACH
Value proposition & benefits
Why the FLEXBOX
The FLEXBOX delivers four core outcomes for large-scale CPO operations: reliability, cost efficiency, execution speed, and future readiness.
Lower cost & engineering effort
Standardised hardware and DSO interfaces reduce engineering, installation, and integration effort, lowering both CapEx and OpEx.
Faster & predictable rollouts
One hardware standard and one commissioning model enable repeatable, predictable deployments, minimizing rollout delays and execution risk
Operational reliability & control
Load and energy management run locally on the FLEXBOX, ensuring deterministic site control, even without cloud or backend connectivity
Future-proof grid & energy use cases
The FLEXBOX is designed for evolving DSO requirements and future energy use cases, including bi-directional power flows and flexibility markets, without site redesigns.
