just reporting what I have seen on the meters. Must be working half way right as I make it thru every night camping off the power grid just fine haha...
Here is where my meters are tapped in the system about five away from the PD9260C.

I'm down to two 85AH battery now after 6 six years of use and trailer is still buttoned up. Planning on setting up again in a couple of weeks here.
My interstates always did recover real quick when re-charging... When I am connected to shore power the PD9260C shows around positive 6 amps all the time on the current meter unless I kick in something that draws alot of current. Then the current meter will show more positive amps being drawn. If it is positive then it is being provided by the PD9260C. If it shows negative then it is drawing from the batteries.
The only time I see negative amps being drawn is when I am running off the batteries with no shore power connected. I have sometimes seen as much as 20 amps being drawn by my 120VAC and 12VDC items in this mode.
I will write a more detailed description for my files when I attack the system again next month.
I will STOP telling my battery story until I do more local tests with my Sears clamp on ampmeter and write it up again. Sure don't want to dispute what the XPORTS have to say about it...
From what I am hearing I must be way out in LEFT FIELD. I know I must put back into the batteries that gets taken out. My only big battery drain is usually from 8PM to around 11PM where I see a good 20AMPS being drawn for the two hours or more. The rest of the time I only see around 1 amp being consumed. Then around 8AM the next morning I see around 12.0VDC reading on my meters... Looks like I am putting back into my batteries around 53AMPS for 10-20 minutes and then 6-8 amp for around almost 5 hours... You are saying this does not offset the 20AMPs drain for 3 hours and the 1AMP drain for 9 hours.... When I start up the generator the second time during the day at 4:30 to 7:30 run time it almost duplicates the above readings starting out at 50AMPS or so and then dropping back to 6-8 amps for the rest of the time. ???
I will monitor it better when I get setup again and can reproduce all of this in my CAMP BACKYARD.
Like I said however I have been following this procedure for a few years now and maybe have camped off the power grid ten weeks or so total over the past couple of years. Made it back home every time by just running my 2KW generator for usually two hours in the morning and then three hours in the afternoon before starting my battery run again for that day/night period...
I must be reporting wrong numbers
Thanks for the reality check...
