Bring the battery modules to a state of charge of 30%

Exception for battery systems with STPx.0-3SE-40

Battery systems with STPx.0-3SE-40 require at least 2 operational battery modules for commissioning. Only for battery systems with STPx.0-3SE-40, the following measure applies:

  1. If, after disassembling the defective battery modules, only one battery module remains in the battery system, continue directly with assembling and connecting the new battery module.

Requirement:

  • Removing the defective battery module is complete.

Procedure:

  1. Recommission the system with the remaining battery modules.
  2. Bring all remaining battery modules to a state of charge of 30%. To do this, determine the current state of charge via the user interface of the inverter and charge or discharge the battery depending on the current state of charge.
  3. Disconnect the battery modules from voltage sources again ( > Disconnecting the battery modules from voltage sources).
