Excellent news! Thanks again. Now, going back full circle to the solar, I have yet to see my 2 120W panels produce much more than 100W according to the MPPT. Saturday it was full sun and high 30s so pretty much perfect conditions to get some solar. I gained back all 11Ah I consumed during...

Regarding the DC converter, I’m going to adjust it so it’s closer to 14.4v but is it safe to run at that voltage for a longer road trip? I sometimes am on the road for 12 hours with a few stops for food gas and bathroom. This may be right after the trailer has been on shore power so battery...

Got it! I will do the 70% test next time I get out, hopping 2 weeks or so. That is correct the wiring is 18# from the wiring harness near the engine to the DC/DC converter. I’m happy with the results but this solution is a product of all of the help I received here so I can’t take full credit...

So next steps I think are to do a capacity test once this thing sits on the shore charger for about 24hours right? Should I run it down to 10.5 or cut it off at 11v? When normally using, should I avoid using more than a certain amount of the overall capacity before 10.5v? to clarify, you are...

Good tip, did exactly that when I parked and everything including the DC converter were cold to the touch. It looks like I gained 12Ah back into the battery during the drive (plus a bit of sitting at camp testing and helping my buddy pack).

Now were cookin w electric!! Adjusted the little knob till I saw 14.25 on my multimeter in the output of the DC converter and looks like Im generating some power back to the battery! 1 hour drive home should show me any progress.

Havnt tested the Mean Well yet since it actually uses the same wiring to the battery as the mppt for testing. Everything is on Powerpoles. Seems like I have a bunch of testing to do!

14.6 at the MPPT, 14.45 on the BMV and 14.57 at the terminals.

Testing some solar this morning. Winds are crazy so my portable panels are a challenge but they seem to be doing ok on the awning.

When I stopped for firewood I checked the voltage at the plug going into the DC converter (12" from the device, 14' from the 7 pin connector) and it was 14.something with the truck running.

If I'm not mistaken its all 18# for the Aux like the lights.

I dont have trailer brakes on my rig and I am actually using the aux cable not the brake cable of the 7 pin connector so Im not sure I would be affecting it if I had them. Lots to test and tweak tomorrow with this little gizmo, seems the most complicated piece so far haha!

Thats correct dumb charger nothing smart about that one. Im not looking for massive charhing just a bit of help while I drive from the garage to wherever before I can deploy solar or hook up at camp if thats an option.

That reading was off the BMV while I was driving

Sounds like I have a bit of work to do tomorrow! Yes it currently is running straight from DC/DC to the battery through the shunt. Can/should I run it through the MPPT? Not quite sure what you mean I should adjust at the Victron...the BMV? Battery...

Here is the DC/DC converter I am using. I will troubleshoot things tomorrow when I have some time during daylight. Ran out of time today between dropping off the trailer and getting back to camp from work. Stoked to get some things tested out in sub freezing temps! MEAN WELL SD-100A-12...

Well Im on the road and I dont think the DC/DC is putting out any power to the battery.

Cool thanks! What is a good high voltage # to set for an alarm on the BMV?

Ha! Sold on BT BP now!! Less hardware and holes in my precious wood! Those panels took so long to finish to meet my standards so punching holes makes me cringe. History has been reset on the BMV and I added a washer and lock washer under the nut on the terminals. random question but can...

I normally pull the inline fuse between the battery and fuse panel. This doesn’t help with cut off on the shore charger but I’m really crunched for space and trying to keep things too neat. I’m hoping this will be set for a while once I get the DC/DC permanently mounted and the BP installed.
