More energy at the right time – thanks to smart storage
Your solar panels generate a lot of power, especially around midday – often more than you use directly at home. That's precisely where the SAX Power battery offers the solution: it safely stores surplus solar energy and delivers it back to you when you really need it – in the morning at the start of the day or in the evening after work.
This allows you to easily handle peak consumption and significantly reduce your dependence on the electricity grid. The innovative technology of the SAX Power battery also ensures maximum efficiency, safety, and a long lifespan.
The result: your solar energy isn't wasted, but supports you precisely when your energy needs are greatest – for greater independence, cost savings, and sustainability.
For subsequent installation – easy integration, without additional equipment
The SAX Power Home doesn't require a separate inverter on the battery side. This means a particularly clean, space-saving, and hassle-free solution for you. Existing solar systems can be expanded without major modifications – saving you money, time, and unnecessary additional components.
This not only makes retrofitting easier, but also future-proof: your existing PV system works efficiently with the SAX Power battery, without additional interfaces or complex installations.
For new construction – smart planning, saving from the start
The SAX Power System operates without an inverter on the battery side. This eliminates the need for an expensive hybrid inverter in a new installation. This not only reduces investment costs but also saves space in your system setup.
With SAX you choose a system that is designed efficiently and future-proof from the start – fewer parts, less complexity, more reliability.
For battery extensions
It SAX Power System uses a special balancing method that optimally balances the charge status of the cells. Weaker cells therefore have virtually no impact on the performance of the entire battery. With subsequent upgrades, the advantage of the SAX Power circuit becomes particularly clear: the new battery modules deliver their full power and are not negatively affected by the older cells.
With a SAX Power battery, you can make your home independent of rising energy costs. Once installed, it provides you with clean power day and night, ensuring your energy supply is secure. This lays the foundation for a sustainable future – right in your own home.
And the best part is: you can safely forget about technology. The SAX battery works quietly, efficiently, and reliably in the background – while you enjoy life carefree. Less dependency, more freedom, and the good feeling of doing something good for the environment at the same time.
