Tesvolt Li

 




The versatile TESVOLT Li storage cabinet series uses TESVOLT's unique active bidirectional transmissiontional battery management system (BMS) allowing for increased modularity and efficiency. Because of the special control, the cells are optimally charged and discharged to ensure a long shelf life.

  • For solar, wind, hydropower, biogas plants and CHP plants
  • Active bidirectional battery management
  • 10 year performance warranty
  • Real battery back-up system (900 A)
  • Peak load capping
  • On- and off-grid
  • Stand-alone grid function
  • Zero feed-in

Customised charging speeds
You decide how fast your storage system charges! Select the quantity of charge controllers and their output
according to the capacity of your storage system and desired charging speed.

Long service life
The specifically developed battery management system guarantees the optimal battery cell charging and discharging rate, and makes the storage system particularly durable. TESVOLT guarantees a 10 year performance warranty on all storage systems.
Recyclable
Batteries can be returned to TESVOLT for free.
Transparent
Each individual cell stack is monitored and controlled online. This simplifies maintenance and ensures maximum transparency.
Twice as safe
Our lithium-iron-manganese-phosphate battery cells are among the safest on the market. The cells are prevented from overheating or overloading by a battery management system and temperature sensors.
 Environmentally friendly
TESVOLT batteries do not contain environmentally-harmful heavy metals.
