Hi,
MPPT:
You can use MPPT only in the morning, when the expected charging power is higher than the solar power.
Usually the solar cell power rating is higher than V_Battery_max * I_charge_max / charger_efficiency
Then MPPT is a benefit in the morning, but you waste (not use) energy at the rest of the day. Mind: You only have limited capacity to store energy....something more than 480Wh.
This is different when you push energy into the grid. You don´t need to waste solar power when the battery is full because you can use all the solar energy to gain money.
I recommend to do some Excel simulations with different P_max of solar cell, different solar cell angles, different seasons.. to find out how much you gain from the MPPT.
The less overhead you have in the solar cell power the more benefit you gain from MPPT, but you risk to go into battery power down.

Also, I found LT8490, which is rated for 10A, did not get 12A rated parts in Liner Technology site.
When I use the selection guide, then there are a lot of
LiIon charger IC with
>12A charging current.
(underlined are my search parameters)
--> What are your search parameters?
