Samlex Inverter Power Draw Question
I just finished a Samlex pure sine wave PST 3000-12 inverter install. I ran 00/2 cables because that was recommended in the user manual. I added a Renogy 30 amp transfer switch with the charger wired ...

Your 9160L converter will keep the whole Rv at 14.6 when on shore power. the battery voltage will drop to its voltage that goes with being full once the converter is disconnected That is 13.6ish for an LFP.
The monitor does not know how long you plan to run the MW so it is playing catch-up the whole time for time remaining, so you see that fast drop in time remaining the longer you run the MW.
Seems like it is all behaving as it should. If you intend to be on shore power very long, you might consider shutting off the converter and only use it to recharge the battery as required. LFPs don't like to be on that 14.6 float for long periods. You still want 12v in the rig. You can use the battery for that or else get a second converter that floats at 13.6 and just use the 9160L when you need to bring the LFP to full.
PD has a newer version of that converter that has a 13.6v float stage for LFPs.
You can run the MW in bursts so your battery does not hit bottom all in one go. Some recovery between bursts is good.
