Most any of the 48v solar inverters will have lithium profiles and will charge the battery even if you don't have solar. Growatt is a good choice I have 3 of them, 2 in my house thats been online for almost 3 years and a big split phase unit in the coach. I know everyone loves victron but there is good stuff out there a lot cheaper. If you go with 48v are you going to keep your house batteries? I kept 2 8ds for house and used the remaining 4 8d batteries in series for the 48v inverter. Make sure what ever you do to isolate the 48v from the house side but they can carry a common ground.

Carl which unit and model inverter did you choose?
