For municipalities and fire services
Stay operational when the power goes.
A siren test checks the siren. It does not check whether the fire station still has light afterwards, whether the radios keep charging, or whether the municipal office stays reachable. That is what we build storage for.
01 The occasion
On 3 October the sirens sound.
Austria’s nationwide civil protection siren test checks a single link in the chain: whether the warning signal arrives. What happens afterwards is not tested — and that is exactly where the gap sits.
The Austrian Civil Protection Association advises households to prepare for ten to fourteen days. 87 per cent of Austrians, by contrast, expect power to return within 24 hours. The time between that expectation and that recommendation is the time a municipality, too, has to bridge on its own.

02 What happens
The first seconds decide.
Storage only helps if it is there before anyone notices it is missing. So what counts is not what it can do, but when it does it.
Second 0
The grid fails.
Lighting, radio, doors, servers, cooling — all at once.
typically 20 ms
Storage takes over.
Short enough for most equipment. The datasheet figure is typically 20 milliseconds, 80 in the worst case — for servers we additionally recommend a UPS.
Hour 1 to 12
Operations continue.
Command post, lighting, door systems, chargers, communication. How long depends on what is connected — we work that through together during the site review.
Day 1 to 14
Recharge rather than give up.
Rooftop photovoltaics recharge the storage during the day. An existing generator can be integrated and starts by itself once the state of charge drops below a set threshold.
03 The figures
Proven, not claimed.
Every figure comes from the datasheet and is open to you before the decision — not only after it.
Transfer time on grid failure
Datasheet figure typical, 80 ms maximum.
Installed → usable
Usable even after ten years.
Usable when expanded
Expandable pack by pack, up to three units in the standard build.
Power per inverter system
Two sizes, operable in parallel.
Cell chemistry
Cobalt-free, passively cooled, all-metal enclosure.
Engineering
Engineered in Böheimkirchen, Lower Austria.
04 Where
Four places where the power must not fail.
Fire service
The fire station.
Command post, radio, door systems and chargers stay in operation. Whoever is needed during a blackout must not become a case themselves.
Administration
The municipal office.
Telephony, network and registry keep running. The municipality stays reachable for its residents even when nothing else works.
Utilities
Water and wastewater.
Pumps and controls in the reservoir or treatment plant need power around the clock. A failure here becomes visible within hours.
Shelter
School, gym, emergency shelter.
Wherever people are housed, you need light, heat and sockets. Storage turns a building into a place people can go.
05 The timing
The 2027 budget is adopted in autumn.
Investment in security of supply belongs in the budget, not in a supplementary budget after the first incident. Which subsidies apply in your case is something we look at with you and substantiate before counting on it.
Let us talk about your site.
In the site review we go through what has to keep running, for how long, and what that means in terms of storage. Free of charge and without obligation.
