Pulling that much out of any type of lead acid battery will significantly reduce it's life.
By lithium next time.

It really depends on how often he needs to deep cycle. Even at 80% DoD, he can get hundreds of cycles out of AGM's, so if he only deep discharges a few time a year, he may never see a payback on lithiums.

4-5 times the nominal panel rating in watts is what is normally assumed...so 1600w-h per day out of 400w of panels makes sense.
Overcast, small shadows, shorter winter days, etc...can really kill output.
