Pairing up the Eco-worthy 20a MPPT controller
Thanks to BFL confirming that the Eco-Worthy controller plays well when run with another controller, I felt pretty good about combining my two matched controllers. Each had one of the Bosch 245w mono ...

I was seeing 211w from each panel today and I figure they would put out around 35a at peak up there. I was seeing 212w and above 16a from the 230w poly last year. That was only under load though. Usually the batteries were in float long before noon. That's the other reason I don't think clipping would be a issue even up there.

The Eco-Ws offer advantages in that they can push 16-17a into the two banks or combined have the punch to make a difference on a larger bank that's down. The thing is I want to mount my nice pretty matched panels and don't room for a twin set of wires, switches, fuses, ect. It will be one controller for one bank.
I have also been removing the batteries from the rig when it's not in use and with a 8-D, that's a pain. With the system mounted, I can leave the batteries with the trailer. We get from 20 below to 105f here and without a remote temperature and voltage sensor I don't think the Eco-Ws are the best choice. They are great for fair weather camping though.
The other panels will go on craigslist but not until after I'm done with the mounting. Once I know 490w is enough, I can sell the other panels with a controller as a system and easily double or triple my money. I could keep the 230w system to augment but I'd really rather not.
