Great solar controller. Combined with quality panels and and the "chase the sun" game with solar panels is over. The controller is a bit bigger than I expected but for me that just means they didn't compromise to fit it into a small box. Bring a reasonable size is probably why it's so cheap from a solid brand. Comes with 2 pre-wired Anderson plugs so setup is almost non-existent. I've just bought the compatible Bluetooth dongle (on sale). That way I can just hold my phone in front of my mate who's still pushing on with the crappy PWM that came with his panels
