Been working on improving my house bank setup and realized something that I've been puzzling about all day.
My dedicated 12v house bank batteries are wired to a 12v inverter in parallel, so the inverter has a lot of amp hours available at 12v.
My stbd 32v engine start bank has four 8v batteries wired in series to a 32v inverter and serves as a backup house bank.
An inverter selector switch determines which inverter supplies AC power to the house at any one time. They can't both be on.
But the 12v inverter sucks 12v from 4 12v batteries in parallel, while the 32v inverter sucks 32v from four 8v batteries that only reach 32v bcs they're wired in series.
Which is "better"? Are there pros and cons?
