The problem with air cooling, is it's the air cooling that makes most of the noise. If you get watercooled, then they are far quieter, and you don't actually need that big a water cooling system. Using a big bucket of water is an easy option, but you could create a far more compact system using a small cooler.
Yes I have heard they are quieter. think it will be the water cooled option I might go for. I have seen that some people use a PC cooling system as opposed to long pipe lengths and water butts or buckets.

Are the inverters difficult to wire, i have heard that they come with little or no documentation?
