FYI- all the Victron stuff works just fine even out of internet range - the only thing you lose is access to looking at it from the internet?.
800w / 24v= 33amps of possible charge from an array.
Your batteries are Lithium? Right?
33 amps / 200 amps = .165C that is just about what Ampertime recommends - a .2C charge rate. So adding a second array could be problematic. Now when the sun isn’t shining strongly- then no problem. A lot depends on how many watts your panels deliver (latitude, angle, season, etc.).
I don’t know if your SCC (solar charge controllers) have this setting or not. My Victron mppt’s you can set a total charge rate and the mppt will communicate and not exceed that rate.
One other possible option would be to add another 24v battery (if there is room and budget) - look for a 24v battery instead of two 12v.
(I would probably add the second array even though it might go over - but my panels are flat - so I never see max power).
Good Luck
