4.3. Settings menu
In the settings menu the the solar charger and MPPT Control settings can be viewed and changed.
Caution
Do not change settings unless you know what they are and what the effect of changing these setting can be. Incorrect settings may cause system problems including damage to batteries. When in doubt, seek advice from and experienced Victron Energy installer, dealer or distributor.
To navigate the settings menu:
Press the SETUP button for 2 seconds to enter the settings menu
The first menu item is shown.
Navigate to the desired menu item by pressing the up and down button.
Once arrived at the desired menu item, press the SELECT button to view the value the setting has been set to.
To modify this setting press the SELECT button again. teh value will now blink.
Press the up or down button to choose the desired value.
Press SELECT to confirm the change, you will hear a beep and will see the word SAVED. The change is made final.
Navigate to the next menu item, or press SETUP to return to the setup menu.
To leave the setting menu, press the SETUP button again.

MPPT Control setting navigation chart
All available settings are indicated in below table, in the order they appear when scrolling trough the menu, together with a basic description of each setting. For the full description of the solar charger settings refer to the solar charger manual.
Not all setting listed in below table might be available when connecting to certain models of solar chargers. The solar charger might not have the necessary hardware. For example, not all solar chargers are equipped with a load output.
Some settings might be missing from the settings menu. The MPPT Control display only allows to change the most common settings. More advance settings, like TX and RX port settings, are not accessible via the MPPT Control display. To configure these settings use the VictronConnect App or, for solar chargers 60A and up, use a SmartSolar Control display.
