I wonder if anybody has some hints on where to get the most of the components? - Instead of ordering at many different places and pay postage at each shop, would it be nicer to order at a few shops and save postage.
Any recommendations?..
I always order at mouser.com. As soon as the order is >50 € (which it will be for sure for the charge controller), shipping is free. And the parts arrive in Germany within 2 working days. The only part they will not have is the large inductor, which is from Feryster.
TME has the same inductors as used in the charge controller with a slightly different winding (for vertical instead of horizontal soldering). So they could be used after the winding is moved a bit. And they might also have the rest of the components on stock.
