Can you see that box protruding from the left side of the fridge vent cap where the wire is going in?

I’ve been thinking about adding a solar panel and trying to figure out how to daisy chain it into my existing system. Research brought me across ‘combiner boxes’, which take the connections from solar panels, combine the current, and send it all to the charge controller. So once the original panel is installed with the controller and wiring, adding future panels is just a matter of plugging them into the controller box.

Damn, why didn’t AM Solar sell me one of those? 🙁 Or maybe they did? I should go up on the roof and check! Oh, wait, I took pictures of my installation. Ah ha! Oh, wait. That’s the vent cover. Hmm… I’m not sure. I need to get on the roof after all. No, stupid. They gave you a detailed invoice! Check the invoice and sure enough, I was billed for a ‘refer C-box.’

So adding a new solar panel will just be a matter of screwing and Dicoring it to the roof and plugging it into the combiner box! The job doesn’t seem as scary now! And I’m further motivated to buy from AM Solar, even if I won’t get the lowest price, since I’ll know for sure I have the right connections.
