Technical Due Diligence & Design

EU Market Access
Engineering

We bridge the gap between your EVSE hardware and the fragmented reality of European Grid Codes — from National Standards to hyper-local DSO requirements.

The Problem

The "Harmonization" Trap

Compliance is not a checkbox; it is a multi-dimensional matrix. A single hardware SKU must adapt to 27+ national grids and hundreds of local DSO sub-regulations.

01

Continental Baseline

EN 50549-1 / RfG

High-level requirements for generating plants. Necessary for CE marking, but insufficient for grid interconnection approval in major markets.

CE Marking Prerequisite
02

National Derogations

VDE-AR-N 4105 · G99 · CEI 0-21

The "Design Killer". Specific mandates on safety relays, frequency trip times, and islanding detection that physically override EU norms.

Hardware Redesign Risk
03

DSO Local Codes

TAB (Technical Connection Rules)

Hyper-local parameter sets (e.g., Reactive Power Q(U) vs cos(φ)) dictated by local grid topology (E.ON, Enedis, Iberdrola).

Hardware Gap Analysis

PHASE: PRE-PROTOTYPE

A clause-by-clause schematic review against "Worst Case" EU market requirements. We identify missing safety components before you cut steel.

Audit Scope

Safety Chain Redundancy

Verification of dual-series disconnect relays per VDE-AR-N 4105.

Leakage Protection (RCD)

Audit of Type B RCD integration & 6mA DC detection circuits.

EMC & Supraharmonics

Filter topology review for 2–150 kHz range compliance.

Physical Interfaces

Shuttered sockets (France) & PEN Fault detection (UK).

Additional scope includes: Islanding Detection, Thermal Management, Isolation Monitoring, Ingress Protection (IP), Galvanic Isolation, and more.

Grid Code Parametrization

PHASE: FIRMWARE

Delivery of precise JSON/Header files containing the exact trip limits and control curves for specific DSOs, ensuring firmware compliance from first boot.

Deliverables

Ride-Through Curves

FRT/LVRT voltage-time boundaries for G99 vs Continental.

Reactive Power Modes

Look-up tables for Q(U), Q(P), and cos φ(P) control.

Active Power Gradients

Soft-start and ramp-rate limits defined per country.

Ripple Control Logic

Logic mapping for external active power curtailment signals.

Additional deliverables include: Anti-Islanding Settings, Power Quality Limits, Reconnection Sequences, Export Limitation Profiles, Harmonic Current Limits, and more.

Universal Meter Integration

PHASE: SYSTEM INTEGRATION

Reference design support for the "Universal Bridge" interface to ensure interoperability with fragmented European metering standards.

Technical Scope

Universal Interface

Combined RJ12 (P1) / RJ45 (HAN) / RS485 schematic design.

Protocol Parsing

Drivers for DSMR (NL), M-Bus (Nordics), and SML (DE).

SMGW Encryption

Consulting on BSI-certified TR-03109 comms modules (Germany).

MID Compliance

Measuring Instruments Directive requirements for billing-grade data.

How We Work

Engagement Framework

From Schematic to Certificate — a structured, transparent process.

01

Discovery

NDA signed. Transfer of BOM, Schematics (PDF/Altium), and Target Market List.

Day 1–3
02

Gap Analysis

2-Week deep dive. Output: The "Red Flag Report" identifying hardware showstoppers.

Week 1–2
03

Remediation

Delivery of Engineering Change Orders (ECOs) and Firmware Parameter JSON files.

Week 3–5

Certification

We interface with TÜV/DEKRA to answer technical queries during testing.

Market Ready
€20k+
Average cost of a failed certification — test fees, redesign, and lost time-to-market.
3 mo+
Typical delay from a single red-flag issue discovered during type-testing.
92%
First-pass certification rate for clients who complete our pre-compliance review.
Get Started

Don't guess on Grid Codes.

A failed certification costs €20k+ and 3 months of delay. De-risk your product launch before you commit to tooling.
