The OP is not out of the woods just yet! :(
What drove me crazy with my first PowerMax, which was a WFCO clone with that 13.2 trigger thing, was you had to get the batts so low to get it to do Boost same as with a WFCO.
I complained to the PM boss, saying, "Whyinheck can't I recharge from 60% SOC in Boost? Why do I have to run the batts down even more to below 50% before I can recharge them back up again in Boost? This is beyond stupid!!!!"
The PowerMax boss paid attention. :) Soon, it was fixed so you could now start off with the batts at 60% or whatever, and the converter would kick off in Boost no matter what. (Same as Iota)
The OP appears to have solved his WFCO issue for when the batts are low enough, but is still stuck with that 13.2 "issue." If you want to recharge with a "Boost" voltage when the batts are not so low as that at first, then you still need a different charger.
