Could somebody share there Radian GS8048a battery settings with homemade Lifepo4 batteries?

It doesn't really matter the brand of inverter you're running, I reviewed the manual, and your Outback unit has a pretty standard 3-stage charger in it with user adjustable settings for absorption and float. You mainly need to make sure equalization stage is disabled (either with discrete setting, or by setting equalization voltage to same as absorption voltage to effectively disable it)...

Have a look at these 2 threads for more information about setting a good number for inverter low voltage cutoff, absorption voltage, and float voltage.

On my systems, I just went with the Will Prowse - Recommended Charge Profile for DIY LiFePO4 Batteries *Sticky Post* (first link)... They work just fine for my setups so far.

Thanks Samsonite801
I guess I don't understand the "sell Voltage" under AC input Grid.
What is its function?
My system charges every day for about 6 minutes
Battery voltage is around 53.2 and the sell voltage is set at 53.2
Thanks

See if this article can help clear things up. It appears sell voltage is the sell back to grid voltage (offset) where it can divert back out.
