It seems these 48v battery chargers are still expensive and low amperage, there are forklift chargers and I have some old Telecom battery chargers 50A don't see them for sale much anymore.
However there is plenty of "48V Solar Hybrid Inverter Charger Off Grid" most of them are 80A charging or more and also a solar charger built in, those that don't feed to grid might be a cheap option if they cater for charging at user defined SOC, perhaps in a program or they might have a phone APP don't know, if you use your own inverter and one of these as a charger from grid there would be no interruption to your main inverter when charging switches on and off.
I have an old PIP4048HS and it gas a grid or gen input for pass through or battery charging but have never used that for charging, but I think these new types would work almost the same way.
See what you find anyway.
