Household storage
Domestic battery storage is judged on three things: usable capacity, the power your connection allows and the total cost. PowerHub ONE covers 2.4 to 12.0 kWh with published prices from €1,199.
Usable capacity, the power available through your connection, expandability and the published warranty framework. Model names alone say little about actual capacity.

Configurations are built from 2.4 kWh modules and cover 2.4 to 12.0 kWh of actual battery capacity.
Extra modules raise energy, not the power limit of the connection mode: up to 800 W standard, up to 2.4 kW peak on a dedicated circuit.
Metering equipment and any fixed electrical work are confirmed for the property and sit outside the unit price.
The published framework covers 10 years, 6,000 cycles and at least 70% remaining capacity under the published warranty conditions.
In depth
A fair comparison of domestic battery storage uses the same definitions throughout: actual usable capacity in kWh, power with its connection conditions, whether capacity can be expanded, the metering method, the published warranty framework and the installed cost.
Commercial model names are frequently rounded. Always read the actual capacity figure next to the label before comparing two systems.
PowerHub ONE is a modular AC-coupled platform: five configurations from 2.4 to 12.0 kWh of actual capacity, standard operation up to 800 W on a suitable outlet and up to 2.4 kW peak on a dedicated circuit.
Warranty terms belong in the comparison too. Read scope and exclusions, not just the number of years, because that is where systems differ most.

Customer reviews
We only publish reviews from customers who actually bought and used the product. As long as there are no reviews, no score is shown here — we never invent one.
Once customers have their PowerHub ONE in use, we invite them to share their experience and the average appears here.
Customers receive a personal invitation after delivery. Every review is published unchanged, including critical ones.
Frequently asked questions
It depends on the energy you want to shift per day and the power your connection mode allows.
Yes, by adding 2.4 kWh modules within the supported configurations.
Fixed electrical work, including a dedicated circuit, must be done by a qualified electrician.
