EN 50549 Test Tools
Comprehensive Automated Testing for EN 50549-1, -2, and -10 Compliance
QualityLogic’s EN 50549 Test Tools provide a complete, automated solution for Distributed Energy Resource (DER) manufacturers, inverter OEMs, and accredited test laboratories that must demonstrate compliance with the European grid code standard EN 50549. This standard governs the connection and operation of generating plants, including energy storage and Vehicle‑to‑Grid (V2G) capable systems to public distribution networks below 110 kV across the EU and UK.
With decades of leadership in DER interoperability and grid code testing, QualityLogic extends its proven IEEE 1547/UL 1741 SB test architecture to support EN 50549‑1, EN 50549‑2, and EN 50549‑10 requirements, giving organizations a reliable, efficient, and repeatable path to compliance.
Introducing QualityLogic’s EN 50549 Test Tools
Built upon the same world‑class framework trusted for IEEE 1547 and UL 1741 SB certifications, the EN 50549 Test Tool adds:
- Automated execution of EN 50549‑1 (Type A), EN 50549‑2 (Type B/C/D), and EN 50549‑10 test requirements
- Flexible test sequencing and parameter configuration
- Automated communication and control of power analyzers, grid simulators, oscilloscopes, and other lab equipment
- Custom test creation and editing through both GUI‑based and JSON script‑based configuration
- Optional V2G/EV‑specific testing capabilities aligned with 50549‑10 requirements
This unified test environment enables fast adoption by teams already using QualityLogic’s 1547/SB test tools and minimizes training time.
Why EN 50549 Compliance Matters
Grid operators across Europe require DERs, including PV inverters, hybrid inverters, generators, storage systems, and V2G‑enabled EVSE, to demonstrate functional behavior under normal and abnormal grid conditions. EN 50549 compliance ensures:
- Stable and reliable grid operation
- Safe interconnection and disconnection behavior
- Proper voltage, frequency, and reactive power support
- Disturbance ride‑through capability
- Alignment with future DER interoperability and communication requirements.
QualityLogic’s EN 50549 Test Tools help OEMs and test labs complete certification efficiently while reducing manual setup, human error, and interpretation ambiguity.
Powerful Script Editor & Custom Test Creation
The new Script Editor enables:
- Drag‑and‑drop customization of test logic
- Editing or extending baseline EN 50549 test steps
- Creation of entirely new test sequences
- Parameter overrides for testing national variants (e.g., G99 in the UK)
- Ability to adapt the same test framework for AS 4777, IEEE 1547, or other grid codes
This flexibility supports both accredited labs and OEM R&D environments that must test proprietary features, pre‑compliance functions, or evolving grid code rules.
