Hi folks, id be interested in opinions on connecting the output from a vehicle alternator to the genset/utility input terminals on a 'All-in-one' charge controller. (240v UK shore power settings when connected to grid)
Looking for the safest way to protect the alternator charging system, but allow the charger to control the charging profile into a 48v lifepo4 battery.
Would i need a voltage sensing relay connected to a 12vdc to 240vac inverter, hooked up to the 'all-in-one' as an ac input? I assume the relay would only send the(excess) power through the inverter once the vehicle battery was in full state of charge?

Thanks for any thoughts offered.
