6.7.10 Entering the battery capacity/nominal power on the type
plate
Tools:
•
Permanent marker
►
Mark off the correct battery capacity and nominal power on the type plate of
the storage system.
The type plate is located on the outside of the storage system. The battery capacity
and nominal power can be determined from the technical data (see page 14).
6.8 Subsequent battery add-on
Damage to battery modules through high compensation currents!
When the storage system is switched on, diering voltages of the battery modules
can lead to high compensation currents.
►
Charge the storage system to 85% before installing newbattery modules.
►
Measure and note the voltages of the individual battery modules before
installation.
►
Only install battery modules if the maximum deviation between measured
voltages is less than 1 V.
New battery modules come with 85% charge. This is why older battery modules
must also be charged to this level before installing new ones.
