Almost have my solar setup ready... just one problem

[ditryin]

I thought I finally had everything I needed to connect and get my first solar system going, but upon looking at the back of my solar panel the plug is a round/circular connector which can't be inserted into the charge controller that I have. I've attached a picture to this along with one of the components I have. Maybe someone knows of an adapter that I can buy that will fix this issue... but I'll also greatly appreciate any other advice on what to/not do when it comes to this type of solar system. Brand new newbie here :-)

Thanks swiftone and ireload for your help... guess I will order those and hopefully be up and running.... I do want to be able to plug in things such as laptops, small tv, charge phones, etc... and was thinking a surge protector would allow me to be worry free.... ohh and I just checked, my 60w solar panel is Acopower from Amazon that I paid $84 in 2017....yeah I’ve been piecing this system together for more than two years now :-( any last minute pieces of advice or any “make sure not to do this” statements?? :-)
