I don't know much about wind.
A solar controller sized to match peak output is the minimum to harvest all the solar produced at peak output. 400 watt / 12 volts is 33 amps. Add a little for conversion loss. A bigger controller won't provide higher wattage than the panels produce.
The inverter charger sized to match what the battery bank is capable of absorbing when the bank is deeply discharged will be most efficient especially for some brands of AGM's. Check mfg. specs. This is especially important for genrator charging where you want to minimize charging time.
Legacy or Legend brand AGM's (I can't remember), give more life time discharge cycles when charged fast. Check battery mfg. specs. Possibly it was 20 amps per 100 amp hours of batteries. So, 80 amps or so. (This is not the same as the inverter watts. The charging circuits will have their own output rating.)
Generally speaking a small charger will work OK. It may take longer for deeply discharged batteries. A larger charger up to a point will decrease early fast charging time. Batteries have an absorption limit. A charger that is larger than the limit will not charge the bank faster.
I wish you good luck and happy trails ahead!
