Adjusting system voltage with SMA SB Storage
To add Helios battery modules, the system voltage must be adjusted to the module
voltage. For this purpose set the Sunny Boy Storage to a specific SOC:
1.
Open the Sunny Boy Storage user interface.
2.
Register as installer.
3.
Select
Device Parameters
and click on
Edit Parameters
.
4.
Enter the required SOC at
Battery - External Default
and confirm at the top
of the Web UI with
Save All
.
Example:
The new battery module has 50.7 V
–
equals approx. 35 % SOC.
Hyperion has 60 % SOC
–
set
Lower battery discharge limit
to 35 %
and confirm with
Save all
.
5.
The battery system adjusts to the parameterized SOC and holds it.
6.
Install the new battery module. See chapter 3.3.4 from step 3.
