I am getting ready to start entering all my parameters into my newly installed solar setup and have a question . The controller is a victron mppt100/50 and I have a bmv712 . The bmv 712 asks for total capacity in AH . the mppt asks for several different voltage values . The battery specs (renogy 12v 100A lifepo4 ) say max charge current of 50 A but I am seeing no place to enter that value on any of the equipment . Do the different pieces talk to each other and with info shared between them compute the 50 A figure or am I missing a spot to enter that number specifically ? Thanks for any help . It looked way easier on you tube

As to your other question, The MPPT 100/50 will only charge up to 50 Ah. That is what the second number is on the 100/50. 100 volts maximum in and 50 Ah maximum out.
Renogy should have the settings on their web site to program controller specifics.

Thanks guys for all the input . I believe I have finally got it with the help from you guys and Northern Arizona wind where I purchased most of my components. The biggest problem I had , which I will admit may be due to my own lack of knowledge , was trying to get specs for the Renogy 12V 100 AH lithium batteries. This is what I got from Renogy so maybe it will help someone else down the road.
Absorption voltage 14.4 V
Absorption duration 30 minutes
Bulk voltage 14.0 V
Float voltage 14.0 V
Puekert exponent 1.00
Discharge floor 20% but techs advise to set to 25% for better life
DC input low shutdown 11 V
DC input low restart 12.6 V
DC input low pre-alarm 12.0 V
If any of these values look totally ridiculous let me know and I will re-research them . For the most part they look comparable to other Li battery parameters I have found.Jim , Dianna , Katie , Molly and Sophie
