1.7 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 1.8 for user defined sttings
1.7.1. Bulk
During this stage the controller delivers as much charge current as possible to rapidly
recharge the batteries.
1.7.2. Absorption
When the battery voltage reaches the absorption voltage setting, 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.
1.7.3. 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.
1.7.4. Equalization
See section 3.8
1.8 Configuring and monitoring
- Bluetooth Smart (VE.Direct Bluetooth Smart dongle needed): connect to a smartphone or
tablet running iOS or Android.
- Use the VE.Direct to USB cable (ASS030530000) to connect to a PC, a smartphone with
Android and USB On-The-Go support (requires additional USB OTG cable).
- Use a VE.Direct to VE.Direct cable to connect to a MPPT Control, a Color Control or a
Venus GX.
Several parameters can be customized with the VictronConnect app.
