I have since upside the wiring to 8 mm2 all around for battery wiring, but still not fixed. I have since added an acessible switch so that I can isolate the charger when plugged in and the battery is full. If yours is the same as mine with large luna fridge, the cable to the fridge is undersized. The voltage drop in the cable will cause your fridge to trip off at 60% battery and all because the high current in the small cable causes the voltage at the fridge to get below the fridges high trip set point. The can be temporarily fixed by just seeing your fridge trip to low. However, you should try to get conqueror to fix this for you as the wiring is not sized as per fridge manual. Also, the interior light on mine was spliced into fridge cable and not properly fused for the tiny wire. I highly recommend you get a Vitron battery monitor, $200 on Internet, to monitor your battery. The inboard one is a waste of space. All in all, I love my UEV, but the wiring as delivered was not great. If your not confident in doing it yourself, I would recommend a professional wiring upgrade when the funds allow.


HI Guys,

Camped at Newnes for the long weekend. Had a great time. Had a mix of all different weather from warm to cold to wet. Overall the camper performed well. I was extremely surprised how well the fridge ran and how little power we consumed. After 4 nights and very little solar input due to lack of sun we were still at 12.35v when leaving. I checked for voltage drop at the fridge didn't notice any real drop and wiring appeared adequate. Maybe they have heard the complaints and are using better wiring?

The most interesting and annoying thing for me was the level of condensation in the camper, especially on the roof. It was quite mild weather in the evenings yet there was so much condensation on the roof, I would hate to imagine what will happen in colder high country camping. I wonder if it has something to do with the vinyl/rubber roof? We even had the upper windows open. The same was experienced with the awning, the vinyl/rubber L-shaped awning would have condensation on the underside some mornings and the water would start dripping from the lowest point in the awning, very annoying. Is this to be expected with this setup, have others experienced the same?

Cheers,
Oliver

Hi Oliver,
Yes, we have had the condensation issue too, but not enough to be a real bother that prevented us from packing up.
We have the 90l dual compartment fridge, and also reckon it is very efficient compared to our previous Waeco and Engel.

Just looking at your photo, is your awning a single piece L shape, or is it two pieces with a zip/Velcro join?

HI Ben,

The awning is 2 piece that is zipped together with a flap over the top. Do they make a single piece?

Cheers,
Oliver

Not that I know of Oliver - ours is the same as yours - two pieces, except it is over the front of the trailer rather than over the fridge.
I prefer yours!

Hi Ben, That's interesting. My mate bought a UEV345 at the same time as me and it appears to be the same as yours. I wonder why would be different, seems Conqueror throw in whatever is available at the time.

Yes it is good having the piece over the fridge but it leaves a splayed section up front and not great cover over kitchen area as a result.

Cheers,
Oliver

Did you check the voltage with the fridge running at maximum cooling?  Voltage drop is only measurable when current is flowing.  The voltage drop of a resistor (a cable is a low impedance resistor) is zero when no current is flowing.  In then increases in a hyperbolic relationship to amps.  A cable is like a pipe, the more water you want to send through it, the harder and harder you have to push.  

12.35V is probably high enough that your fridge would not trip even with the high voltage dropout setting.  However, my fridge was tripping when the battery voltage was at 12.1V and the fridge was running at near maximum on a warm day pre trip in the drive way.  After finding it tripped, it wanted to run full boar to re cool the fridge and freezer section.  12.1V with a slow discharge rate is still a relatively full battery.  I believe my Victron BMV600 battery monitor was still calculating 62% battery capacity remaining.

I am just throwing this out there, because I almost lost a whole trips worth of food before I even left the drive way.  All because the factory wiring is 2.5mm squared and according to page 6 of the National Luna refigerator manual the minimum wire size is 4mm squared for 4m of cable, 6mm squard for 6m of cable.  I am not sure on the total meters of cable, but I would guess that I would have 6 or 7 meters by the time it gets from the switchboard under the trailer, to the back and up into the compartment, loops around and into the refrigerator.

I love my conqueror and am fussing with it or taking it out any chance I get, but really the electrics should be given good looking over by all of us to ensure that a good trip isn't spoiled by a tripping fridge or other electrical issue.
