5.2.1. Battery settings

Battery voltage
The battery voltage is automatically detected at the very first power-up of the solar charger and the battery voltage is set
accordingly. Further automatic detection is disabled. To make sure that a stable measurement is used, the charger first waits 10
seconds, and thereafter takes an averaged measurement. Note that the solar charger will remain off during this time.
In case the solar charger does not measure a battery voltage, it will default to 12V and store that. This will happen if the solar
charger is powered via its PV terminals, while not connected to a battery.
After automatic detection has taken place, the battery voltage can be changed and set to 12 or 24V , if so required .
Tip:
If the firmware of the solar charger needs to be updated, while keeping the automatic voltage detection active,
for example before shipping the unit to an end-user, do the following:
• Update the firmware.
• Once the firmware update is complete, go to the settings page in the VictronConnect app.
• On the settings page, click on the three vertical dots in the upper right corner and select "Reset to defaults"
from the drop-down menu.
• Un-power the solar charger within 10 seconds.
The next time that the unit is powered up, it will perform the initial automatic voltage detection.
Max charge current
This setting sets the maximum battery charge current. It is by default set to the maximum solar charge current.
Use this setting to reduce the charge current, for example, when a smaller battery bank is used that requires a lower charge
current.
Charger enabled
This setting enables or disables the battery charger. It is by default set to "enabled".
This setting can be used when work needs to be carried out on the installation. When this setting is disabled, the batteries will not
be charged.
Battery preset
This setting sets the battery charge algorithm. It is by default set to "rotary switch".
A selection can be made between:
• The rotary switch position.
