Greetings Raz...that sounds like a fun little test. Might do that on my next day off. thx : )

PS note...just for giggles i went out and turned on 4 of the LED light fixtures (i removed all covers in case there was any heat build up overnight) and will run them for 12 hours (i will check before heading to the office tomorrow at ~0530)...that is another ~13 amps being drawn out of bank during that time... At that point i will check the voltage. If it has hit ~12.5 or less i will plug in the PD4045 and monitor. Who knows??

Mine neither, and the two PD techs made no mention of this as an option to check.

(This was also posted over at my Parkliner #35 build thread for documentation/archive use.)

I have just completed a two hour test of the PD4045 in my Parkliner #35 as suggested by Raz (thx again!). It was a fun quiet time with my kindle paperwhite and a good read out in the PL on an overcast mid-60's Oregon coast day : )

I took notes each 15 minutes on what the readout on the Xantrex LinkLite, Bus-Bar-Meter (the PD4045 is connected directly to the Bus-Bar also), and handheld VOM off each battery. My findings in summary were the PD4045 sent out ~13.5volts at an average of ~6amp over the two hours with a beginning battery voltage of 12.45 volts before hooking up the PD4045 to our 30amp service. The max voltage was 13.52 volts and max amperage for first 15 minutes was 8.2 amps. Here is a listing of each 15 minute reading:

Time..........Bus-Bar..........Xantrex..........VOM..........AMPS
0000..........13.4................13.5............ .13.45..........8.2
0015..........13.4................13.5............ .13.46..........7.6
0030..........13.4................13.5............ .13.46..........6.9
0045..........13.4................13.5............ .13.47..........6.3
0060..........13.5................13.5............ .13.48..........5.9
0075..........13.5................13.5............ .13.49..........5.2
0090..........13.5................13.5............ .13.50..........4.6
0105..........13.5................13.5............ .13.51..........4.1
0120..........13.5................13.5............ .13.52..........3.7

I ended the test at this point as it was twice the allotted time that Raz suggested that the PD4045 should go into "Boost Mode" and show 14.4 volts. Obviously this never occurred. Though, in discussing the unit with PD techs over the phone last week and running some suggested tests with them in the loop the unit was said to be working according to specs. So as i've stated, i really don't know what is up at this point, nor actually do i care since as stated i will be using the 12volt DC side of the system and not the 120vAC side so having the PD converter hooked up is a non issue since we use the rig off grid and what i'm after (and always have been) is simply to keep the battery bank healthy. If that means a high quality stand alone charger (such as the Optima arriving next week) so be it. Nothing lost, yet good knowledge gained in the experiment.

I will post the results of the test with the Optima charger once installed. I will draw the bank down to the same starting level and take readings at 15 minute intervals for two hours to compare and then also post as to when bank is (i hope!) topped off which has not happened yet with the PD4045.

Happy Trails! Our next adventure is in another three weeks so this is all good timing and rig will be ready to go with a full battery bank! Yippie.

(a PS note in this post only...in context of this thread...Many thanks to all who sent ideas and suggestions. MUCH appreciated!..this is still a work in progress...as am i : )

Your chart is about what I would expect. The closer to full charge the battery gets the lower the current the battery will take. Depending on how the charger/converter is designed it might take a very long time to get a much higher charge. It appears to me everything is working as designed.

Obviously no boost there. I wonder if your ammeter shunt is interfering? I guess I'd contact PD at this point and see what they say about your test results. Raz

For any traveling through and wish to see my solution for my PD4045 issue i have a short write up on the install i did of an Optima 1200 digital charger in Parkliner #35 at this post_LINK.



Summary...the Optima charger delivered as pointed out in user manual for a ~1/2 depleted battery bank... started out at the voltage of bank (12.5v) and over the next 5 minutes was sending out 13.8 volts. By the third hour it was at 14.4 volts and 4 amps (having a max amp reading of 11.2 amps early in the test).

Overall i'm pleased with how the unit installed in our rig and will of course update as time goes on.

Happy Trails!
Thom
