OPEN STANDARDS FOR EUROPE'S DECENTRALIZED ENERGY FUTURE.
SunSpec Europe is a neutral nonprofit platform translating European research and innovation into practical, interoperable solutions — so solar, batteries, EVs, and flexible loads can work together across borders, manufacturers, and policies.
BORN FROM THE CALL OF EUROPE'S RESEARCH COMMUNITY
Research communities across Europe asked SunSpec to support the adoption of IEEE 2030.5
and Secure SunSpec Modbus for the continent’s most pressing energy challenges.
ENERGY COMMUNITIES
Enabling local, citizen-led energy sharing across the European Union.
National grid security
Hardening Poland’s grid against modern cyber and operational threats.
Flex Connect & dynamic pricing
Powering Germany’s flexible interconnection and time-of-use markets.
Building Performance Directive
Aligning building energy systems with the European Directive on Building Performance.
Cyber Resilience Act
Helping device makers meet rigorous EU cybersecurity obligations.
A decentralized grid speaks too many languages.
Europe’s energy system is rapidly decentralizing, with growing deployment of solar, batteries, EV charging, and flexible loads.
These technologies often use incompatible communication systems — increasing integration costs and operational complexity.
SunSpec Europe bridges existing, widely adopted protocols and enables coordination , so devices, operators, and markets can finally speak as one.

We promote the protocols already trusted around the world.
SunSpec Europe champions open, globally adopted communication standards so that energy devices from different manufacturers can work together — out of the box.
Secure SunSpec Modbus
IEEE 1547
IEEE 2030.5
And other open standards
A neutral platform where the whole ecosystem meets.
SunSpec Europe convenes the people who shape the energy transition — manufacturers,
utilities, research institutions, and regulators — and turns European research and innovation
into practical, interoperable solutions for the energy market.
Manufacturers
Build once, ship across Europe.
Utilities & DSOs
Coordinate distributed energy at scale.
Researchers
Translate ideas into standards.
Regulators
Anchor public policy in open tech.
ALIGNED WITH EUROPE'S GOALS.
SunSpec Europe supports European policy objectives for grid reliability, cybersecurity, and renewable energy expansion — channeling rigorous, open standards into the EU’s most important energy transitions.
A GERMAN NONPROFIT, IN THE PUBLIC INTEREST.
Establishing SunSpec Europe as a German nonprofit association ensures independence, transparency, and alignment with public interest objectives — so every member, large or small, gets a fair seat at the table.
What members & the market gain.
Open standards aren’t just good engineering — they’re good economics, good policy, and good for the climate.
Reduces integration costs & shortens time-to- market
Spend less engineering effort wrestling with bespoke protocols, and ship interoperable products faster across borders.
Eliminates vendor lock-in
Open, multi-vendor standards mean utilities and end customers stay in control of their own infrastructure.
Lowers regulatory risk & encourages investment
Products built on standards-aligned communication are easier to certify — and easier for European markets to trust.
Creates mappings & partnerships across protocols
We do the hard work of bridging multi-protocol environments — so customers don’t have to choose between ecosystems.
Help shape the open energy stack of Europe.
Whether you build inverters, run a grid, or write policy — SunSpec Europe is where interoperability gets done.
