So I have 400A/h of lithium batteries being charged by 4 x Victron SmartSolar MPPT's and monitored by a Smartshunt. The MPPT's get the battery voltage via bluetooth from the SmartShunt, and they all have the following settings:
Absorption voltage 14.2V
Float Voltage 13.5V
Re-bulk voltage offset 0.1V
Absorptionduration Adaptive
Maximum Absorption time 0m
Tail Current Disabled
Temperature Compensation Disabled
Low temperature cut-off 5degreesC
My MPPT's happily all go to float the instant the battery voltage hits 14.2V. Good stuff.
The SmartShunt however doesn't recognise that the battery bank has hit 100%. My SmartShunt settings are:
Battery capacity 400Ah
Charged voltage 14.1V
Discharge floor 10%
Tail Current 4%
Charged Detection Time 1m
What do I need to do to make the SmartShuntconsider the batteries full?
