The Stromtank offers the unique possibility to separate your hifi-system completely from the grid.
AC power anomalies refer to deviations from normal power supply conditions that can affect the performance of electrical equipment - high-end audio, video production studios, computer networks, industrial equipment. Some examples of AC power anomalies include:
- Voltage sags: a temporary decrease in voltage level.
- Voltage swells: a temporary increase in voltage level.
- Voltage dips: a temporary decrease in voltage level that lasts for a longer duration than a sag.
- Voltage spikes: a temporary increase in voltage level that lasts for a shorter duration than a swell.
- Voltage transients: a sudden, brief voltage deviation from the normal level.
- Voltage interruptions: a complete loss of power for a short period of time.
- Harmonic distortion: a deviation from a pure sine wave form that can affect the performance of electronic equipment.
These power anomalies can cause equipment damage or malfunction, and can also reduce the efficiency of equipment over time. Power conditioners can be used to help mitigate the effects of these anomalies by filtering out unwanted noise, regulating voltage levels, and protecting equipment from damage.
For years, there have been many devices that use a variety of techniques to address AC power anomalies. The Stromtank models take this a step further and instead of simply adding a filter to the AC power signal, a Stromtank creates its own AC power! A Stromtank is completely independent from the traditional, fluctuating domestic power grid, by developing its own, independent power plant to supply your audio components.
Only the power generator Stromtank offers you the unique opportunity to provide your system with stable energy, completely disconnected from the electrical grid. This complete network separation works for hours and is electrically disconnected from the AC main circuits isolating your system from any AC surges, sags, noise, or radiations.

S-1000
Everything that characterises the StromTanks can already be found in our smallest model. Depending on the system configuration, even with the S-1000 there are no limits to absolute music enjoyment.

S-2500 Quantum MK-II
The new middle class“, if you go by our device hierarchy. Otherwise, the S-2500 Quantum MK-II is, of course, absolute top class. Here, too, we have implemented everything in line with our uncompromising approach.

S-4000 ProPower MK-II
The S-4000 ProPower not only cuts a fine figure in many recording studios. It is also a classic power tank, but one with eight LFP batteries and two inverters.

S-5000 HighPower MK-II
Many people say that life is made up of compromises. We say it consists of decisions. And if you have opted for a high-end system, then you also want to be able to call up its optimum performance at all times.


S-1000
Everything that distinguishes the StromTanks can already be found in our smallest model: a mains-independent generated perfect sine wave for the best sound. Whereby „small“ should not be considered underpowered, because the entry into the StromTank world can also be the perfect choice for many. Depending on the system configuration and listening habits, there are no limits to absolute music enjoyment with the S1000-SourcePower.
S-2500 Quantum MK-II
Can you call it “the new middle class”? In a way, yes, but only if you orientate yourself within our device hierarchy. Otherwise, the S2500-Quantum is of course absolutely top class. In this model, too, we have implemented everything in line with our uncompromising approach. The so-called high performance balancer provides this unique charging control, ensuring both ideal battery performance and battery life at all times.
S-4000 ProPower MK-II
Technically, the S4000-ProPower occupies a special position because it marks the transition to the ultra-high-end range and thus also cuts a good figure in many recording studios. It is likewise a classic StromTank, and now in its latest version also one with 16 LFP-batteries (48 Vdc system) and two inverters. These inverters are responsible for limiting the power draw. The maximum current of the DC/AC converter must be taken into account, as well as the heat generated during conversion.
S-5000 HighPower MK-II
Life consists of compromises, many say. We say it’s made up of choices. And if you have chosen a high-end system, you also want to be able to call up its optimum performance at any time. That’s why our top model, with its truly gigantic power reserves, has a very simple mission: to stand by the best systems.NEW: Audio Distribution Bar

Operation
Full Battery Mode - Meter illumination is green
All audio components connected to Stromtank are supplied solely by the batteries with constant current. The average operating time in full battery mode is 4-8 hours, depending on the choice of Stromtank model and the energy consumption of the connected components. When the battery state-of-charge reaches a pre-determined minimum, the Stromtank will automatically reconnect to the AC power and recharge itself. Listening is uninterrupted and the unit will enter AC Grid mode.
AC Grid Mode – Meter illumination is blue
In AC Grid Mode, recharging occurs and listening may continue without any without disruption. When the Stromtank is connected to the AC power grid, much of the Stromtank benefits are still realized. The AC current delivered to the system is still not taken directly from the AC line but instead is absorbed by the battery. In the AC Grid mode, the Stromtank still creates a perfect AC waveform, both amplitude and frequency. This unique operation provides less interaction between the AC power line your audio video system.
