Most controllers have 3 sets of terminals, panel, charge to battery and a load pair which are connected to the internal lvd circuit so that the load doesn't flatten the battery. The controller is built for drawing the load through hence 10A/20A/30A etc. rating which applies to the load just as much as the output of your panels.

This is the controller that was attached to my folding panel. I am not using it as I have a plug wired in the cabinet that goes to my Pro Star controller.

Down to the rear hing and under the canvas, through the upper bed, down between the window and wardrobe, through the join in the wardrobe outer skin, through the bottom of the wardrobe and over the water tank and into the small lower cupboard next to it. This is where the leisures battery on mine are.

The only internal holes I had to make were the two 6mm holes coming through the upper bed.

That looks great Tom. What are the roof bars? And the panel?

Where form Keith?

I bought another from eBay. Turned out to be the same company, using a different name and selling at a different price. So I have now paid for two and they are not available.

I had a similar situation with a completely different product a couple of years ago. I turned the extra £10 refund for +ve feedback down and forwarded the email to Ebay. The seller was removed shortly after that :shock:

They are more likely to get positive feedback if they promptly repaid in full and apologized. Raise a dispute and get your money back in full and leave them negative feedback for trying to rip you off. I have no compunction about raising the matter with eBay with sharp practices - I caught out a German who had his mate shill bidding on some items I was after, I got him banned.

Not a Westy clearly (it's a Viking roof), but my 100W panel arrived yesterday so I just had to throw it over the pop top this morning to get a feel for what it can do. At almost exactly 9am it's making almost exactly 1A at 21.5V (open circuit). In theory, at 95% conversion efficiency, an MPPT controller will turn that into 1.4A at 14.5V charging voltage. Not bad for watery February sun.

Laid flat in the sun on Monday my panel was producing 1.72A with the roof up it increased to 2.86A. This wasn't pointed directly at the sun.

Hehe - snap!

Just waiting for my meters to arrive from China to finish off the install. It's in and working, but I can't see how much it's making until I add my ammeters.
