Do not change settings unless you know what they are and what the effect of changing these settings will be.
Incorrect settings may cause system problems including damage to batteries. When in doubt, seek advice
from an experienced Victron Energy installer, dealer or distributor.
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. If the battery voltage is less than 7V during automatic detection, the battery
voltage will be temporally set at 12V and the automatic detection is rescheduled for the next power-up.
The solar charger will not automatically detect a 36V battery. This will need to be set manually.
After automatic detection has taken place, the battery voltage can be changed and set to 12, 24, 36 or 48V, if so required .
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 on VictronConnect.
• 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.
When the unit is powered up the next time it will again perform the initial automatic voltage detection.
Max charge current
This setting sets the maximum battery charge current. It is by default set to the solar charger's maximum 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".
