Having trouble selecting MPPT Controller

Have 4-200W panel on RV roof, wired series/ parallel, will add 2-200 more in future when more money avaible
1 230 Ah li time battery, will add second in future
1000 inverter, not used, but will upgrade someday

These upgrades have gotten a little pricey

Victron the most recommended, one choice

Victron Energy SmartSolar MPPT Tr VE. Can 150V 100 amp 12/24/36/48-Volt Solar Charge Controller (Bluetooth)@ $519.00

Other recommdations?

What is the Voc of your panels and how do you expect to wire them? (3S2P or 2S3P?)

I have 195w and 200w panels - roughly 24v VOC
I live where it is much colder and ran 3s strings on a 100/50 SmartSolar
That will knock down the price to under $200

Having 800w of panels charging 12v you have the potential for about 65A. You can use a victron 150/70. Roughly $385

Perhaps an Outback Flexmax 80 would be a good choice as well, they can be bought fairly reasonably right now.

2 -200 panels 23.0 VOC and 2-200 Go PRO? VOC? Will add 2 more Renogy panels sooner than later
So would like controller to be good for expansion. Thanks
