Figure 3: Nameplate and safety instructions on the battery stack
Note:
The battery system should be operated only with approved battery inverters / battery chargers.
The nominal battery voltage is 51.2 V, and communication between the battery inverter / battery
charger and the battery system takes place via a data interface (CANOpen).

Hints for sizing of the system
The battery system communicates with the battery inverter and therefore realizes an
automatic system operation. It is not required to operate the system manually. However for
system sizing and operation the following hints shall be observed:
Note:
Sizing of the entire system including installed PV and inverter power and the operation scheme of
the system (electrical loads) must realize occasional battery full charges (state of charge
– SOC
= 100%).
Note:
Sizing of the entire system shall consider the usage of 80% to 90% of the nominal battery
capacity.
