Except you're just wrong.
By the time you deploy enough solar and wind to charge the batteries *as well as* supply the load while the batteries charge, you're deploying ~6-10x your required load in watts. Add to that the MWh required (remember, power vs capacity), and you'll also need 3-4x the amount of storage as your daily usage - most of the time, that will be idle and unused.
Capacity factor in renewables still isn't anywhere near traditional generation - whatever type you compare it to. Nuclear is normally north of 93%, solar and wind still sits around 25-30% in most deployments.
