Most of my customers want cheap, and they get what they pay.
I only use and fit these, easy to use, easy to read at a glance. I personally have the 30amp one on my caravan it controls 800 watts of panels 4 x 100 amp hour batterys, and I can run my 3 way fridge on solar all day, it is basically install and forget This is the BEST
