Cold Beer - Second attempt

Back in 2012 I reported on the work I had done to install a 3 way fridge, and then I briefly reported on the issues we had had with smelling gas fumes whilst sleeping in her. This made me decide that I would never use a gas powered fridge and we removed the 3 way fridge 

Since then we have been using an electric cool box, but that has limitations and the performance is not very good and I have been wanting to get a decent front opening fridge installed for a while. Part of the project needed to be upgraded power and key to that was the new solar panel reported in the last posting

The issue is cost. Strangely the decent over landing type fridges are hugely expensive and it's taken a while to find one at a decent price. I finally tracked down a new Vitrifrigo c39i 12/24 and 240v capable unit at about half price with a minor cosmetic defect that would not even be seen once it was installed. 


You can just about see the minor damage on the panel at the bottom left of this picture. I checked that it was not touching any components on the inside and all was fine.



The first phase was to clear out the space and feed some wires from the 12v feed from the leisure battery 


Then I installed the 240v - 24v automatic converter



Finally, being a yorkshireman and tight with money, and because of the position inside a cupboard, instead of purchasing some expensive kit to fasten it in I used a couple of brackets fastened into the lower door fittings which were unused from another project


And added another couple of brackets fastened to a screw in the frame on the top of the fridge  to ensure that it is 100% firm in place


And we are good to go. I've tested it on the 240v/24v feed and from the 12v feed and all seems well.

The initial testing proved that the Danfoss compressor is as quiet as I had hoped. The final phase of this will be to add the split charge system, but in the mean time it's ready and it's time for some cold beer!

Do Land Rovers Dream of Electric Sheep Part II?

Maybe not, but I was dreaming of a better solar panel setup than the one that she arrived with which was a 10 watt panel installed in 2001 and probably not very efficient at all any more

The first thing to do was remove the old panel I have to admit that she looks a lot better without the panel on the top, but it will be coming back as you will see later


What we have purchased is an 80W flexible panel which fits exactly over the rigid panel that the old 10W panel was made into.  I would have like to go for a 100-150W panel, but this makes refitting an awful lot easier



I also bought a new Victron MPPT controller which feeds the leisure battery. This is more effciient than the old controller and being modern technology also has the capability of being linked to a smartphone app via bluetooth to give me some details on the charge profile of the battery. That's going to be a later addition when I find the bluetooth dongle at a reasonable price probably second hand.




I also bought a heavy duty cable with fuse to go from the controller to the leisure battery  and some solar panel cable to connect from the panel to the controller – I bought the shortest cable because all I really wanted was the connections because I was connecting this into the grey cable which was already in place through the roof.

The previous owner had run a cable with two black cores which was not clear once I had disconnected the old panel so Rhian helped me test with the circuit tester. The one I bought is designed to be cut in ½ so you need twice the length that you have between the panel connections and the controller. It was the same for me with the battery cable – I only needed  a couple of feet, but the spare will come in useful some time.


The new connections were all made in a waterproof housing which had grommets where the cable came through


But for "belt and braces" the whole connection box was sealed with flexible sealant as well


I would have liked to have virtually no loose wires, but that would have meant cutting the connections off the solar panel so I arranged them on the rear. it will mean there is spare cable if I need to adjust things so maybe not a bad thing


From this last picture you can see the old frame which was bolted to the roof-rack and to the blue light bracket on the roof. Once it was connected I took the cardboard I had temporarily put over the cells and things worked first time. I now have more reliable power and a basis of a modern system with reliable wiring which I need for the next 2 projects
