hello folks,
I have setup a fairly new, small system:
a 300A CHINS 12.8V 300AH battery LiFePO4
a Victron SmartSolar CC MPPT 100/30
a Renogy 500A Battery Monitor,
a Renogy 200 Watt 12 Volt Monocrystalline Foldable Solar Suitcase (with the PWM CC that I am not using, using the Victron one)
a Novopal 2000 Watt Pure Sine Wave Power Inverter 12V DC to 110V/120 AC Converter
On the Victron CC, I have set up the battery type to LiFePO4 (setting 7)
I have a small load, a freezer, using some 75W, on and off, for testing.
The system works beautifully, charging and discharging, but I have noticed that the Victron CC has a hard time changing STATE, from Float to Bulk, or Float to Absorbtion (as consumption increases and the battery percentage is 80-85%, during cloudy periods), UNLESS I disconnect the Solar suitcase from the Charge controller and manually reconnect the MC4 connectors)-- this does not seem normal, to me. I have the Victron firmware(s) updated to latest.
So, when it's saying it is in Float mode (even though battery capacity is 80-85% and very sunny) -- then I disconnect the Solar Panel from Victron CC, then reconnect, and then the STATE goes back to BULK -- this is a pain, to do manually though.
Am I doing anything wrong? Do I need to manually set parameters for this LiFEPO4 battery type, in the Victron CC? (I've left them to automatic, whatever the specs are)
The battery owner's manual states the following, as MPPT settings:
Charge:
Charging limit voltage: 14.6V
Overvoltage disconnect voltage: 15V
Overvoltage reconnection voltage: 14.2V
Discharge:
Low Voltage disconnection Voltage: 10.8V
Low Voltage reconnection voltage: 11.6V
Undervoltage warning voltage: 12.4V
Not sure how this matches the Float, Absorption and Bulk STATES/settings.
Do I need to make any changes to the default LiFePO4 Victron settings?
many thanks, helping out a newbie
