Gain transparency into BESS warranties

Performance warranties are vital for the bankability of energy storage systems. But how do you find the balance between a profitable operating strategy and degradation within the boundaries specified in the warranty?


  • Tracking compliance with complex warranty conditions involves considerable manual effort, but not tracking at all creates significant financial risks.
  • Warranty conditions can differ for every different type of battery, creating a substantial amount of complexity in tracking warranties.
  • Warranty coverage is at risk when the operating strategy is changed.


With the TWAICE warranty tracker, you get a full, up-to-date view of warranty conditions across your battery energy storage systems independent of suppliers. Lower your technical risk exposure, avoid warranty penalties, and improve your workflows to save on costs.

  • Reduce warranty violation risks and penalties by automatically tracking the warranty status of each battery system.
  • Minimize business case risks by adapting operating strategies to reduce your exposure to warranty risks and avoid unplanned warranty de-ratings.
  • For system integrators: use warranty tracking to consider providing flexible warranties to your customers.
