I have an inverter MPI 12KW WP with 4 CHINS LiFePO4 Battery 12V 300Ah Lithium Battery, 16 550Watt solar panel.
I don't have complains.
One of the concerns I'm having is regarding the batteries. What's the idea cutoff voltage for these batteries, the bulk charging voltage, floating charge voltage?

I have the following numbers, based on probably wrong assumptions

Bulk charging voltage/Battery absorption charge voltage: I have 57.6 Reason behind that number. According to the reference of the battery charge voltage is between 14.2 ~14.4. So 14.4x4= 57.6. Checking data from solar assistant, I have never hit that number only 56.8. (14.2X4=56.8). Should I download this number?

Floating charge value: I have 54.4, reason I found it on this article, but have my doubts, that should be the number https://footprinthero.com/lifepo4-battery-voltage-charts.

Cutoff voltage: I have 49.9 no specific reason why, just place it.

Would like to know your recommendations, as I don't have a clear vision on these part.

Thanks
