Are home batteries getting cheaper?
Every battery from the table, by the month it came on the market in Europe and its price per kWh today. We show € per kWh rather than € per kW: storage makes up most of the price, while the power is often capped by the inverter or the grid rules.
- Plug-in battery
- Installed battery
How to read the table
- Power
- How many kilowatts the battery can charge or deliver at once. It decides whether the battery can fully cover an evening peak, such as cooking or the washing machine. For a plug-in battery, this is its power on a dedicated circuit.
- Capacity
- How much energy the battery stores. When the manufacturer states a lower usable capacity, it is shown below. The bar shows how large the battery is next to the others.
- Efficiency
- How much of the energy you put in, you get back out (the round-trip efficiency), as the manufacturer states it. AC is measured from socket to socket, DC in the battery alone (which gives a higher figure) and solar → home from your solar panels through the battery to your home. For most plug-in batteries the manufacturer states no efficiency; in the measurements by Energienerds (in Dutch) they reached roughly 78 to 88% at 800 W.
- Price
- What a webshop asked for the battery itself, with 21% VAT. An installed battery also needs installation and often a hybrid inverter. When an installer fits the battery in a home older than 10 years, you pay 6% VAT instead of 21%. In Belgium you also pay a Bebat recycling fee, about € 200 for a 5 kWh battery.
- € per kWh and € per kW
- The price divided by the usable capacity (or by the capacity, when the manufacturer states no usable capacity) and by the power. This lets you compare batteries of different sizes.
- Plug-in or installed
- You plug a plug-in battery into a socket yourself. It must be on the Synergrid list and usually delivers up to 800 W through an ordinary socket; more is only possible on a dedicated circuit. From 800 W you register it with Fluvius within 30 days; below that you don't have to if you have a digital meter (the rules, in Dutch). An installed battery is fitted by an installer, who also registers it.
- Control
- How the battery charges and discharges, shown with three icons. The house: it follows your meter, charging with your surplus solar power and supplying what your home uses. The clock: it charges and discharges at fixed times you set, useful with a day and night tariff. The chart: it plays a dynamic tariff by itself and charges when power is cheap, in the manufacturer's app or through a supplier that steers the battery for you (in Belgium, Frank Energie). A blue icon is a feature you can simply switch on; a struck-through icon is not, or for a dynamic tariff only with Home Assistant or EVCC; a faint icon means we found no reliable source. Point at an icon for the details. Whether a battery can limit your quarter-hour peak for the capacity tariff isn't shown yet: we found too few reliable sources for it. Checked on 03/11/2026.
Which battery suits you?
You want to start small
You set up a plug-in battery yourself, it usually costs the least per kWh and it moves house with you. It doesn't fully cover large appliances such as a hob or a heat pump.
You have many solar panels, a heat pump or an electric car
An installed battery has more capacity and power: it stores more solar power and also helps out with large appliances. Count in the installation and possibly a hybrid inverter.
You have a dynamic contract
Then you earn on the difference between cheap and expensive hours. Look closely at the efficiency: at 80% you lose a fifth of the energy you charge, and that comes off your profit.
What a battery earns you depends on your consumption, your solar panels and your contract. The calculator works it out for you for free, quarter-hour by quarter-hour.
