Charger & Inverter Settings

General settings that apply to most equipment.  For Victron BlueSmart Chargers, please refer to the BlueSmart product listing page for exact parameters.

Multiply voltages by 2 for 24v systems and by 4 for 48v systems.

Charge Current (Per battery): 40a Preferred (50a Maximum)
Absorption Voltage: 14.6v preferred (14.4 Minimum)
Float Voltage: 13.8v preferred (13.6 Minimum)
Equalization: DISABLED
Low Voltage Disconnect (LVD): 11v

Equalization:
MUST BE DISABLED.  SET DURATION TO 0 MINUTES.
If you can, we recommend setting the equalization voltage to 14.6v.  With this set at 14.6, if an equalization is somehow triggered, you will not damage your battery.

Victron Settings For SmartShunt & BMV-712 / SOK Battery

Battery Capacity: Varies depending on system.
Charged Voltage: 13.8 (*2 for 24v & *4 for 48v Systems)
Discharge Floor: 10%
Tail Current: 2.00%
Charged Detection Time: 3m
Peukert Exponent: 1.05
Charge Efficiency Factor: 98%
Current Threshold: 0.10a
Time-to-go averaging Period: 3m
Battery Starts Synchronized: Disabled (NOTE: you will need to fully charge your battery to sync up SOC%)
State of Charge: 30% (NOTE: Set this to 30% with brand new, untouched batteries.  They ship at 30% SOC%.)

Comment on Discharge floor:
Let’s say you setting this at 10%; when you get to 10%, the Smartshunt will indicate 10% remaining and 0 minutes until empty.  If you choose to fully discharge your battery (not recommended) then set this to 0%.  If you want to be more conservative on your time remaining, then set this to 20%

Settings for Victron MPPT Charge Controllers:

Battery Voltage: Set depending on system, normally 12v.
Max Charge Current: OK to set as high as desired, but no more than 50a per battery
Charger: Enabled
Battery Preset: User Defined
Expert Mode: ON
Absorption Voltage: 14.6v
Float Voltage: 13.8v
Equalization Voltage: 14.6v
Rebulk Voltage Offset: 0.40v
Absorption Duration: Fixed
Absorption Time: 15 Minutes (This allows for proper cell balancing)
Tail Current: Disabled
Equalize Current: 0% (For safety we don’t want equalization at all.)
Automatic Equalization: Disabled
Equalize Stop Mode: Automatic (On voltage)
Maximum Equalize duration: 0 Minutes
Manual equalization: DO NOT CLICK START
Temperature Compensation: Disabled
Low Temperature Cutoff: Disabled (unless you add a temp sensor, the BMS has this protection built in)
