Assistance on new house battery
First off I know very little about this subject but want to learn, so please bear with me.... I have a Harris 27D170 battery as a house battery in my MH that is connected to a 30amp Sunforce solar ...

the battery you mention is not a true deep cyle battery...its a multi purpose battery... it isnt the best for either starting or deep cycle use, but it works well for someone who needs a light, battery with a reasonable charge life when used in moderation... perfect for use in a small system that has very little draw before it gets recharged, like a boat battery.
how many batts do you have room for in the space? as this will determine if you need to stick with 12v or if you can go with 6v batts in series..
the size of the solar charge controller has nothing to do with the size or number of batteries, providing the bank its connected to is 12volt..... to solar charger is sized for how many amps it can safely receive thru it from the panels.
and depending on how much you want to spend, and how many amps you want, will also determine which batteries to buy....
6v batts in series are the most economical in every respect, but there is such a thing as true 12v deep cycle batteries, which I use 2 in my RV (US185HC xc2), which can get you more amps in a limited space....
personally, I would stick with a flooded cell battery, and I would recommend that someone who is just learning how to maintain batteries properly do the same... they have always worked well and will continue to do so for many years to come.
the initial cost of them is cheaper, they will take more abuse, and you dont need to have a charger with special charge profiles... and if you have to replace one because you didnt take care of it right, its cheaper to replace. which with a minimum of maintenance, is rare for a few years.
with all respect to you and others who are learning about their systems, there are just too many "new technology" batteries that are ruined by newbies who dont understand the basics of battery care and maintenance, and that is an avoidable and very expensive learning curve...
