I know 400 is plenty because I have been doing it with a stand alone fold up ground setup for two years at 200 watts.
We are just the two of us and watch very little TV and use on a few hours computer a day.We have a 2 battery system ( 6 volt each ) as well as a deep cycle 12 volt for the bedroom TV and 12 volt fan only.
The only time we have ever used the gen is for the AC on a few hot days and maybe a few times for recharges and that's it.
I only want the extra 200 watts so we can watch a little more TV if we want to on a rainy night.
We changed our lighting out to LED's several years ago.We just don't use the power some folks use.
A. Be careful of the math, since going from 200 to 400 is not double when you are also going portable aimed to 400 flat. EG 230w is perfect for us with that 230 in a portable on the ground and aimed a few times during the day as the sun moves around. I ran a test where and when we do that and found this was equivalent in daily AH haul to 370w flat. (there and then--yours will be different)
So depending on a bunch of things, you might not be gaining as much extra TV time as you expect.
B. Not clear how you recharge the 12v "TV" battery and the pair of 6s with one solar set up.
Maybe hang on to the portable set after you get the 400w flat on the roof. Could put the portable on the 12 and the roof set on the pair of 6s, or the other way around. You can also put the portable on the same battery bank as the roof set if you like.
Less complicated to have one house bank and an inverter to run whole house. Then you can have a 120v TV and watch it anywhere in the rig for instance. One solar set to do the one house batt bank. (MH engine battery can share with one of those MH arrangements for that, or have its own solar set)
