1.8 Automatic battery voltage recognition
The controller will automatically adjust itself to a 12V or a 24V system one time only.
If a different system voltage is required at a later stage, it must be changed manually, for
example with the Bluetooth app see section 1.9.
1.9 Adaptive three step charging
The controller is configured for a three step charging process: Bulk – Absorption - Float.
See section 3.8 and section 5 for default settings.
See section 1.9 for user defined stings
1.9.1. Bulk
During this stage the controller delivers as much charge current as possible to rapidly
recharge the batteries.
1.9.2. Absorption
When the battery voltage reaches the absorption voltage, the controller switches to constant
voltage mode.
When only shallow discharges occur, the absorption time is kept short in order to prevent
overcharging of the battery. After a deep discharge the absorption time is automatically
increased to make sure that the battery is completely recharged.
Additionally, the absorption period is also ended when the charge current decreases to less
than 1A.
1.9.3. Float
During this stage, float voltage is applied to the battery to maintain a fully charged state.
When the battery voltage drops below float voltage during at least 1 minute a new charge
cycle will be triggered.
1.9.4. Equalization
See section 3.8.1
1.10 Configuring and monitoring
Configure the solar charge controller with the VictronConnect app. Available for iOS &
Android devices; as well as macOS and Windows computers. An accessory might be
required; enter victronconnect in the search box on our website and see the VictronConnect
download page for details.
For simple monitoring, use the MPPT Control; a panel mounted simple yet effective display
that shows all operational parameters. Full system monitoring including logging to our online
portal, VRM, is done using the GX Product range
