15 kWh home battery: compare prices and brands
A 15 kWh home battery suits a larger household or high own usage, for example from a heat pump. Compare all 15 kWh systems we supply below, incl. VAT and manufacturer warranty.
What does a 15 kWh home battery cost?
A home battery of roughly 15 kWh costs between 1,977 and 7,613 euro including VAT here. We carry 52 models in this class, from 13 to 17 kWh. On the Dutch market the median price in this class is 306 euro per kWh including VAT, with the middle half between 238 and 400 euro. That is measured across 128 offers at 40 shops, from our own price index. One size up is cheaper per kWh: the median in the class above is 299 euro per kWh. The fixed cost of the enclosure, the BMS and the inverter coupling spreads over more capacity.
Which capacity you need depends on your annual consumption, your generation and whether you have a heat pump or an electric car, not on roof size alone. Every battery we sell uses LFP cell chemistry. The same model costs a median 22 percent more at the most expensive Dutch shop than at the cheapest, so compare on model number.
From that date the feed-in credit for solar power largely disappears. A home battery lets you use more of your own generated power yourself, including in the evening, instead of exporting it at a low rate.

Frequently asked questions
Here a battery in this class costs between 1,977 and 7,613 euro including VAT, across 52 models from 13 to 17 kWh. On the Dutch market the median in this class is 306 euro per kWh including VAT, with the middle half between 238 and 400 euro. That is measured across 128 offers at 40 shops, from our own price index. It covers the battery alone, without an inverter and without installation.
For a household with a large solar roof plus a heat pump or an electric car, where consumption simply continues after sunset. Rule of thumb: roughly 1 kWh of battery per 1 to 1.5 kWp of panels, so around 15 to 22 kWp. Without such an extra load you will not empty this capacity on an average day and you are paying for kWh that sit still.
Yes, from this size upward. In this class the Dutch median is 306 euro per kWh and in the class above it is 299 euro per kWh. The fixed cost of the enclosure, the BMS and the inverter coupling spreads over more capacity. That only helps if you genuinely use the extra kWh every day: capacity that sits still does not pay for itself, however good the price per kWh looks.
That depends on the system, and it is the first question to settle, because it is worth hundreds of euros. Some models have an inverter built in and are complete. Others are the battery only and need a hybrid inverter the manufacturer has released for that combination. Voltage and communication protocol both have to match. We maintain a table of 544 manufacturer-approved combinations, each row naming its source document.
Yes. A battery of this type is wired permanently into the consumer unit, which is work for a certified electrician under NEN 1010, and the installer also registers the installation with the grid operator. We supply the hardware; installation you arrange yourself or through our installation partner on request. Wiring it yourself in practice voids the factory warranty and can affect your buildings insurance.
Because the Dutch home storage market has no settled prices yet. The same model costs a median 22 percent more at the dearest Dutch shop than at the cheapest, so comparing on model number usually pays better than switching brand. The middle half of all Dutch offers sits between 249 and 424 euro per kWh. That is measured across 1,020 offers at 61 shops. In this capacity class the middle half of offers runs from 238 to 400 euro per kWh. So always compare on the exact model number and convert the price to euro per kWh including VAT.
