The key feature is its **stackable modular structure** - capacity increases with each additional segment, and installation can be either floor-mounted or wall-mounted, even in spaces with limited room. The applied chemistry, **LFP (lithium iron phosphate)**, supports thermal safety and stable performance during frequent cycling, which is crucial for photovoltaic self-consumption and dynamic tariff charging. For the user, the combination of **high cycle durability** and **long warranty** is essential - in practice, this means years of intensive energy storage without concerns about rapid capacity degradation. The system is **compatible with hybrid inverters from SMA**, facilitating integration into grid-connected systems with backup power options. This solution is tailored for homes and small businesses - where scalability, predictable longevity, and a cohesive energy management ecosystem matter. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/batteries/7f1eba6e74c0de5354bbe08ebff30be8650629ca_Karta_Katalogowa-40dc4db83936.pdf) ## Alternatives | Battery | Usable energy | Round-trip | Power | Voltage | Difference | | --- | --- | --- | --- | --- | --- | | [Pylontech Force H1 (3 modules)](https://comparepv.com/battery/pylontech-force-h1-3-modules) | 6.39 kWh | | | HV | -0.2 kWh | | [Pylontech Force H2 (2 modules)](https://comparepv.com/battery/pylontech-force-h2-2-modules) | 6.39 kWh | | | HV | -0.2 kWh | | [Solplanet Ai-HB 075A](https://comparepv.com/battery/solplanet-ai-hb-075a) | 6.91 kWh | 95.0% | 4.6 kW | HV | +0.4 kWh, +0.5 pp round-trip, -2.3 kW | | [Dyness Tower T7](https://comparepv.com/battery/dyness-tower-t7) | 7.1 kWh | | 4.3 kW | HV | +0.5 kWh, -2.7 kW | | [FoxESS HS7.5](https://comparepv.com/battery/foxess-hs7-5) | 7.15 kWh | | | HV | +0.6 kWh | | [Dyness Tower Pro TP7](https://comparepv.com/battery/dyness-tower-pro-tp7) | 7.3 kWh | 95.0% | 7.7 kW | HV | +0.7 kWh, +0.5 pp round-trip, +0.8 kW | | [Deye GB-L8](https://comparepv.com/battery/gb-l8) | 7.36 kWh | | 8.2 kW | HV | +0.8 kWh, +1.3 kW | | [Deye GB-SL-EU (2 modules in series)](https://comparepv.com/battery/gb-sl-eu-2-modules-in-series) | 7.36 kWh | | | HV | +0.8 kWh | --- Source: https://comparepv.com/battery/sma-solar-technology-ag-sma-home-storage-6-5
