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.

  1. Set the correct battery type as well as the correct values for nominal voltage and battery capacity when configuring.
  2. 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).

Parameter names and units depend on the inverter's firmware version.

The parameter names and units depend on the inverter's firmware version. Parameter names and units of inverters with a firmware version ≤ 2.99.99.R differ from those of inverters with a firmware version ≥ 3.00.00.R.

Setting of parameters in single-cluster and multicluster systems

In single-cluster systems, the master captures all user input. The slaves follow the specifications of the master.

In multicluster systems, the master of the main cluster captures all user input and sends it to the master of the extension clusters. The slaves in all clusters follow the specifications of the respective master.

Requirements:

  • The personal SMA Grid Guard code of the Installer must be available for the changing of grid-relevant settings after completion of the first 10 operating hours or of the installation assistant. You can request the SMA Grid Guard code via the Online Service Center.

Procedure:

  1. Open the user interface Establishing a connection to the user interface).
  2. Log into the user interface Logging In and Out of the User Interface).
  3. Call up the menu Device parameters.
  4. Click on [Edit parameters].
  5. Log in using the SMA Grid Guard code to change those parameters designated by a lock (only for installers):
  6. Expand the parameter group that contains the parameter which is to be configured.
  7. Change the required parameters.
  8. Select [Save all] to save the changes.
  • The inverter parameters are set.
