Plug-in home battery: how we work

What you get

A 2.4 kW BMS module with one to three battery modules of 4.8 kWh underneath it. The inverter is built in, so there is no separate box. The set is AC-coupled: it measures what goes in and out of the house and charges itself with whatever your panels have to spare.

Why the plug matters

A hard-wired system means opening the fuse box and adding a circuit. This set does not: it goes into an earthed socket or onto an existing circuit. That saves installation work and makes it portable if you move. The trade-off is that the power is limited by what a socket can carry.

We check the circuit first

A battery that supplies power for hours loads the circuit it sits on. If a freezer or washing machine already hangs off it, the breaker will trip. We measure what the circuit can take and check that the earthing is sound; in houses built before 1960 that is often not the case.

Smart charging through the app

The AEG app works on tariff: on a dynamic contract the set charges when power is cheap and discharges when it is expensive. On a fixed contract it is purely about using as much of your own solar power as possible.

Prices include VAT. One stack holds up to three batteries; more capacity means several stacks side by side, up to 28.8 kWh. We come out to check the circuit and the earthing before the set is put into use; what that costs is stated in the quote.

Frequently asked questions about plug-in home battery

Question not answered here? Call or message us and we will think it through with you, free of charge.

What does it cost in total?

The set with one 4.8 kWh battery costs €1,490 including VAT. Every extra battery is €1,200 including VAT, so 9.6 kWh comes to €2,690 and 14.4 kWh to €3,890. Our check of the circuit and the earthing comes on top; that price is stated in the quote beforehand.

How far can I expand?

One stack holds up to three batteries, 14.4 kWh together. Beyond that you place stacks side by side; in parallel up to 28.8 kWh is possible. At that size a hard-wired system is usually the wiser choice.

Does it work in a power cut?

No. The moment the grid drops out the set switches off, just like your inverter. That is a safety requirement. If you do want backup power, you need a hard-wired system with extra switchgear in the fuse box.

Is it safe against fire?

The cells are LiFePO4, a chemistry that is less prone to thermal runaway. AEG supplies an aerosol fire suppression kit as standard. We install the set to the regulations and in a place where the heat can escape.
