Thank you
Their answer:
"The converter you have is not an actual lithium converter but will charge to approx.. 90%. We do have a direct replacement converter that is lithium Part# WF-8950L2-MBA".

That statement is subject to interpretation. If the LiFePo4 batteries do require 14.6 volts for a full charge and your inverter with a max voltage of 14.2 volts will not charge the lithium batteries to the maximum during bulk and adsorption phases. The corollary is all lithium batteries will reach maximum charge during the float charge. All this is based on the lithium batteries internal battery management computers software. Just like a 12 volt lead acid battery is composed of six 2.13 volt cells; a lithium battery is composed of four 3.2 volt cells. Because the current limitations of a lithium battery, it has an internal battery management computer. This controls the charge and discharge rate and voltages because the lithium batteries have little internal resistance and can easily catch fire if abused. Each lithium battery maker sets the limits for their battery to protect the individual cells, so their recommendations are for their batteries alone.
