If you will also be installing an Inverter, make sure it is an Inverter/Charger and then totally disconnect your existing built in converter, and I mean TOTALLY at the converter supply side so it does not waste power, turning off it's breaker does not do that. I have no idea how many LiFePO4s you plan to get, but if it's 4 or 6 then the new Victron Multiplus II is the best solution. Obviously you will also want the Battery Monitor and the CERBO + Display option
Here is the Inverter/Charger link, the other parts can be found close by.
