- Revolta's datasheet describes this 450 V home battery as built on lithium-free, cobalt-free sodium-ion cells with each cell controlled individually, and its June 2026 release describes a voltage multiplier architecture using a high-frequency transformer.
- Revolta's website says the product is available from September and takes reservations through a waitlist, so this page treats it as announced rather than shipping.
- The only datasheet is marked preliminary (V0.11, September 2026) and gives no warranty terms, no cycle life and no system round-trip efficiency, only a module efficiency above 95 per cent, so it cannot be scored yet.
- Capacity figures differ across Revolta's own sources: the datasheet gives 2.0 kWh modules but a 2.0-22 kWh system, the product page gives 2.0 to 20 kWh, and the June release gives 2.2 kWh modules up to 22 kWh.
- The datasheet prints the module code as HV-2.0 NA while the product page prints HV-2.0 Na; both are shown here as printed and this record is not joined to any scored battery.
- Legal manufacturer as printed: Revolta AG, Oeserstr. 31c, 65934 Frankfurt a.M., Germany.

Establishes that the product page prints the code as HV-2.0 Na and gives 2.0 kWh modules scaling to 20 kWh with one to ten modules.
- Revolta, homepagehttps://revolta.tech/
Establishes the maker's stated market status: available from September, with modules reserved through a waitlist.
- Revolta AG press release via news aktuell, 19 June 2026https://www.presseportal.de/pm/182833/6297584
Establishes the voltage multiplier architecture with a high-frequency transformer, the Intersolar Europe 2026 launch, and the 2.2 kWh module and 22 kWh system figures given at announcement.
