The smarter way to
independent energy supply
independent energy supply
A photovoltaic system provides ample electricity – environmentally friendly and cost-effective. However, at midday, when the sun shines brightest, electricity consumption is usually relatively low. The generated electricity cannot be consumed.
The SAX Power battery storage offers the solution for this. It stores the surplus energy from midday and releases it during times of high demand. Thanks to its patented circuitry, the SAX Power battery storage also stands out from conventional batteries and offers:
- High-voltage technology with maximum safety
- High fire protection thanks to a shutdown time of only 0.2 milliseconds in case of error
- Highest efficiency for optimal use of your solar energy
- Environmentally friendly production chains through the use of cobalt-free cells
In this way, your valuable solar power is used cost- and energy-efficiently directly on site.
Maximum Safety
- No fire or explosion hazard
- Use of LiFePO4 cells (Lithium Iron Phosphate)
- 0.2 milliseconds shutdown time in case of error
- 18 volts maximum voltage after shutdown
Easy Installation
- Have Smartmeter or SAX HEMS* installed by a qualified electrician in the meter cabinet
- Hang and connect the storage unit
- Done!

Battery Storage for Retrofitters
The SAX Power Home does not require an inverter on the battery side.
Battery Storage for New Installations
The SAX Power battery storage does not require an inverter on the battery side. Therefore, a new installation does not require an expensive hybrid inverter. This saves costs and installation space.
Battery Storage for Battery Expansions
SAX Power battery storage units feature a special balancing method that optimally equalizes the charge states of the cells. Weaker cells have almost no influence on the overall battery performance. When expanding later, the advantage of the SAX Power battery storage’s circuitry is particularly clear: the new battery modules deliver full performance and are not negatively affected by older cells.
