Works with Truma SDC12 duo MPPT
Works fine and tells us when we are charging - helped us realise that we need hookup in the winter, the panels aren't generating enough to keep battery topped up.

There is a 20amp fuse inside
I have used This controller for 2years some how one day it stopped working. The solar panel indicator was flashing ( the controller is waiting for a solar panel to be connected) .I thought I'd investigate so I removed the top 2 screws on both the front and back this released the top, and to my surprise and delight the 20amp standard car fuse had blown. It was difficult to pull out to replace, I installed a new fuse and the controller instantly started working...yes.I would think the fuse is a safety feature as my battery sides are swollen and must have caused a power surge back to the controller.The controller has worked flawlessly from the first day it was fitted and is still working flawlessly today.I also have the blue tooth option and this works flawlessly too .I would definitely recommend this unit too anyone. Although if you can afford it go for the next model up for better 2nd battery charging.

Simple to install and good value
I was a little suspicious of the low price, but it's actually really good. I added the bluetooth dongle and the simple app connected without fuss and tracks all info for the last 10 days, while showing real time data.I've used it for a week now and am very pleased with this item.Highly recommended.
