Hello again!
If I want to charge LFP from a lead-acid bank, or vice versa, it seems the two options are a) DC-DC charging; b) an inverter and AC charger.
As far as I can tell, all of these pieces or kit are about 85% efficient, so going via an inverter works out at 72%.
But the huge advantage of going through the inverter is that I would be reusing existing equipment.
Other than efficiency and perhaps a degree of automation, is there anything else to consider? I might only need to set this up as a contingency anyway, although I'm still very early in the research and design phase.
