Changing The Battery Usage Through Battery-Backup Systems With Increased Self-Consumption - SMA SUNNY ISLAND 3.0M Installation Manual

8 Commissioning
Procedure:
1. Log in to the communication product as Installer (see the user manual of the communication product) or switch to
expert mode on the Sunny Remote Control (see the Sunny Island operating manual).
2. Set the following parameters for the battery usage:
Parameter
Increased self-consumption switched on / 261.01 SlfCsmpIncEna Enable
Lower limit of the deep-discharge protection range before
disconnection / 262.01 ProtResSOC
Minimum width of the deep-discharge protection range /
262.02 BatResSOC
Width of the range for the maintenance of the battery state of
charge / 262.04 PVResSOC
Minimum width of the self-consumption range /
262.05 MinSlfCsmpSOC
Highest yielding month for battery utilization range /
261.02 SlfCsmpPosSel
Seasonal operation active / 261.03 Saisonenable
* Set the value to North when June is the month with the highest yield.
** Set the value to South when December is the month with the highest yield.
✖ A parameter cannot be adjusted?
All ranges combined result in a value greater than 100%.
• Ensure that all ranges have been set correctly.
8.2.4.3 Changing the Battery Usage through Battery-Backup Systems with
Increased Self-Consumption
Adjusting the default values
The parameters for battery usage are set automatically to reasonable values during basic configuration for the
respective system. The parameter values can be adjusted if there are special requirements for the system or the
battery.
Two ranges can be adjusted seasonally in battery-backup systems with increased self-consumption:
• Range for increased self-consumption (MinSlfCsmp)
You determine the percentage of the battery capacity that is to be used for increased self-consumption on the shortest
day of the year.
• Range for battery-backup function (BURes)
You specify the percentage of the battery capacity that is to be used for the battery-backup function on the longest
day.
The longer the days become, the more the SlfCsmp range automatically increases and the BURes range decreases.
The range for increased self-consumption reaches its maximum on the longest day:
SlfCsmp = 100% − 262.04 PVResSOC − 262.03 BUResSOC − 262.02 BatResSOC − 262.01 ProtResSOC
