inexpensive MPPT controller

Thanks for the info.

$170 for 10 amp is inexpensive ?
I have a brand new 20 amp MPPT still in the box I bought for $18 bucks. Does it work ?? Beats me, but I assume it does. And if I install an $8 digital readout amp/volt combo meter in it, I'd have a $150 controller ??

The guy I got the 245w panels from had a slew of 180w panels tht may have done well with the 10a controller. I still think the Eco-worthy at $102 shipped is a better deal. More adjustable too from the looks of it. It is good to have options.

Mine cost $15 on eBay...
