As energy prices continue to fluctuate worldwide, more and more households in the Netherlands and Belgium are considering purchasing a home battery. Such a system works optimally in combination with solar panels: electricity generated during the day that you would otherwise supply for little money is stored for use in the evening. In addition, you benefit from peak-off-peak optimization and you always have an emergency supply in the event of a power outage. But which system suits your situation best? In this extensive comparison we put three popular home batteries side by side, so that you can make an informed choice.
Anker SOLIX Solarbank Max AC: efficient home battery for solar panel users
Target group: specially designed for solar panel owners
The Anker SOLIX Solarbank Max AC has been specifically developed for households that have already installed solar panels. The system solves a common problem: during the day you produce more electricity than you consume, while in the evening - especially during peak hours - you have to rely on more expensive mains electricity. The Solarbank Max AC stores excess solar energy for later use and at the same time provides a reliable emergency power supply. Ideal for families who generate a lot during the day but consume a lot in the evening, who want to use dynamic or peak-off-peak rates, or who want to expand their installation in the future.
Flexible storage and high power: suitable for various consumption profiles
The basic storage capacity is 7 kWh — precisely matched to the average evening consumption of a Dutch household (6–8 kWh). You can increase the total capacity to a maximum of 42 kWh via expansion batteries, and even up to 126 kWh by connecting three systems in parallel. The 3.5 kW AC input and output power can fully accommodate the peak power of most residential solar panel systems (3,000–4,000 W), ensuring no self-generated energy is lost. In addition, the system supports high-powered appliances such as washing machines, dishwashers and charging stations for electric vehicles. The built-in off-grid output socket delivers 3,680W and switches to UPS mode within 10 milliseconds in the event of a power outage, keeping your refrigerator, router and other essential appliances running uninterrupted.
Smart energy management: AI-driven cost optimization
The system is equipped with the Anker Intelligence AI platform, which combines historical production and consumption data with current weather forecasts and dynamic energy rates. Based on this, the system predicts the energy demand and supply for the next 24 hours and automatically optimizes the charging and discharging strategy: automatic charging during off-peak hours or periods with negative electricity prices, and prioritizing stored energy during the most expensive peak hours. The accompanying Anka voice assistant offers real-time ROI calculations, weather analyzes and notifications of production losses, so that you always have insight into your energy yield. Thanks to a 100% depth of discharge (DoD) and the ability to complete two full charge cycles per day, you utilize the battery's full storage capacity.
Reliability and durability: designed for years of use
The cells have a lifespan of 10,000 charge cycles, with a design life of 15 years and a 10-year warranty — one of the longest in its class. The system is protected to IP66 and certified for corrosion resistance at level C5-M. The operating temperature range is from -20°C to +55°C, and an active heating system ensures that the battery remains fully functional even in harsh Dutch winters. Suitable for both indoor and outdoor installation (avoid immersion and extreme corrosive environments).
Easy installation and local certification: worry-free use
The modular stacking design allows for a simple plug-and-play DIY installation: inserting the main unit or an extension battery only takes about 5 minutes. Supplied Schuko cord allows connection without an electrician; for a higher output power you can also opt for a Wieland plug or fixed cabling. The product is certified and approved in the Netherlands and Belgium; private individuals only need to register their installation via the local grid operator.

Which system suits you best? Choose based on your situation
Choosing a home battery is not a one-size-fits-all decision. Your ideal system depends on your consumption profile, local energy rates and installation environment:
- Do you already have solar panels and do you want high power, smart cost optimization and a long lifespan? The Anker SOLIX Solarbank Max AC offers 7 kWh basic storage, 3.5 kW power, AI-controlled energy management and 10,000 charging cycles. It is ideal for households that generate a lot during the day, consume a lot in the evening or use dynamic rates.
- Do you put safety first and value a strong brand and global service coverage? The BYD Battery-Box offers the highest safety standards with its Blade-LFP technology and extensive global service network, and is suitable for regions with varying grid standards.
- Is installation space limited and do you want high energy density combined with precise energy management? The CATL EnerOne/EnerC delivers more storage per cubic meter thanks to high energy density cells, and the intelligent BMS optimizes your energy consumption in detail. An excellent choice for compact homes or users with business expansion plans.
Would you like to know whether a home battery is financially interesting in your specific situation? Also take the local energy rates into account: a large difference between peak and off-peak rates, high feed-in rates or low feed-in prices make a home battery more attractive. If the peak-off-peak differences are small or the return price is high, carefully consider the payback period. Local subsidies or SDE++ schemes can further strengthen the business case and significantly shorten the payback period.
