Certifications are the passport that lets a battery storage system cross a border and connect to a market. This reference explains the four marks buyers ask about most — what each one proves, and which region it unlocks.
IEC 62619 is the international safety standard for secondary lithium cells and batteries in industrial and stationary applications. It addresses thermal runaway propagation, electrical safety and mechanical robustness. For a BESS buyer it is the baseline proof that the cells will not fail dangerously under normal and foreseeable abuse conditions. NovaBESS HomeStack, HomeWall and PowerBox all carry IEC 62619.
UN38.3 is the United Nations test for lithium batteries moving by air or sea. It forces cells through altitude simulation, thermal, vibration, shock, external short-circuit, impact and overcharge testing. Without it, a carrier will not ship the battery. Because NovaBESS units are UN38.3 certified, international freight — to the Middle East, Africa, Australia or Europe — moves without that roadblock.
CE marking is the manufacturer's declaration that a product conforms with EU health, safety and environmental law. For battery systems it bundles the relevant EU directives and grants access to the European Economic Area. A CE-marked unit is what most EU distributors and installers expect to see before they will stock or fit it.
The United States and Canada use a different stack: UL 1973 covers the battery itself, and UL 9540A covers the installation's fire-safety behavior (how a system manages thermal runaway). These are not interchangeable with IEC/CE. North America is a higher-certification market — NovaBESS offers UL on selected models, so confirm UL coverage for the specific SKU before quoting US/Canadian projects.
| Certification | What it proves | Unlocks |
|---|---|---|
| IEC 62619 | Stationary battery safety | Global baseline (EU, ME, Africa, AU) |
| UN38.3 | Survives air/sea freight | International shipping |
| CE | EU conformity | European Economic Area |
| UL 1973 / 9540A | North American safety | USA & Canada (selected models) |
| ISO 9001 | Quality management | Procurement credibility |
IEC 62619 is the international safety standard for secondary lithium cells and batteries used in industrial and stationary applications. It covers thermal runaway, electrical and mechanical safety for stationary storage.
UN38.3 is the UN transport test requirement for lithium batteries. It is mandatory for air and sea freight, proving the cells survive altitude, thermal, shock and vibration testing during shipping.
CE marking declares conformity with EU health, safety and environmental requirements, granting access to the European Economic Area market.
North American stationary storage typically requires UL 1973 (batteries) and UL 9540A (system fire safety). These are distinct from the IEC/CE set used in the EU, Middle East and Africa.
This reference summarizes widely used standards as of July 2026 for buyer education. It is not a compliance opinion. Actual requirements differ by country and evolve — always confirm the current certification status of the specific model with NovaBESS or a licensed local assessor before import or installation.
