Seeking advice on Inverter/charger settings. I use my gen a couple times a day to fill my pressure tank and I’d like to maximize that charging time. The lithium iron phosphate batteries have such a flat voltage curve that even at 70% the charger goes straight to float charge. I have a magnum mm1224. It has a remote so I can manually set absorb and float. My batteries are 280ah configured to 24 volt. What settings do I need to get the charger to kick into bulk charge? Thanks.
