The Eco-Worthy is a good controller for a single 24v panel but it has a limit of 42V Voc total for all panels on it. So using it with two 12v panels in series at 22voc each is too much.
The Tracer MPPT has a Voc limit of 100v and you can get them in higher sizes than just 20amp too. They cost a little more than the Eco-W at about $140. It has a fixed charging profile, not adjustable. It gets the batts to 14.6v, holds that for two hours, and then drops to 13.8v till dark. This charging profile worked well for me but YMMV. (Same one as in the LandStar I had)
Yes you can parallel controllers, no problem . JiminDenver has three Eco-Ws but on three 24v panels so each controller is under that 42v Voc limit.
