Stromtank S1000 Battery Power Unit


Run all or part of your system off a computer controlled lithium-iron-phosphate battery array for perfect power structure but no nasties. All audio components connected to STROMTANK are supplied solely by the mechanically isolated, off-grid batteries at a 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 you do get:

  • fully off-grid, pure and consistent sine wave AC at 230V and 50z. 
  • ultra long life design (under heavy use 10 years to 80% battery capacity and cost effective battery replacements if the time comes)

What you don't get:

  • current fluctuations (affecting amp draw an stressing components).
  • DC on the AC (causing transformer hum).
  • AC-line–induced noise generated by computers, appliances, internet, cell towers or LEDs (which increase noise floor).
  • damaging long-term over or under voltage.
  • damaging short-term voltages (surges).


  • 8x individual Lithium Iron Phosphate batteries
