2017 Solar Upgrade

It may or may not be apparent that we spend a considerable amount of time away in the camper. I would estimate that we are away two months of the year, if not more, and since fitting solar over two years ago ( documented here) , it has made the time in the van a lot more flexible. We seldom used electric hook up (EHU), and this has saved us enough cash to pay for the original installation with money to spare. However, after some unreliability cause as a result of the original batteries failing in the last few weeks, its time to make some decisions about where we go next.

I have been really happy with the original install, and if we had not had any issues I am sure we would have just carried on the way we have been. The limited size of the battery compartment behind the front seats means battery options are very limited. On top of this, any battery that will fit the aperture was never really designed to provide consistent power to devices like fridges etc during lengthy periods away. The more I researched it the more convinced I was that the original leisure batteries could only really last a couple of years in my configuration.  Deep cycle batteries are designed for continual usage of persistant charge and drain, but these are always going to be higher, if not longer or wider than the stock compartment would ever allow. So with this in mind, if I was going to push forward with my next generation solar solution, it was inevitable that the batteries were going to have to me stored elsewhere.

Once I got my head round this I felt like my hands had been untied! I started stripping out the contents of the cupboards so I could really get to grips with the space I had available. I soon decided that the small lower cupboard next to the fridge was probably the most suitable location for the batteries, and the cupboard above that would be for the fuse box.

Cupboard chosen for batteries is lower left of this photo.

The small lower cupboard had a divider panel in which essentially separated the storage side from some of the consumer electrics ( RCD breaker switch, power socket and EHU and associated cabling and junction box ), so this needed to come out to free up some space.

This is a photo of the lower cupboard with the divider removed. The battery is just for reference.

It soon became apparent that the RCD and some of the cabling would also have to relocated if I wanted to run a two battery setup. Once the cupboard was clear enough to get some measurements we looked online for the largest AGM battery that would fit the space and ordered it.

AGM Leisure, Power Plus Type 120 battery

So I set to fabricating the base plate for the batteries out of a sheet of OSB I had lying around.

I wanted to do the whole install as sympathetically as possible, so drilling holes or applying fixings to anything that was an original component of the van would only be done as a last resort. Making a base plate for the batteries gave me an element of flexibility to be able to use this as a fixing platform for securing the batteries in place. It was cut just big enough to snugly fit in the base of the lower cupboard. From a previous project I had an excessive amount of thick black rubber matting, so I decided to place this on each side to create a non slip base.

This picture shows both the lower cupboard divider and the upper shelf which are going to be put into storage in a safe place in case the process needs to be reversed.

Left is lower cupboard divider. Right upper cupboard shelf which forms the cupboard base.

Due to the fact the lower cupboard is going to be filled with batteries, and the installation of them can only be achieved effectively with access via the upper cupboard, placing the shelf back into its location afterwards will not be achievable in one piece. In one piece the shelf has to be dropped in at an angle to the lower cupboard space and juggled up into position. On top of this It will need an additional hole cutting in the shelf to allow access for cabling. So this is my reason for fabricating a new shelf.

I chose to use 5mm plywood. This needed cutting to shape and bonding one on top of the other. Reason for not using 10mm in the first place is that I needed to create a lip that forms a resting point along one edge.

Here it can be seen in place.

And here after the cut is applied and the components are painted.

Next is the relocation of the RCD and fuse box. I used a piece of 8mm plywood board cut to size for the back plate. I used two stainless M8 bolts to act as fixings for the RCD onto the back plane. The fuse box uses two self tapping screws. 

After some head scratching i fabricated the rest of the components to build up the casing for the RCD unit.

These were then painted in grey enamel to match the cupboard base. 

It can be seen here offered into location. Still some way to go yet though. 

So I have the new battery and have pretty much fleshed out locations for all of the components in my system. The original live wiring that goes to the old leisure battery location will need feeding back to the new battery location in the lower cupboard and connected to the battery.

My original solar charge controller was a PWM (Pulse Width Modulation) unit. It had feeds for two batteries and came with a LCD display. However, it is fairly basic in its technology and only really acts as a switch filtering power to the batteries when the panels receive sunlight, and stopping drain at night.

During my recent research into solar controllers I have come to the conclusion that I would probably benefit from moving onto the more expensive MPPT (Maximum Power Point Tracking).  The MPPT harnesses the solar energy before sending it to the batteries much more effectively. The increase in power to the batteries can be 30% more efficient if figures are to be believed. Along with this efficiency, they seem to have a lot more intelligence and diagnostics available to draw from this type of solar controller. Monitoring using a smartphone via the installed application gives lots of analytics. 

So in the next few days I will be placing an order for the above Victron Energy 100/20 , 20 amp solar charge controller with built in Bluetooth. This can be monitored by a phone app when within Bluetooth range. This will be positioned in the original leisure battery location behind the drivers seat. So I am looking forward to getting the rest of wiring completed ready for our two week break in September.  On that note I will conclude for now by saying I will add more to this particular BLOG post as I move forward with the rest of the install to hopefully provide complete a guide to anybody that may be considering going down a similar route.

gearbox progress

A little progress on the gearbox…Due to issues with a batch of faulty parts, the gearbox wasn’t ready for my September holiday. As has been covered in a previous post we managed to get away thanks to a friend lending me a box. Ironically, I received an email stating my gearbox was ready the first day of our three week break. Suffice to say I was not really in any positing to collect until the end of September where it sat in my garage until a couple of days ago.

The box build spec changed from standard to include a 4.14 final drive,  stronger 4 pinion differential and new differential bearings. This should compliment my new, more powerful AAZ engine with longer gears throughout and a higher cruising top speed.

