Stromtank S-4000 MK II High Capacity Power Generator

Stromtank S-4000 MK II High Capacity Power Generator

One of the most important aspects to consider if you want to extract the excellent quality of your audio components is the purity and stability of the power grid signal.

The Stromtank S-4000 supplies a perfect and very precise sine wave. Equipped with dual high-performance inverters, fed by a bank of computerized lithium iron phosphate batteries it can deliver instant current when your components demand it.

Bridging the gap between the models designed for source components and the bigger models designed to handle large demanding systems, the S 4000 is capable of driving both the sources and the power amplifiers.

Pure, perfect power at all times to make pure, perfect music!

Time to make the best of what you already own

Stromtank is a high-tech device which will play a central role in hearing the excellent quality of your sound components. Stromtank has been designed to separate your hifi-system completely from the grid to supply clean, undisturbed power to achieve the next level of music quality with your hifi-system.

Most people think that because everything turns on and works, the AC grid is providing an ideal signal. It should be a pure sine wave, with no distortion, no high frequencies harmonics, and stable in frequency and amplitude. Unfortunately, this is mostly not the case. Everyone is connected to the same dirty grid, polluted with DC voltage and frequencies. All interferences manipulate audio and video quality and even the best power conditioners are not able to eliminate all disturbances.

After extensive research on various ways to improve the quality of the network, Stromtank opted for a radically different approach. Their goal is to make you completely independent from the traditional, fluctuating domestic power grid. Regardless of what happens with the electricity, your system is always unaffected. The Stromtank power generator offers you the unique opportunity to provide your system with stable energy, completely disconnected from the electrical grid.

Inverter

The Stromtank is equipped with a high-performance inverter, which supplies a perfect and very precise sine wave.  The Stromtank is protected against overloads and short-circuits.

Thanks to the largely over-dimensioned performance level, loads up to three times higher than the Stromtank’s rated power can be faultlessly supplied for short periods of use, thus allowing the load to be started up without any problem.

The perfect addition for your audio-setup

During the recharging process you can listen without any interruption. Even when the Stromtank is connected to the grid, the current pulses are not taken directly from the grid - they are absorbed by the battery. In the AC-connected mode the Stromtank creates a stable AC-supply (amplitude and frequency) and has less interaction between the grid and your audio or AV setup.

With the Stromtank, the quality of premium home theatre equipment is both visually and sonically enhanced.
