HomeWizard home battery: price and review
Using a HomeWizard battery allows you to store excess solar energy for later use, significantly reducing your electricity bills and your dependency on the grid. This plug-in home battery can be installed easily via a standard socket, and you can expand its capacity modularly up to 10.8 kWh.
In this guide, you will learn how the HomeWizard battery operates, its pricing, when it is the best choice, and its potential limitations, helping you make an informed decision before purchasing through platforms like Soleva.
How exactly does a HomeWizard battery work?
The HomeWizard battery stores extra electricity generated by your solar panels and releases it when needed, using a built-in micro-inverter with a power output of up to 800 W per unit. It connects directly to your home through a standard socket and interacts with a P1 meter to monitor electricity consumption and injection in real time.
How does the Plug-In Battery store and deliver energy?
The battery system utilizes lithium iron phosphate (LiFePO4) cells, which are known for their stability and safety in energy storage. It charges whenever your solar panels produce more electricity than your household consumes. Conversely, it discharges when your home’s energy demand exceeds what your solar panels provide.
The charging and discharging cycle works as follows:
- The P1 meter detects solar surplus energy;
- The battery charges up to 2.7 kWh per unit;
- Energy is stored with an efficiency between 70% and 80%;
- The battery provides power later at up to 800 W;

How does the built-in micro-inverter improve energy efficiency?
The integrated micro-inverter operates efficiently even at low loads, unlike traditional large inverters that often lose energy when demand is low. This design improves efficiency by up to 30% during typical household consumption patterns.
Is HomeWizard Plug-In Battery compatible with Home Assistant?
Yes, the HomeWizard Plug-In Battery supports integration with Home Assistant via a local API. This allows you to monitor battery data and automate charging based on factors such as energy prices or solar generation.
What is the price of a HomeWizard battery?
The cost of a HomeWizard battery starts at approximately €1195 to €1345 including VAT per unit, depending on current offers and bundled packages. This price covers software, updates, and delivery but does not include the P1 meter.
Price overview for different configurations
Typical pricing per setup is as follows:
- 1 battery (2.7 kWh): €1195 - €1345;
- 2 batteries (5.4 kWh): €2390 - €2690;
- 3 batteries (8.1 kWh): €3585 - €4035;
- 4 batteries (10.8 kWh): €4780 - €5380;
Calculation example for an average household
A typical system with two batteries includes these approximate costs:
- 2 batteries: 2 × €1195 = €2390;
- P1 meter: €25;
- Optional display: €60;
- Installation: €0 due to the plug-in design;
The total investment is about €2475 including VAT.

How does HomeWizard battery replacement work?
Replacement is managed via a swap service. Defective units are replaced within the first 7 years or 4000 cycles. After the warranty period, a service fee applies, keeping replacement costs predictable compared to traditional repairs.
When does choosing a HomeWizard battery make the most sense?
This battery is ideal for households that generate solar surplus and have moderate nighttime electricity consumption.
Which households benefit most from a HomeWizard battery?
- Homes with an annual solar surplus between 500 and 3000 kWh;
- Nighttime consumption generally below 800 W;
- Residences equipped with digital meters and capacity-based tariffs;
Learn how capacity tariffs influence savings at capacity tariff impact.
How does the battery perform with electric vehicles and heat pumps?
The HomeWizard battery is suited for base loads but may struggle with high-demand appliances. Devices like EV chargers and heat pumps usually exceed the 800 W limit, meaning your grid will provide additional power support.
What are the test results of the HomeWizard Plug-In Battery?
Tests show the battery achieves a real efficiency of about 75%, with savings varying based on usage patterns. Your daily savings depend on how often the battery cycles and the amount of solar surplus generated.

Frequently Asked Questions
What is the HomeWizard battery price for a full setup?
The total price depends on the number of batteries you choose. A typical two-unit configuration usually costs between €2400 and €2700 including VAT. Additional accessories like a P1 meter or a display add minor costs. Installation costs are avoided because of the plug-and-play design.
Is investing in a HomeWizard battery financially worthwhile?
The battery becomes cost-effective if your household generates significant solar surplus and electricity prices are high. Many users see a return on investment within 4 to 7 years, depending on consumption patterns, tariffs, and how much stored energy replaces grid electricity.
What is the lifespan of a HomeWizard battery?
The battery can last up to 15 years or about 6000 charge cycles. Over time, capacity decreases gradually to roughly 70%. Real-world factors like daily cycling and environmental conditions affect degradation, but the LiFePO4 cells maintain stable performance for long periods.
Can the HomeWizard battery provide power during electricity outages?
No. For safety reasons, the system shuts down automatically during grid outages to prevent back-feeding electricity to the grid and protect maintenance crews. Therefore, it does not serve as a backup power source.
How many HomeWizard batteries should I install?
The number depends on your annual energy consumption and solar production levels. A single battery suits smaller households, while two to four units are recommended for larger households or installations with high solar surplus to maximize self-consumption.
