“The Stromtank S-2500 Quantum MKII is a revolutionary, battery-powered power regenerator and conditioner designed to unlock the ultimate performance of high-end audio and video systems. Unlike conventional power solutions, the S-2500 Quantum MKII completely isolates your components from the fluctuating, noisy mains grid, supplying pure, regenerated sine wave AC power directly from its advanced 2,100 Wh LiFePO4 battery array when in “”off-grid”” mode.

This flagship unit eliminates all forms of mains contamination – including noise, voltage swings, and DC offset – resulting in an audibly lower noise floor, enhanced dynamics, pristine clarity, and a wider, more stable soundstage. The MKII benefits from an upgraded 48V battery system, delivering higher continuous (650 VA) and peak (2600 VA) power, along with improved battery management and digital distortion suppression. With up to 4 hours of pure battery operation (and automatic seamless transfer), the 61 kg Stromtank S-2500 Quantum MKII acts as a dedicated, silent power plant for your system, allowing every component to perform at its absolute best.”

Stromtank is not a traditional conditioner or a simple filter, Stromtanks create their own perfect AC waveform and when in green operating mode, are completely disconnected from the AC grid.

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.

Stromtank offers unique opportunity to provide audio 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 the system from any AC surges, sags, noise, or radiations.

What’s inside

The heart of all the Stromtank units is the innovative battery technology known as lithium iron phosphate (LFP). Stromtank uses a special type of LFP battery that offers maximum power delivery, extended battery life, voltage stability, and intrinsic safety. The lifetime of Stromtank batteries is ensured by a battery management system that was specially developed in conjunction with the Fraunhofer Institute in Nuremberg, Germany – experts in efficient battery management technologies.

Each individual cell provides feedback to the active battery management system. This intelligent system has three major functions:

- Active balancing of all cells in the array to maximize efficiency of discharging and charging cycles.
- Inspection of temperature, voltage, current load and state-of-charge of each single cell
- By monitoring and managing the battery array, the system is completely maintenance free

Digital Distortion Suppression
Eliminating digital and backwards interference from other audio components.

12V Trigger
12V trigger and network control make Stromtank models easy to integrate into any installation appliication.
