Lithium batteries and new solar charger
I am replacing my 4 6V batteries I think 2 lithium, have never been impressed by the 30A PWM charger for my 600W solar, probably my fault for using 8 avg wire on a 9m run. Thinking if I get a Victron ...

Sorry I missed "maybe adding 2 more panels". That would be what - 1,000W total? When wired for nominal 24V, this would be 37V max, 25A max, post-controller about 73A. Then - yes, you need 75A controller. On the Morningstar website there was a calculator to figure out how many panels and in what configurations you may safely wire with MPPT.
Keep in mind that on sunny day in winter (this would be June-September in Australia) your harvest will be 1.5-1.8 times less than in summer. It might be sunny but the sun is low.
