EU Declaration of Conformity for Portable Power Stations and Solar Inverters: requirements and checklist
By Ing. Jaroslav Křepelka, Owner, DoC solutions s.r.o. · Updated 22 September 2026
A portable power station combines a large lithium battery, a charger and a 230 V inverter in one box. The 230 V outlet brings it fully under the Low Voltage Directive, and because the battery usually weighs more than 5 kg, it counts as an industrial battery under the EU Batteries Regulation, with obligations that grow in 2027.
This page focuses on portable power stations sold to consumers. At the end we note what changes for inverters connected to the grid, which have additional grid-connection requirements.
Checklist: what your portable power station / solar inverter declaration must contain
- Model exactly as on the rating label, listing capacity and power variants covered
- Name and postal address of the manufacturer (and of the authorised representative, if appointed)
- The statement that the declaration is issued under the sole responsibility of the manufacturer
- Low Voltage Directive 2014/35/EU and EMC Directive 2014/30/EU, or the Radio Equipment Directive 2014/53/EU for models with Wi-Fi or Bluetooth
- RoHS Directive 2011/65/EU
- Batteries Regulation (EU) 2023/1542
- The harmonised standards applied, with year and amendments
- Place and date of issue, name and function of the signatory, and the signature
Which EU legislation applies
| Legislation | Applies? | In the DoC? | Notes |
|---|---|---|---|
| Low Voltage Directive2014/35/EU | Applies | In the DoC: Yes | The 230 V AC outlet and the mains charging input are inside the 50–1000 V AC range. For models with a radio module, RED covers safety instead. |
| EMC Directive2014/30/EU | Applies | In the DoC: Yes | Inverter, charger and DC-DC stages; harmonics and flicker apply when the unit charges from the mains. |
| Radio Equipment Directive2014/53/EU | Depends on model | In the DoC: Yes | Models with app control over Wi-Fi or Bluetooth. RED then replaces the LVD and EMC Directives, and internet-connected models must also meet Delegated Regulation (EU) 2022/30 on cybersecurity, applicable since 1 August 2025. |
| RoHS Directive2011/65/EU | Applies | In the DoC: Yes | Restriction of hazardous substances in electrical and electronic equipment. |
| Batteries Regulation(EU) 2023/1542 | Applies | In the DoC: Yes | A battery weighing more than 5 kg that is not an EV, LMT or SLI battery is an industrial battery under Article 3. Conformity assessment, CE marking and the declaration apply since 18 August 2024; from 18 February 2027 industrial batteries above 2 kWh also need a battery passport. |
| WEEE Directive2012/19/EU | Applies | In the DoC: No | Producer registration in every EU country where you sell, plus battery producer registration. Not part of the DoC. |
Typical harmonised standards
A harmonised standard gives presumption of conformity only in the version cited in the Official Journal of the EU. Always check the current list for each directive before you issue or update a declaration (European Commission: harmonised standards); the versions below are the ones commonly used at the time of writing, and the right selection depends on your product.
Electrical and battery safety
EN IEC 62368-1:2024 + A11:2024 is the current edition, but the Official Journal still cites EN 62368-1:2014 under the LVD.
- EN 62368-1:2014Audio/video, information and communication technology equipment — safety requirements (commonly used for power stations)
- EN 62133-2:2017 + A1:2021Safety of portable sealed secondary lithium cells and batteries
EMC
- EN 55032:2015 + A11:2020Electromagnetic compatibility of multimedia equipment — emission requirements
- EN 55035:2017 + A11:2020Electromagnetic compatibility of multimedia equipment — immunity requirements
- EN 61000-3-2:2014Limits for harmonic current emissions
- EN 61000-3-3:2013Limitation of voltage changes, voltage fluctuations and flicker
Grid-connected solar inverters
Only for inverters that feed into the public grid. Grid connection itself is governed by the network code Regulation (EU) 2016/631 and national rules, usually demonstrated with EN 50549-1.
- EN 62109-1:2010Safety of power converters for use in photovoltaic power systems — general requirements
- EN 62109-2:2011Particular requirements for inverters
Hazardous substances (RoHS)
- EN IEC 63000:2018Technical documentation for the assessment of electrical and electronic products with respect to the restriction of hazardous substances

Common mistakes in portable power station / solar inverter declarations
The Batteries Regulation is missing
The battery inside a power station is regulated in its own right. Declarations that cite only LVD, EMC and RoHS, or still cite the repealed Battery Directive 2006/66/EC, are out of date.
The battery is classified as a portable battery
Above 5 kg the battery is an industrial battery under Regulation (EU) 2023/1542, which changes labelling, take-back and, above 2 kWh, the battery passport from 18 February 2027.
Only cell-level test reports
Cell reports do not cover the battery management system, the inverter, thermal behaviour of the complete unit or the 230 V outlet. The technical file needs evidence for the finished product.
Solar input limits not covered
The declared solar input voltage range must be covered by the safety and EMC tests; high-voltage PV inputs change the insulation requirements.
Grid feed-in declared like an off-grid unit
A unit that can export power to the house or grid needs to meet grid-connection requirements (EN 50549-1 and national rules), not just product safety standards.
What you need besides the declaration
- Technical documentation
- Schematics, BMS description and protection functions, cell data, safety, EMC and battery test reports, risk assessment and RoHS documentation. Keep it for 10 years.
- Transport documents
- A UN 38.3 test summary for the battery; power stations usually ship as dangerous goods class 9.
- Marking and labelling
- CE marking, crossed-out wheeled bin, rating label, and the battery labels required by Regulation (EU) 2023/1542 (the separate collection symbol since 18 August 2025, further labels and a QR code in 2026–2027).
- Economic operator in the EU
- An importer, authorised representative or responsible person established in the EU (Article 4 of Regulation (EU) 2019/1020), identified on the product, packaging or accompanying document.
- Producer registration
- WEEE and battery producer registration in every EU country where you sell.

Frequently asked questions
Is a portable power station battery a portable or an industrial battery?
+
Under Regulation (EU) 2023/1542 a battery that weighs more than 5 kg and is not an EV, LMT or SLI battery is an industrial battery. Most power stations fall into that category.
Does a portable power station need a battery passport?
+
From 18 February 2027, industrial batteries with a capacity above 2 kWh placed on the market need a battery passport, so larger power stations are affected.
Does the Low Voltage Directive apply?
+
Yes. The 230 V AC outlet and mains charging input fall inside the LVD voltage range, unlike a small USB power bank.
What does MyCECheck check on a power station declaration?
+
Whether the Batteries Regulation and all product directives are cited, whether the standards fit a combined battery and inverter, and whether model variants and the EU economic operator are identified. Written report within 48 hours.
