@seanobrien698 i disconnected the small fan 2 years ago and its makes no noise at all. Not sure why they put such a small and very noisy fan on it at all.

@jeffheath2801 they are fairly readily available from ebay or Jaycar

Whats that old saying - you get what you pay for! But that's not even true these days as so much product is generic and simply re-badged resulting in paying more for the name (often a lot more). The Renogy is a good product and well designed and built. I have Renogy in my van and many of my friends have also - they are good value for money.

Not that I know of

Thanks Matt. Its quite the norm here to run 10mm sq cable to the caravan battery and it works fine as long as the DCDC Charger has the ability to compensate for the cable loss as most good quality chargers do - which is the point of this video. Good luck trying to find somewhere to mount an inverter in a modern 4WD tow vehicle these days in close proximity to the battery. There is little space for anything to be installed much less a bulky inverter.

​@@timterry8714 The amperages you were throwing do not represent very much power, less than 500W. How quickly do you want the trailer to be able to charge ? From the diagrams it looked like 250W was fine for your purposes. That's like 1A @ 240VAC or 2A @ 120VAC. 1mm^2 (17 AWG) cable to the trailer and a tiny little inline glass fuse. Judging from a quick amazon search, we're talking quite small... about the size of a small paperback book it looks like, for something in the 250W range. Perhaps not entirely suitable buta commercial version wouldn't be much different. Also, don't a lot of these vehicles already come with inverters as stock these days? Well, think about it. It seems silly to run such a low voltage 10+ meters. -Matt

Yes you could do it that way. Then run a standard mains power charger in the caravan. However virtually every caravan and camper here have dcdc chargers installed and that's the point of this video.

Moving the DCDC Charger closer to the start battery in the vehicle moves the problem from the input to the output and will result in slower charging of the caravan battery and not fully charging in a reasonable time if at all due to cable voltage drop - also what about if its a combined DCDC and Solar charger - the panels are on the caravan not the vehicle. The DCDC Chargers are (or should be ) designed to overcome the input cable loss not the output. This is the whole point of this Video.

@@timterry8714 The point of the DC-DC charger is to limit current draw on the input while, as you state, boost the voltage to properly charge the AUX battery. This does not eliminate the need to properly engineer the system with adequate cable size, which is arguably easier to do on the caravan chassis. When I said "near the tongue of the trailer", I meant ON the trailer chassis, just toward the front. Thanks for the video

I personally would cable each independently directly to the start battery

@@timterry8714 I was thinking that. as I run a 90 ltr fridge in the tray of dmax

It was just a quick list of a bunch of random chargers. I just a look and the minimum input is 10.5v for the Enerdrive.

@@grahambanks7926 hi Graham, they need to be installed by me as there are different power boards on the various models - the fridge looks the same but isn't necessarily electronically.

Where are you located Graham?

Not that I have seen of late. It seems all the manufacturers have downsized to the minimum they can get away with where as in the past there was limited choice and they had to fit what was available from Danfoss/Secop which was the BD35 and BD50 and the Chinese copies initially simply followed suit. The Chinese now build any size the manufacturer specifies. As I say the I think places like Australia, Africa and other very hot climate countries only represent maybe 5% of the global market so they dont care if its "not fit for purpose" for our country.

Hi Paul, yes recently had one in to look at. I guess they are a bit of a beast but not sure of the relevance in today's world as the cost of solar and batteries has dropped so much that the principal of the Autofridge is a bit of a moot point I think.

@@timterry8714 good points Mr Freeze 🥶

Hi Dave, sorry for the delay in replying I only look at comments every now and again. Thanks for the comments. Good Luck.

The link works in Australia so not sure where you are which may cause an issue if your overseas. Just Google the "Breville Bambino" coffee machine. Its still available here.

@@timterry8714 thanks, in Montana, I did just that

I work for myself and from home so my overheads are low and I'm prepared to do this but I suspect it may be difficult to get a "shop front" business to undertake it at a reasonable cost or at all.

@@timterry8714 Oh darn it. Where abouts are you located?

@@RustyTruckAdventures Brisbane Australia

@@timterry8714 Amazing, I am just about to head back to Brisbane. What would be the best way to get in contact with you?

@@RustyTruckAdventures have a look at my FB page and get contact number from there. Cheers Tim facebook.com/12voltfridge/

You dont know what the temperature actually is without a digital temperature gauge. This was one of the issues with the older model. My upgrade fixes that issue.

Amazon I think - it was a long time ago now.

yes

Yes they have a very chequered history in customer service!

what ?

I have no idea.

Exactly!

Glad it helped. Cheers Tim

Yes they will get down to the correct temp for a fridge and even at !00F or 43C if the insulation is good the fridge will operate as a freezer also. The problem with most modern fridges is that the manufacturers have reduced the size of the compressor significantly, use "expander foam" rather than proper cool room type insulation in the walls of the case (no thermal insulation properties) and on some of the larger capacity fridges (a good example is the one in the background of this video!) the cooling fan and condenser have been reduced significantly. No cost saving to the customer I might add! The result is that many of the large 75 and 95ltr dual zone fridges run almost continuously above about 95F or 36C. No good for the hotter countries like Australia.

@timterry8714 we just got one. Plugged it in and no cooling at all after a few hours

Thanks. Glad it helped.

I do but it depends on the model variant you have some are quite straightforward others require rewiring.

Hi Grant, well I guess I was focused on the ability to charge the batteries so the primary interest in my mind was the current these put out after the solar controller (i.e.the battery charging amps available). These panels never put out the wattage specified as its a really not a "real world" measurement in my mind. The rated wattage of a solar panel indicates its electricity output when tested under ideal laboratory conditions (STC). In real-life installations, actual solar panel wattage depends on external factors such as sunshine and ambient temperature. www.researchgate.net/figure/Standard-test-condition-STC_tbl1_326014498

It probably is

Exactlly

No, I removed the fan altogether as its noisy and not required. I did speak to Bushman about this. The Danfoss compressor will run hot in hot weather but they are designed to do this. The conditions they operate in boats and vehicle mounted 12V car fridges with little or no ventilation at high ambient temperatures would surprise you. But they not only work for years in these conditions but manage to maintain the internal temperature correctly. Mine has worked seamlessly for the past couple of years and I have no doubt it will continue to do so.

Well looks like you have a dodgy Bluetti as the reviews I've seen indicate they can accept a peak load up to 2500 watts and continuous loads up to 2200 watts. So I think you should return it under warranty.

@@timterry8714 Is that the AC180 you're talking about?

@@aldavidson1044 yes it is

Best move I ever made! No the Bushman is taller and also a bit wider and only just fitted in the space I had between a wall and the back of the dining seat. I had to modify the overhead cupboard to make it shorter and enlarge the opening width. The fridge works brilliantly and hasn't missed a bit. With minimum reliance on electronics and no fan means its absolutely silent and the excellent insulation (which is why its wider and taller) realises power consumption is as low as can be achieved with good performance from the Danfoss BD50 compressor. So many manufacturers are reducing compressor capacity and significantly compromising performance of the latest model fridges. Anyway I thoroughly recommend the Bushman DC190. Cheers Tim

Working perfectly Annette. They are a great fridge. Sorry for the delay in getting back to you.
