The times when you effortlessly earned money with solar panels on your roof seem over. With the phasing out of the netting scheme and the popping up returns, it is suddenly a lot less attractive for many households to return solar power. The HomeWizard Plug-in Battery is cleverly responding to this. This compact home battery helps you to use as much of your self -generated electricity yourself. Without an installer, without breaking, and without hassle. For a price of 1395 euros Do you have the device at home. But how well does that work in practice?
A battery with a mission
The idea behind the plug-in battery is clear: if your solar panels generate more power than you need at that time, save the surplus. As soon as the sun undergoes whether your consumption is higher than the generation, that stored energy comes in handy again. This way you bypass the disadvantages of supplying back, and you reduce your dependence on the grid.
The system works together with the homewizard P1 meter – a dongle of 24.95 euros that you connect to the smart meter. This ensures that the battery only loads if there is a surplus, and only discharges if needed. You don’t have to do anything else for that; The app controls everything automatically.

Technical specifications (in a nutshell)
- Capacity: 2.7 kWh per battery
- Charging and discharge capacity: 800 Watt
- Expansion: up to 4 batteries stackable (10.8 kWh total)
- Efficiency: 78–82% Round trip (in practice around 80%)
- Sound level: 32 dB (refrigerator level)
- Standby consumption: 1 Watt
- Lifespan: 15 years or 6000 load cycles
- Warranty: 7 years or 4000 cycles via the Swap Service
If you place multiple batteries, you can increase the discharge capacity – up to 3200 watts at four batteries. But beware: with four batteries you need your own group in the meter cupboard.
Install without an installer
What distinguishes this battery is the ease with which you use it. No installer needed, no hassle in the meter cupboard. You connect the P1 meter to your smart meter, connect it via the HomeWizard Energy app, and plug the battery into an ordinary socket. After a short configuration in the app, the installation is ready – within ten minutes.
Just think carefully about the location: the battery must be inside, with some space around (10 cm sides, 50 cm top). It makes a soft buzzing sound, similar to a fridge – so prefer not to be next to your bed.

App in top shape
The HomeWizard Energy app is surprisingly good. Where many Smart Home apps struggle with clarity or stability, they score points. You get direct feedback about what happens: when the battery loads, how much is in it, and how your consumption develops. The graphs are clear and you quickly gain insight into your own energy behavior.
For those who want more, there is an optional pro subscription, but most functions are simply available for free. The app works quickly, synchronizes with the hardware and is actually fun to use for lovers of numbers and statistics.
Practical performance
With a capacity of 2.7 kWh, the battery is ideal for smaller households or for the evening and at night. An average household uses between 2 and 5 kWh at night, so with one battery you can go a long way. Those who need more can scale.
An important comment: the plug-in battery is not an emergency power supply. In the event of a power failure, the battery also switches itself off, purely for safety reasons. The system also does not (yet) support dynamic energy rates or delayed loading – features that may be desirable for some users, but according to HomeWizard do not benefit much for the time being.
Price, payback time and availability
The suggested retail price for one battery is 1395 euros. Add the P1 meter and you are just below 1450 euros. According to HomeWizard you earn the investment in about six years ago. Anyway: we now know that there can change in the meantime. The fact remains that the price is relatively low compared to other home batteries, which means that the threshold for stepping in is quite low.
Then a downside: the popularity. The delivery times have risen to months – but that is also the best compliment that a product can get.
Conclusion: HomeWizard Plug-in Battery
The HomeWizard Plug-in Battery is an accessible, well-thought-out solution for anyone who wants more control over his solar power. Thanks to the plug-and-play character, the smart software and the affordable entry price, this is one of the most accessible home batteries on the market. Those who have finished the return circus and prefer to keep their energy in-house will find a smart solution in the plug-in battery.
