Home batteries and legislation: what do you need to know in 2025?

Home batteries are becoming increasingly popular. More and more households are combining solar panels with storage, allowing them to use more of their own energy, save money, and become less dependent on the electricity grid. But besides the technical side, there's another important issue: legislation and regulations .

In this blog post, we clearly explain what you, as a consumer, should consider when purchasing and using a home battery. This includes safety requirements, subsidies, mandatory reporting, grid management regulations, and future changes. Clear standards also apply to plug-and-play home batteries , ensuring safe use.

Why are there laws and regulations surrounding home batteries?

A home battery is a powerful system that operates at high voltages and stores a large amount of energy. Therefore, regulations have been established to:

  • to ensure safety for residents
  • to limit fire risks
  • to protect grid stability
  • to ensure correct installation and certification
  • to provide transparency to insurers

These rules are not intended to make things more difficult, but to ensure that battery storage can be used safely and reliably in homes.

1. Installation requirements and certification

✓ CE marking

All home batteries sold in Europe must be CE certified . This confirms that they meet strict European safety requirements for electronics and battery technology. The Anker SOLIX Solarbank Plug & Play systems also comply with these standards.

✓ Installation by a certified professional

In many countries, a battery must be connected by a certified installer. This ensures:

  • correct connection to the fuse box
  • less risk of malfunctions or fire
  • validity of warranty
  • recognition by insurers

Plug & play home batteries are an exception: they are designed for safe installation without an electrician, provided they are used according to specifications.

✓ Safe placement

Depending on the battery type (such as LFP or NMC), guidelines apply for:

  • adequate ventilation
  • distance to flammable materials
  • indoor or outdoor placement
  • minimum free space around

A certified installer automatically takes this into account, but plug & play systems are also supplied with clear installation guidelines.

2. Reporting obligation to the grid operator

In many countries, a home battery must be registered with the grid operator. This is necessary to:

  • the grid operator gains insight into feed-in and peak loads
  • the electricity grid can anticipate increasing storage capacity

For consumers, little will change: registration is often easy via an online form.

3. Subsidies and tax benefits

The regulations surrounding subsidies change regularly. Although direct battery subsidies have sometimes been abolished, there are often still financial benefits:

  • VAT benefits on installation
  • regional subsidies
  • tax benefits for sustainable investments
  • benefits through dynamic energy contracts

It is therefore worthwhile to consult current information or ask your installer for advice.

4. Fire safety and insurance

Home batteries must meet strict fire safety requirements, such as:

  • BMS systems (Battery Management System)
  • overvoltage and temperature protection
  • cell balancing
  • automatic shutdown in case of errors

Insurance

Insurers sometimes ask for:

  • installation certificate from a certified installer
  • battery specifications
  • proof of correct placement

When installed correctly, a home battery can be insured under your building or contents insurance.

5. Legislation regarding feed-in and grid stability

Grid operators are becoming increasingly strict about peak load. Home batteries play an important role in relieving the burden on the grid. Relevant regulations may relate to:

  • maximum return capacity
  • control via an Energy Management System (EMS)
  • smart charging and discharging
  • participation in flexible markets or energy services

In some countries, battery owners are rewarded for “peak shaving” or participating in flex shifts.

6. Future legislation: what can we expect?

Home batteries will become increasingly important in the energy grid in the coming years. Expected developments include:

  • Stricter safety standards — standardized requirements for battery housings, sensors and fire-resistant materials.
  • Smart grid connection (V2G/V2H) — bidirectional charging is becoming more widely available.
  • Rules for energy sharing — such as local energy communities.
  • New subsidies for storage — because storage can prevent grid reinforcement.

What does this mean for you as a consumer?

Installing a home battery is easier than it seems—especially with an installer familiar with all the regulations. The most important thing is:

  • choose a battery with CE marking
  • Have the installation carried out by a certified professional (except for plug & play systems)
  • request for reporting obligation or inspection
  • inform your insurer
  • use an EMS for smart control

With these steps, your battery will meet all requirements and you'll get the most out of your own energy storage.

Conclusion: Clear rules ensure safe and smart home storage

Legislation and regulations surrounding home batteries are evolving rapidly, but they share a single goal: safe, reliable, and efficient storage of sustainable energy. By having your battery installed and registered correctly, you'll immediately comply with the most important requirements.
