Battery install

Noob question

I have a bank of 48v forklift batteries and I would like to add them to my house. I have 2 solar arrays, one in my shed 5kw inverter and another attached to my house 2kw inverter. I would like to have the batteries in my shed as it gets to minus 7 in winter.
What is the best way to add these into my system utilising both solar systems for charging? what equipment do I need?

Thanks

What battery chemistry? If LIFEPO4, minus 7 in winter is a problem.

Just use the 5kw in the shed, and don't worry about the 2kw in the house.

If you really want to use the 2kw, post: diagram of setup, and detail all the equipment you have.

Sorry, I forgot to mention they are lead acid.
Can anyone advise a cheap setup, i don't want to spend a lot on installing these batteries.

Need more details on these inverters. Are they 48v all in one inverter/charger combo units? What are the existing batteries?
