Got the Combi set to -10 on 240 VAC, not for the freezer as that side is empty. But put some Xmas beers in the fridge side plus a temp gauge.

Last 3 days the fridge has been running at between 0.3C and 1.6C.

Great chilled beer in this hot weather.

In consideration of RR in Pomland, might I suggest a Travel Buddy Oven for your beer, lol. smile

I've had the Engel Combi on in the spare room over the last week via mains 240 VAC. Primarily to chill the Xmas "lemonade".

I set the fridge to -2C and empty in the freezer compartment. The fridge section has 1/2 beers and 1/2 cokes plus some choccy and flavoured milk in it.

I have an Engel wireless thermometer in the fridge section, which over the last week has maintained a temp range of 1.6 to 1.8 C. It's in a non airconditioned room which is currently at 24 C (even tho 33 outside). Room ambient has ranged from 20 C to 29 C over the last week, yesterday was a 40 C day outside.

Really happy with the 0.2 C consistency of the fridge temperature, even when opened for a short time for me to indulge once or twice a day.... smile

I've had the 15 lt Brass Monkey in similar circumstances and recorded a 5 C difference in max/min fridge temp. (Set to 2 C and ranged from 0 to 5)

I have the Engel set to 2-3 degrees because the temp guage on the Engel died a few years so i just check it occasionally with a digital thermometer. The Brass monkey has been tried a few times and cools very well.

Thing I didn't quite realise when I bought the combi is that when used as a combi with the divider, the temp gauge is what the freezer is set to. The divider panel insulates the fridge compartment from the sub zero temps and a fan operates to keep the fridge compartment cold but not frozen.

I did manage to do a quick temp reading of the fridge when I did the -5 & -10 freezer tests and it hovered between zero and 2 C (Engel was empty in those tests).

I guess the proof will be when I get it into the 4by and do my next trip. Only around 113 days to go, Covid notwithstanding, but not counting, lol. smile

Engel Combi obviously works the same as Waeco Dual Zone models . Same same with divider in thumbsup On long trips Waeco 80 used as freezer and short trips when not so much food required, used as fridge freezer. A 35 litre is always in vehicle run 24/7 in any case as a drink - dairy fridge, that just being because the climate here dictates it yikes

As this refers to solar, "Buyer Beware"

I'm looking at adding solar to my new van, did a search on Ebay and found this https://www.ebay.com.au/itm/29428972106 … ctupt=true

Key points on this item - It states it is a 250 W flexible panel. I was unable to find any stated amps output in the details. I did find its physical size 1080 x 710.
Here are some statistics to help explain

1. The power of the Sun at the Earth, per square metre is called the solar constant and is approximately 1370 watts per square metre (W/m2).
2. How much energy does 1 square meter of solar panel produce? - The standard solar panel has an input rate of around 1000 Watts/square meter, and the majority of solar panels available have around 15-20% efficiency. Therefore, 1 square meter would likely only produce around 150W in good sunlight. This is Maximum output

The above flexible panel is 0.77 square metres. Using the value in 2. the expected output would be no more than 115 W or between 5-6 amps max. I have a 110 W panel on my 4x4 roof, which is of a similar physical size and does output 5-6 amps.

Conclusion - In my opinion the advertised panel at the advertised physical size is either not 250 W or it is running at close to 200% efficiency.

Warranty explained ...........

Warranty - Some panels have a warranty specification annotated as 5/25, 10/25 or 5 etc. What does this mean?

Answer; In terms of a single figure, it is a product warranty of years on the product, may have more detail as to what the warranty is, re manufacture or output.

In terms of */** - This is usually - The first value is the manufacture or physical attribute warranty in years. In other words if it falls apart or has a physical fault.
The second figure is the warranty of solar output in years. Or, i.e. 100 W guaranteed for * years.

However, you need to look at the fine print - I've seen some panels @ 10/25 warranty, but the fine print explains "up to 90% output at 20 years and 80% at 25 years or similar. Why, solar panel output deteriorates over time.

Good quality glass panels have the 10/25 warranty, I've seen the exceptional odd panel at 25/25.
Medium quality would be 5/25.

There are some glass panels with just 5 years warranty, I would not use them. I won't state Supplier or Manufacturer, but they are known brands.

I've not seen any flexible panels with more than 5 years.

More........

Flexible panels -

I had 2 x 100W on my old van. They worked well for the first 5 years, but the output was dropping off in the last year or so. They were 7 years old.

I did some research on their construction -

There is a transparent film on the upper surface, it is in layers and deteriorates in UV (sunlight). The panels I used, had 6 layers and I noticed after around 18 months old the surface was mottled, rough and the film was "flaking off". I asked the supplier/designer why? This is how I know the above. Once that layer has "disappeared" The surface is similar to new. How quick this happens is dependent upon environment i.e. under cover when not in use, how much weather exposed to...... Once all layers have "gone" stand buy to replace. smile

Bottom line - The life span of a flexible panel is far less than a glass panel. A 100 W flexible is around 15-20% of the weight and 2-3mm thick compared to 30mm for a glass panel.

Conclusion - If you want to save weight/space then you compromise on life of use.

Personally still have not found anything that beats a fold out (moveable panel, relocated thru out the day) with a quality controller for harvest yield. thumbsup

I'm looking at a fixed panel/s that I make a stand for or a folding glass panel at this stage.

A 135 W fixed is approx 8 kg, a 140 W folding is 11.6 kg. Most folding panels come with a PWM controller and need a bypass, which I wouldn't use anyway. I've looked at a particular brand and the folding is twice the price.

I can't see 3.6 kg in hardware weight for legs, so I think I can do it in Ally for less weight.

Transport not an issue as whatever I get can go in the van until deployed. Although a similar size flexible is only 2kg, it would need more support to act as a standalone. Plus. I can't get past the 5 year (max I've found) warranty of flexible compared to 10/25 for a fixed I can use as a portable.

Now I have this 1800w doodad I am thinking of using Stainless Hinges and joining 2 or 3 of those 150's together Each one measures 135cm X 70cm, By using those hinges it will keep them together in one lump and being one piece it will give them some regidity, thumbsup

I'm looking at 2 x 100 W to 160 W, haven't decided yet. Their weight range is 7.5kg to 11.25kg. Not gonna join them as 15-22.5 kg is not a weight I want to handle through the door of a caravan.

The other aspect is that when detecting I'm not at the van, so I can leave one facing NNE and another NNW. Chained to the van to keep the "honest" people out their honest, lol.

I haven't done an ATM weigh yet, so no decision necessary yet. If too close that will be the only reason for going flexible. smile

Interesting observation re temperature.

I have several fridge temp gauges 1. My original wired Engel probe gauge, 2. An Ironman wireless gauge (used in my old 30lt Engel) and 3. An Engel wireless gauge, which I recently purchased.

The Engel 40 lt combi is set to 3 C, divider removed and as a fridge only. Being used as a drinks fridge on 240 VAC at the moment indoors.

The Engel and Ironman transmitters are next to each other and the wired probe within a couple of centimeters of them. Here are the temps;

Fridge set to 3 C (Stated as a guide only)
Engel Wireless 3.2 C (Range over the last 24 hours is 3.1 to 3.2)
Ironman Wireless 2.7 C (No max/min as only ambient and fridge are recorded)
Engel wired probe 0.8 C (Range over 24 hours -1.8 C to 0.8 C)

I would think the Engel wireless is the more accurate as that is the set temp of the fridge. The old wired probe looks like retirement is on the cards and the Ironman is pretty basic and reading low.
