I took a chance on the Eco-worthy 20a because I was able to see inside on a utube video. I'm not only thrilled, I'd buy another if I wanted to run my second panel. Both systems together would max over 30a tracking.
As it is I had no need of the generator for charging even with a flat panel and the clouds rolling in around noon. We went from turn it off, scrimp and save the battery to hey Hun, lets get a 2000w inverter and a satellite.
There is a 40a controller with all the bells and whistles for around $250 that I'd try if my panels were a matched set. It's a risk but so was the Eco-worthy.
