group 31's in parallel?
Group "31" is a size , not a definition of what the battery is usefull for.
I am sure deep cycle G31 are made , but most I have seen are simple truck starting batts .
If you have the room I would consider 4 - 6v or more deep cycle batts* for* the house bank.
Compare the "20 hour rate" if its for the house , and remember its the lead that does the work , and heavier is more work .
If you return to 8D , be sure to get DEEP CYCLE , not starts or the BS "everything for everyone " in between version.
Before purchasing any batts , I would suggect you install a SOC meter, to learn to live with the new set.
Best under $200 you will ever spend ,
Second choice 6v Gollf Cart Batts from Sams Club , no testing , they will swop them for new quite often.
