Changing Operating Parameters
The operating parameters of the inverter are set to certain values by default. You can change the operating parameters to optimize the performance of the inverter.
This section describes the basic procedure for changing operating parameters. Always change operating parameters as described in this section. Function-sensitive parameters are only visible to qualified persons and can only be changed upon logging in as Installer. These parameters are designated in the user interface with a locked padlock.
NOTICE
Damage to the battery due to incorrect settings
The set battery parameters influence the charging behavior of the inverter. The battery can be damaged by incorrect settings of the battery type, nominal voltage and capacity parameters.
- Set the correct battery type as well as the correct values for nominal voltage and battery capacity when configuring.
- Ensure that the values recommended by the manufacturer are set for the battery (refer to the technical data of the battery in the manufacturer documentation).
Requirements:
The SMA Grid Guard code must be available (see "Application for SMA Grid Guard Code" at www.SMA-Solar.com) for making changes to utility-grid-related parameters.
Procedure:
- Open the user interface ( > Establishing a connection to the user interface).
- Log into the user interface ( > Logging In and Out of the User Interface).
- Call up the menu Device Parameters.
- Click on [Edit parameters].
- Log in using the SMA Grid Guard code to change those parameters designated by a lock (only for installers):
Select the menu User Settings ( > Start Page Design of the User Interface).
In the subsequent context menu, select [SMA Grid Guard login].
Enter the SMA Grid Guard code and select [Login].
- Expand the parameter group that contains the parameter which is to be configured.
- Change the desired parameters.
- Select [Save all] to save the changes.
- The inverter parameters are set.
