Helloo.. what battery bank woulf be more suitable. I have a 8kw sunsynk inverter. 12x 595w JA panels. What battery should I look at?

Well... it depends on how much power you are using, and especially how much is used at night. Also how much you want to have in reserve any given time? Are you trying to save money? Are you mitigating against outages? And etc.

I have 10kWh, but I have tried to use as much power as possible when the sun is up, and I'm pretty much coasting in the evenings in term of electricity use. Not none, but no big loads (EG no water heating). That will get me through the night, then on an overcast morning with loadshedding early in the day it will get me (maybe not anybody else, but me) through to at least 10:30 before I have to start getting anxious about keeping the lights on.

So get some data, think more about your aims, then the recommendations will get better (or will become apparent to you).

Pretty much what @Bobster. said. I have a 12kwh GEL bank that supplies the whole house excluding the Geyser which is connected to Eskom. It powers everything the whole night and I have never seen it drop below 65% and sits around 75/80% in the morning just before the sun comes up 99% of the time. The inverter has not used Eskom for months. All the big loads are run during the day and I am always fully charged by the time the sun goes down (The perks of generating a bit over 3x from the solar panels than the house kwh usage).

It is all down to usage. I have a pool, outdoor koi fish pond with air and water pumps running, and everything you would expect to find in a 3 bed, 3 garage house. My consumption excluding geyser is less than 220kwh a month with the last 3 months being about 175kwh a month as the pool is only running for an hour for the winter.
