What a panel can produce into a loaded circuit aka grid tie or full load
Is one thing
What it can do while charging batteries which are a resistance load is different
I have over 600 watts of solar and 675 amp hour battery bank
I have never gotten 250 amp hrs in One day
Even on a perfect solar day with no generator use and a bank that never got full
I have gotten just over 2kwHrs in One day , 140+ amp hrs
And that was with twice your 300w for 125 amp hrs
That 125 amp hrs statement is very questionable
Granted if you have your 300w tilted into perfect sun on a cool clear day you can come closer than what my flat panels get, but not with a 100 amp hrs battery bank,
Once that battery starts charging the charge rate is going to drop off
