New converter PD4655 doesn't go into boost mode Part 2

[RobertL0]

I have copied my initial complaint below regarding my installation. Amended to that, is what I observed 2 days ago when I brought my batteries down to 45% per the TM-2030 battery monitor

""""I replaced the WFCO converter in my 2015 class C with a Progressive Dynamics PD4655, since we boondock and would like to charge my 2 house batteries quicker when using the onboard generator. I also installed a TM-2030 battery monitor. The two house batteries are 24DC-4, which have a reserve capacity of 130 min each Last week, while boondocking, I observed the TM-2030 showing a 55% battery charge remaining and fired up the generator. I saw the green light lit steady on the converter circuit board stating that we were in "boost mode". But according to the TM-2030, the volts going into the battery was showing 13.6, not the 14.4 boost mode should provide. I hit the Charge Wizard button to cycle through the 3 modes, but still it only showed 13.6 volts in "Boost Mode". I have the wiring schematics for the coach and they used 2 gauge cables in all battery connections. I did not run the generator too long that morning so I never timed how long or how many amps was put back into the battery. My question is, why did the converter NOT go into "boost mode" """

AMENDED:

With the batteries drawn down to 45% per the TM-2030 battery monitor, I started the onboard generator and observed the following on the TM-2030:

Minutes- Amps going back to batteries
1........... 26.2
2........... 19.8
3........... 19.4
4............ 18.9
5............ 18.7
6............ 18.1
7............ 17.6
8............. 16.9
9............. 16.4
10............ 16.2
11............ 15.8
12............ 15.5
13............ 15.3
……
20............ 12.8 Battery 48% recharged per TM-2030
….
29............ 11.3
….
37............. 10.0 Battery 52% recharged per TM-2030


What happened to the boost mode?

call them they,ll help you out, I have the same unit,and not a problem.

The trimetric is either not zeroed properly and your actual state of charge is higher, and/or the PD is faulty as it should seek and hold 14.4v when asked for 'boost' via pendant/wizard.

I'd expect 2 50% depleted group 24's at ~8-AH capacity to be able to suck 25+ amps each initially for at least 20 minutes before battery voltage approached 14.4v and amps begin to taper.

Perhaps PD getting confused by solar voltages above 12.8v, but boost button should seek 14.4v for 4 hours, and if it is not, then It no workkeee as designee
