Need help with settings for MPP Solar LV2424

[Jameswy]

I am almost done building a solar generator using a MPP SOLAR HVLV2424. It is tied to (x8) 3.2V 280Ah LifePO4 cells (24V 280Ah battery). I am using an Overkill Solar 100A 8s 24V BMS.

I am not sure what settings I should use for the following:

Program 14. Battery Type
Program 17. Bulk Charging Voltage
Program 18. Floating Charging Voltage
program 19. Low DC cut off Voltage
Program 20. Battery stop discharging voltage when grid is available
Program 21. Battery stop charge voltage when grid is available

Thank for any help. This is my first build and I am a little nervous about messing something up.

That's almost exactly my setup, though mine is basically x2.

Battery type is custom or user.

Voltages, I went with the recommended charge profile in the battery sticky for Victron long cycle life. Going from memory, 28.2 bulk, 27.2 float, and 24v low voltage cutoff. Don't take my word for it, double check.

Grid stuff I have no clue, I only charge from solar. Even when I add charging from a generator, it'll use an external charger.

I printed that page out, and keep it in a binder, along with other important info, in my solar trailer.
