Warning
The LFP (Link Fault Pass Through) function works only when both
two converters own this capability in pairs. Furthermore, both LFP
converters should be supplied only by the same
manufacturer/vender. The connection coming from LFP converters
with odd models or non-LFP converters will cease the LFP function.
