An 4P8S 25.6v battery bank is a good power reserve.
A Victron 100/50 is a nice meaty SCC (i have an 100/30 and its great).
How much will it handle? Lets do some math.
You seem to be undecided for panels so lets find some big cheap ones on craigslist (phoenix?):

330w for $165 - looks great!
Lets arrange an array to stay below 100v for your SCC.
Solar panel Voc: 40.49 (shown in 4th pic)
We can put 2 of these in series for 81v. This is very good, gives us a little leeway for cold weather which can increase the voltage. 2 in series is 660w.
660w / 25.6v (battery voltage) = 25 amps
2 panels in series connected to 2 panels in parallel would give 1320w and would use your SCC nicely near its charging limits. To be honest, 2x of the 330w panels would make a nice backup system in itself. If you want the max, 4 panels in a 2S2P config is the max usable.
So, locate some panels and see how the Voc works out for building an array to work within 100v SCC and maximize the 50amp (if you want to maximize that is).
Come back when you locate some panels, check back in with a few if you want opinions or want to check the math or array config options.
