Hi New Member here. Im about to fit a Solar Panel to our 2006 Rienza and would like to know if i can connect the Duo Charge Controller to both the Leisure and Vehicle Batteries via the Cables within the base of the Wardrobe or do i have to connect directly to the Batteries situated under the Drivers seat ? I would prefer to run the cables down into the Wardrobe just for tidiness sake and have the Charge Controller above the 12v Switch panel on the outside of the Wardrobe.
Is there a Wiring diagram available for the Wardrobe cabling?
Any help would be much appreciated.

There is a basic wiring diagram in the Rienza hand book but it’s not clear we’re you could tap into for the solar controler.
As I have said in another post the wiring from the solar panel comes into the living area above the left rear corner of the Luton. It’s then fed behind the trim on the near side door pillar to the controller under the passenger seat were the second leisure battery is fitted. Cables are then fed under the floor panel between the seats to the leisure battery under the drivers seat. 
If you only have one leisure battery as oringional build I would consider bringing the cables down the off side door pillar and fit the controller to the battery box. 
The solar panel and second leisure battery were fitted before we bought our Rienza but it seems to be professionally fitted.  As with any vehicle wiring it should be properly fitted with safety in mind and not detract from the rest of the build quality especially with a motorhome. 
The original controller was only a basic one without a means to charge the vehicle battery. Following advice from the forum I fitted a battery master. A very simple fit that has assured the vehicle battery is kept charged from the solar panel.

Thank you Dave for your info. I am now considering coming onto the Van through the offside Cubby above and to the rear of the Drivers seat and mounting a Master cut off switch and Charge Controller to the outside of the Cubby and running the cables down the wall into the under seat Battery area.

Over six years since I traded in my Rienza, but when I first purchased it I wanted a solar panel. The panel was mounted on top of the roof bars near the front but avoiding roof vents, (memory is not perfect). It was a 100 watt panel. The cabling was brought down into the wardrobe right side (wall nearest the rear of van) above the top shelf, so charging lights could be observed, this was where a basic controller was mounted. The cables must have run to the battery under the drivers seat. I had the installation done by a local independent Motorhome service specialist, so how he ran the cables past the bathroom I cannot advise on. I seem to recall that the charge only went to the leisure battery

The benefit of mounting the panel onto the roof bars meant the mounting was very secure using U bolts. There were no further holes on the roof (cable duct excepted), the panel could allow circulation of cool air easily and I could get a brush under the panel during the periodic roof wash.

I'm not familiar ith the Rienza but I suspect it may be  somewhat similar with a Nuevo as regards wiring running in trunking through the wardrobe.  On my Nuevo I had a panel mounted on roof with wiring brought into the wardrobe. The fitter wired it into the existing wiring in the trunking. It was only a single controller but he wired a battery master in there as well so both batteries were kept charged.  No wiring went direct to the batteries,  all was spliced into existing wiring in the wardrobe. This may be an alternative to consider.

I'm not familiar with the Rienza, but thought I'd mention that when Roadpro fitted a solar panel to our 2006 Ford Transit-based Pollensa they didn't need to fit a battery master (as originally quoted) as they found that the Ford wiring between the batteries obviated the need. Therefore answers to your query may vary depending on the base vehicle and its year of manufacture.

i wasnt sure about the way Ford wired the two batteries under the drivers seat but fitting the battery master seems to have kept the vehicle battery at the same level as the leisure battery. Before the leisure battery always had a slightly higher voltage. 
I can see Autosleepers logic of using the second Transit battery as the leisure battery but the combination of Ford and Autopsleeper wiring is a bit of a rats nest.
Also some of the electrics switch the earth instead of the live. This was the case when my fridge stopped working with the engine running. I had trapped a thin black wire for the fridge relay under the vehicle battery when I changed it.

I'm not entirely sure how they're wired. Roadpro said that when starting the engine both batteries were brought into play to provide more power - there was some kind of link that meant both were used. I have no idea how this works. Because of this link Roadpro said it wasn't necessary to fit a battery master as there was already a connection between them. As well as the solar panel and controller they fitted a Votronic battery computer with LCD display, and this shows the solar panel is charging both batteries.  This is about the limit of my knowledge, beyond this I'm in the dark, although I definitely agree with you that it's "a bit of a rat's nest."

Not wanting to detract from the original post but a I will just add to what has been said about fitting a battery master and what I understand about the Ford Transit battery system. 
Because Ford fitted two batteries as standard, one starting and one auxiliary, the charging system will have a split charging relay to charge both batteries when the engine is running. By fitting the battery master the solar panel will top up both batteries when we are stationary. 
I have had dealings with duel battery starting and charging in the past. Twelve volt run and twenty four volt starting. Our electricians used to hide if they got wind of problems because it involved strange relays and control boxes.

Hi Dave, I'm not sure how it all works, but our solar panel definitely charges both the leisure and vehicle batteries without using a battery master. The Votronic display can be toggled to show the state of charge of either of the batteries. We had the system fitted specifically to charge both batteries while the van is in storage as it's such a hassle removing both batteries to charge them at home over the winter.  Originally Roadpro quoted for a battery master as part of the installation, then discovered it wasn't needed.  So far the system has worked well and kept both batteries at 12.4v or higher even in the darkest days of winter.
