11 Storage system expansion
The capacity and the charging and discharging power of TESVOLT battery systems can be expanded.
11.1 Capacity expansion using the TESVOLT battery storage system
New battery modules are delivered with a state of charge (SoC) of 20%. In order to integrate a new battery module into an
existing battery system, the existing system must also be brought to a state of charge of 20%. Only then the new battery
modules can be installed in the existing system and put into operation. When the system is restarted, the APU will call up on the
display the number of modules now recognized. If this is correct, confirm by tapping the display twice. The battery’s new
capacity must also be updated in the Sunny Islands. To do this, run the Sunny Island QCG and enter the updated capacity (Ah).
