I worked on the fan and other things over the holidays when I had time. The first picture shows the fan as seen from the inside of the van.
The second pictures shows how it would look with the garnish in place. The roof is much thicker than I thought. It almost wasn't deep enough.
This picture shows it bolted down from the outside.
I put a vent cover on it so that it could be used at all times, even in the rain. I figured it isn't much use if you can't use it when you need it. Definitely gives it a distinctive look.
At the point in the next picture it should have been done, but I decided to adapt it a little bit. Looked great for about a day.
The fantastic fan that I installed did not have the thermostat option. I would have liked it to have it, but it was just too good of a deal to pass up. I had ordered a temperature controller for a different fan. When it got here, I realized it would probably do a good job for this fan as well. The first step was to take off the fan garnish and measure out and cut a hole for the controller. It isn't very big.
A little simple wiring and it was mounted in the hole.
I think this is actually a better option. It can be set on a heating or cooling mode. It will normally be on a cooling mode, which will turn on the fan as needed when the van gets too warm. This would be mainly in exhaust mode. You can set how long it will run before it shuts down and how much of a tolerance you want to set before it starts back up again.
In heat mode, it would draw in warmer air from outside. If it has been a really cool night, it could be set to draw in warmer air as the day gets warmer and thus keep the inside warmer automatically.
The only down side is that the temperature reading was only available in Celsius. It's not a big deal. I will make a chart to sit on the wall next to the controller so I can quickly set it.
I got the upgraded charge controller and the other two solar panels on Christmas Eve. It was quite the adventure to get them. I ordered them directly from the manufacturer in China. Ended up being a good deal, but it was a bit of extra work. I posted about it under the electrical area of the forum if you're interested in the story.
The first two pictures are the charge controller and the lcd panel that came with it. It is a 60 amp controller. It should easily be able to handle what the panels can put out.
The next picture shows the new panels. They are rated at 190 watts each. I already have two 158 watt panels, so the total possible output would be around 700 watts.
The first thing I did was install the new charge controller. I knew I would have to move the panels that were already installed, but I wanted to verify the charge controller was working fine before I did that. The first picture shows it installed in place of the original controller.
The second picture shows the display when active. It goes dark after a few minutes to save power. It is in standby mode in the picture because it was after dark when I took the picture. You can make quite a few adjustments between the controller and lcd panel.
The next step was to add the new panels to the roof. This is more complex than it sounds. I wanted to maximize roof usage, so there is very little extra room. In order for them to fit I would have to remove the original panels and remount them all in a different direction. This proved to be more challenging than I thought it would be as there is not much room under the panels to work with. The first picture shows it from a ground level.
In the second picture you can see it from above. The panels effectively cover the majority of the roof. It's not quite completely done in these pictures. At this point, the bigger panels on the driver's side are completely bolted down and done. I had just finished the wiring so I could test it all out. The panels were putting out about 36 volts total at around 10 amps later in the afternoon. Hopefully I can see it under full load today and get a good feel for how much it can produce.
It is winter and the sun is fairly low on the horizon with a few trees that partially shade the panels where it is sitting as I work on it. All in all, the power it was making yesterday was a good indicator of what it should be able to do.
