Finding a Certified Installer for Your Home Battery

When do you need a certified installer?

A home battery is not always a DIY job. Plug-and-play models such as the Anker SOLIX Solarbank 2 Pro are designed for self-installation and do not require an electrician. However, high-voltage systems (>120V DC), all AC-coupled systems and hybrid inverter installations legally require a certified electrician.

Installing without the required certification also invalidates your insurance and warranty. This article helps you make the right choice.

Required certifications for home battery installation

The following systems require a certified electrician by law:

Situations where an electrician is REQUIRED

• High-voltage batteries (>120V DC) — including Dyness Tower, Huawei LUNA, BYD HVS
• Hybrid inverter installations — connection to an existing solar system requires grid connection
• Batteries with 3-phase connection — requires wiring in the consumer unit
• Backup power (UPS) installations — automatic backup switching requires professional installation

Situations where you can install yourself

• Installations where the consumer unit needs modification — circuit distribution, residual current devices, fuses
• Plug-and-play batteries (e.g. Anker SOLIX Solarbank 2) — connect to existing micro-inverter
• Balcony power stations with a small battery — registration with the grid operator suffices
• Portable power stations for emergency use — no grid connection required

Installation costs: what is normal?

The following systems are self-installable in most cases:

How do you find a reliable installer?

Installation costs vary by region, complexity and the installation company. Always obtain at least three quotes.

• Check BRL 6000-part certification (recognised installer for electrical installations)
• Ask about relevant product-specific training — Anker, Huawei, Dyness have their own installer certificates
• Read Google reviews — minimum 4.3/5 with recent, specific experiences
• Request references from comparable installations in your region
• Check whether the installer provides a written guarantee on the installation (workmanship) — minimum 1 year

What to check after the installation?

Conclusion: never choose the cheapest installer

After the installation, check the following:

A good installer is just as important as the right battery. Incorrect installation voids your warranty, leaves you uncovered in case of damage and can compromise safety. Invest in a certified installer — it is a one-off cost that protects you for the full lifespan of your system.
