I have almot the same setup here except I am using the PD9260C Converter/charger and I do not have the TM-2030 Battery monitor. I am using a remote BATTERY MONITOR panel which is reading my 12VDC level from my battery bank and also reading the DC Current being demanded from the 12VDC items being used in the trailer. When I am in charge mode this DC AMPS meter also shows how much current is being demanded by the batteries when being charged... My battery bank is three each of the Interstate 12VDC batteries which are probably the same model you have. The Standard issue Interstate Battery from the Trailer dealers.
When I am first connected to shore power or running my PD9260C from the generator I immediately see the PD9260C go into BOOST charging mode and will read the 14.4VDC on the remote meter panel. If the batteries are fully charged (12.6-7VDC) then this will drop back to the 13.6VDC level in just a few seconds... If there is no activity in the trailer this will eventually dropback to 13.2VDC but as soon as something kicks- in to draw DC current then this will revert back to the 13.6VDC level
Having the remote keypad I can manually force the PD9260C into any of its smart mode charging modes but depending the Battery Bank charge level it will revert back usually to the 13.6VDC level within seconds... In other words I cannot force my PD9260C to stay in the 14.4VDC charge mode if the batteries are already charged up. This depends of the charge status of the battery bank...
I am not familiar with the TM Battery Monitor meter but I know it is one of the favorites panels folks have for monitoring their battery.
In my case I will monitor my battery bank DC VOLTS and when it starts approaching the 12.0VDC level when camping off the power grid this tells me when I am getting close to the 50% charge state of the batteries..
When I get into this 12.0VDC state which is planned to happen around 8AM each morning I fire up my generator and plug the shore power cable of the trailer into the generator. Then my PD9260C jumps to the 14.4VDC Charge state and stays there for around two hours while charging my batteries. My DC AMP meter starts out showing around 53AMPS DC Current at first and this starts dropping back and after two hours the DC Current has tappered back to around 8AMPS DC current. Then I see the PD9260C drop down to 13.6VDC and my DC Amp current drops back to around 6AMPS DC current. It will stay in this mode after that. I then shut down my 2KW Honda generator after doing this mode for another hour. This being our breakfast time when camping we will make up our COFFEE for the day and stored up in a thermos and Momabear may be using the electric skillet etc...
I have duplicated this routine many tmes when camping off the power grid with my setup...
My only wish is I would really like to have the low battery bank ALARM your TM meter will do which is settable as I recall whch of course I would set mine to the 12.0VDC level.
Your setup should duplicate this routine pretty close I would think...
