deb - without knowing your power needs first, it sounds like you've just been sold a bill of good to toss into a $hopping cart. Find this out first before buying ANY battery, or being tempted by commercial vendors to throw more items into it.
Until you find this out, stay on the grid. Currently the project is a waste of money and time. The lead crystal ball won't save it.
try looking at Lead Crystal Batteries. These are not flooded cells so they are safer, have high cyclic life, don't gas like traditional batteries (all of these types of battery gas but the levels are negliable),
look at harlandsimonups.com to find out more.

None of the above. Gel is out of the question for RE applications. AGM is OK but too expensive and does no tlast near as long as Flooded Lead Acid.
Next is a huge mistake of using 12-12 volt batteries. I do not know what battery voltage you intend on running but 12 volts is plain crazy talk. So I assume you are looking at 48 volt battery. The capacity you talking about if configured for 48 volts is 600 Amp Hour. That being the case you would not use 12 volt 200 AH batteries as that would require 3 parallel strings. Regardless of what voltage you run you only want 1 single battery string. With 48 volt @ 600 AH you would use either 8-6 volt 600 AH batteries, or 12-4 volt 600 AH batteries. Forget 12 volt anything.

We have a 3kw wind turbine
A 3 kw solar panel array
Inverters etc
We need to order the batteries to complete the set up
I am so confused about the best btteries to use
We think we nee 12v x 200 AMP hr x 20 batteries
We run 240 volts in the house
PLEASE what are the best batteries for us to purchase
Price is not the issue
The best cycles, best long term life the best
