new power max converter, problems
Replaced wfco 8955 converter with power max pm4b-55-mba converter. I put the new PM in today and followed the testing directions. Step 1. With only shore power hooked up and all DC fuses pulled ...

with the batteries at 12.1 at start, the converter should have gone back to 14.6 after the 15 minute thing, and stayed at 14.6 for some time before dropping to 13.6. As it is, you might as well have kept the WFCO! :(
To prove the PowerMax is working right, if it were me, I would haul it out, use shorter cables close to the batteries (probably with a set of ordinary jumper cables, and on low batteries, make sure it does some time at 14.6 past the 15 minute point. Right now the numbers are confusing, but could be due to voltage drop, don't know.
For generator charging, you need to stay at 14.x once the batts get that high. I like the adjustable voltage PowerMax for that to the highest amps you can run with the generator. Note that the 75 is PF corrected so it draws the same as the non-PF 60. Might be ok with the 1600 if that is VA not watts (A Honda 2000 is 1600 VA).
For generator charging on the 1600, you should set the converter up near the batts same as above, and get some time at the 14.6 volts till it drops to 13.6. If that is close to 80% SOC (hard to tell without a Trimetric)then IMO adopt 50-80s as your off-grid procedure till you can get shore power and "recover" the batteries.
If you don't mind using the 3500, then you could get a 100 amper and use both for a 155 amp fast recharge in Bulk
