It is true, that Li batteries have much greater cycle life.
But for home use, it makes absolutely no sense.
Home systems - either isolated or grid-connected - needs only a few cycles per year from the battery.
Grid-connected systems are only for safety purposes, so they barely work at all.
Isolated systems must have large (like 50-200kWh) capacity to ensure continuous supply. Hence, they have very few charge/discharge cycles per year.
For such systems, lead-acid is much cheaper, than Li batteries.
That's the reason, why home battery systems are usually buit from lead-acid batteries.
