Stromtank S-2500 Quantum MkII Power Generator
Can you call it “the new middle class”? In a way, yes, but only within our device hierarchy. Otherwise, the S2500-Quantum is absolutely top class. This model embodies our uncompromising approach, featuring a high-performance balancer for unique charging control, ensuring ideal battery performance and longevity at all times.
For those who enjoy a diverse range of music and don’t use excessively large power amplifiers, the S2500-Quantum is perfect. Notably, it is the first StromTank in the model range with 16 LFP batteries (48V System), offering greater thrust in the lower mids and an extended low frequency.
Alternatively, the S2500-Quantum can power a smaller stereo system, one where an S1000-SourcePower would normally suffice, eliminating the need for power upgrades for a long time.
Dreams come true – with your own real GENERATOR
After extensive research on various ways to improve the quality of the network, we opted for a radically different approach.
We take care making you completely independent from the traditional, fluctuating domestic power grid, by developing your own, independent power plant to supply your audio components.
This power generator is called STROMTANK.
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 it may be perfect for you during this time no matter how many power plants are on and off be turned off and how many hair dryers and PowerLAN adapters in the Neighborhood mischief.
The main feature of each STROMTANK is a powerful generator combined with a high capacity battery and a unique feature.
Each Stromtank model has 2 different working modes:
- ON-grid (blue illumination at front meter)
STROMTANK supplies the audio system from the electrical grid according to the principle of a regenerator, but with one important difference:
an insufficient power supply will be compensated by a block of rechargeable batteries, which thanks to an permanent controlling of the system is able to supply as much energy as required (boost-function)
- OFF-grid (green illumination at front meter)
All audio components connected to STROMTANK are supplied solely by the batteries with constant current. The average autonomous operating time 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 critical minimum, the STROMTANK will automatically recharge itself from the mains.
What exactly is it?
This development was possible by using the new and innovative battery technology: lithium iron phosphate (LFP).
STROMTANK uses a special type of LFP battery that shines with maximum power delivery, maximum lifetime, voltage stability and intrinsic safety.
Another essential point is the lifetime of STROMTANK’s LFP batteries. This is ensured by our battery management system specially developed for these needs.
Decisive for the long life cycle of a battery is the professional treatment of each individual cell with an intelligent, active battery management system. His priority tasks are:
- Active balancing up to 10A bi-directional (charching & discharging)
- Inspection of temperature, voltage, current load and state-of-charge of each single cell
- absolutly maintenance free
SROMTANK mastered this challenge together with the Fraunhofer Institute Nuremberg – the specialist for efficient battery management technologies.
This mature and proven technology stands for engineering “Made in Germany”.
