Hi there,
So I've been given a 180w 36v solar panel and I would like to use it with a singular 12v battery..... There seem to be a lot of 12/24v MPPT controllers out there but I can't seem to find anything of a decent price that can handle 36v input and 12v output. My question is, can I use one of these 12/24v MPPT controllers with a 36v panel? I don't know if the voltage rated on the controller is specifically for the battery? I've been looking at controllers similar to this....

Failing that, would it be a sensible thing to use a 36v to 12v Stepdown Module like this one below?
http://www.ebay.co.uk/itm/200W-15A-1...AOSwHoFXqQw8in between my solar panel and my charge controller?
I don't really want to buy 3 batteries and run a 36v battery set up as my 180w panel won't be able to power it....and I'm hoping I don't have to buy a new panel instead, or spend a few hundred on a suitable charge controller.....
Any help would be greatly appreciated!
Thank you
