Removing a detected energy meter from the PV system
If only one energy meter is detected by the inverter, this will be added to the PV system
automatically. Removal via the menu
Device configuration
is not possible in this case. To
remove the energy meter from the PV system, proceed as follows:
• In the parameter group
System communication > Measured values > Meter on
Speedwire
, set the parameter
Serial number
to any number (e.g.
1
). In this way,
instead of the energy meter detected, the PV system will add a fictitious energy meter to
which the inverter cannot establish communication.
Procedure:
1. Activate the user interface (see Section 8.1, page 50).
2. Log in as
Installer
.
3. Start the installation assistant (see Section 8.4, page 59).
4. In the context menu, select [
Starting the installation assistant
].
5. Select [
Save and next
] until you get to the step
Meter configuration
.
6. Add or replace the desired energy meter.
8.15 Setting the heating mode for the battery
The inverter features a heating mode for "Tesla Daily Powerwall" batteries from Tesla Energy. The
heating mode helps conserve the battery at low temperatures. This way, you can increase the
service life of the battery. The heating mode is normally set such that the battery is automatically if
temperatures are too low and enough charging power is available. The heating energy is covered
by excess PV power.
The heating mode should always be activated if the battery is installed on a location where
temperatures below -10°C are expected and, in this case, has to be charged immediately when
excess PV power is available. The heating energy will be drawn from the utility grid.
The heating mode for the battery can be deactivated if the battery is installed on a location where
the temperature does not fall below 10°C.
To modify the default setting of the heating mode for the battery, proceed as described below.
The basic procedure for changing operating parameters is explained in another section (see
Section 8.8 "Changing Operating Parameters", page 62).
Procedure:
1. Select the parameter group
Battery > Operation > Battery
.
2. To activate the heating mode, set the parameter
Heating mode
to
On
.
3. To set the automatic heating mode, set the parameter
Heating mode
to
Automatic
.
4. To deactivate the heating mode, set the parameter
Heating mode
to
Off
.