Knowing that the gear boxes are prone to corrosion due to its position underneath the camper in front of the engine, my intention was to paint the casings before fitting the box. I thought about etch primer (the yellow stuff that comes out of an aerosol can), but decided to try Hammerite primer on a small section of the alloy to see how well it adhered. After a couple of days I checked and it seemed to have keyed on really well, so the rest of the box was painted.

I am in no great rush to have the box fitted, and the reality is it’s probably going to sit in my garage for the next  6 month until my van is booked in for a service at Brickwerks. I’ll get them to fit it then 🙂 . Hammerite takes a good few weeks to cure, after which I will paint again with a mid grey engine enamel.


Thermal Screens

Pitched Up and ready to hit the city

I have had a couple of people ask me about the thermal screens I use on my van (seen above on both the window and pop top). Both of these get used on almost every camp over oblivious to the time of year or temperature for reasons explained below.

The pop top roof canvas was purchased directly from Paucer

The obvious reason for buying the screen initially was to try and retain the heat from inside of the van during cold weather. However, we do find that it reduces the noise slightly if camped in busy locations, along with reducing buffeting sounds when windy, and the sound of rain on the canvas. During summer it reduces the amount of light in the van which can be helpful when the sun starts to rise at 5am.  After all, who wants to be woken up at the crack of dawn when your on your hols? 🙂

All T3 / T25s have glass window screens and door glass so a thermal wrap is a must if you want to stand any chance of eliminating condensation from the cab area of your van. The Silver Screen was an expensive purchase in comparison to the alternatives that are on offer from the likes of Just Campers etc. At over £100 it was twice as much, but my purchase is still as good today, as the day I brought it. You can definitely see the difference in the thickness of the quilting and the old saying ‘you get what you pay for’ certainly rings true here.  The screen cover was brought directly from Silver Screens ( ).

Big Mirror refurb

The Atlantic was one of the few vans that came with big mirrors as standard. These were always colour coded from factory in one of three available colours. White, calypso green or red. My van on the other hand came with mat black mirrors.

black mirrors

This didn’t particularly bother me as I always knew I would get round to painting them at some point. It’s just never really been a priority, what with the van getting plenty of use during both winter and summer. However, my current situation means Wolfgang is off the road for the time being, so this became an opportunity….(always need a positive spin with these vans ?)

Unfortunately, its not quite as simple as just unscrewing them via the visible screws on the door bracket. They are heated and servo adjustable from a switch module on the left hand, drivers door. This means that the door cards have to come out on both sides. The fallowing video is a guide to removing the door cards for anybody that may need to perform this process: (courtesy of Van-Again on YouTube)

Below is my door after card removal:

Then  electrical ‘block’ connector needs disconnecting and stripping….

after which the wires can then be passed through the small cable aperture to mirror.

Cable entry / exit hole in door

Its not massively difficult, but a little more involved than one would first imagine.

Then the mirrors need stripping into their basic components before paint.  Separating the bracket from the mirror was done using a pair of long nosed pliers . There is large slotted nut (1 in below image) that winds up against a perspex bush (2 in below image) and spring. Again, not the easiest thing to do especially if the nut hasn’t been removed for a number of years.

Mirror brackets removed

The mirror glass also needs to be removed. If you look closely in between the glass and the outer casing you can just see the two tabs sticking out on either side. Not particularly clear under instruction exactly how these hold the mirror in, but with a couple of knives carefully slotted down the side, and an up movement on one side, and down on the other, the mirror pulls free of the servo unit.

Wires connected to mirror are for heated / defrost function during cold weather

From the picture above I was slightly surprised to see the original colour inside the casing. I did strip one of the mirrors down even further in the hope that I could just send the plastics and bracket away for spraying, but realized the connectors on the end of the loom wouldn’t go through the hole in the bottom of the mirror. This meant they must have been crimped on after they were thread out of the aperture during construction at the factory. I wasn’t willing to cut them off and re connect after paint, so I left the whole servo assembly in the mirror. You can see more clearly the original paint in the photo below.

Original paint in mirror.

I can only assume that the original external paint must have gotten scratched, chipped or dis-couloured to the point where a previous owner decided to take matters into his own hands with a DIY spray-job using a can of mat black paint.

So this was just about as far as I could take it. I was considering getting a few rattle cans made up and having a go at painting them myself. However, these wouldn’t have been cheap, and these on top of the extra wet-n-dry emery paper and primer, would have meant that I probably wouldn’t be saving a great deal against the cost of a professional paint shop. So the paint was purchased and both mirrors and paint were taken to a body shop I had used previously to have my Fiamma Box painted.

Two Days later I collected and I must admit I am pretty happy with the results . I just need to build them up and pop them back on the van 🙂

Seeing Red

So my van has gearbox issues! But no reason to stop chipping away at the things that have annoyed me until that can be fixed. Basically, the gaps in my wheels aren’t massive because of the style of alloy, but annoying all the same to see the rusty drum behind. So yesterday / today I jacked the van up, popped the wheel off and set to realizing my goal. To paint the drum red.

Anyways, one thing leads to another, and before you know it (5 hours later actually), I’ve washed away all the mud, painted the trailing arms and stone chipped the wheel arch.

The finished article:

The replacement gearbox should arrive on Tuesday, along with new clutch and slave cylinder from Brickwerks (due to be fitted on Friday locally). Nothing like cutting it fine. We should be on the ferry for our Euro trip just over a week later. Lets hope there are no issues with the replacement box!?
