Hi William, I have successfully used this product below on a few installs without line of sight, trees, hills, etc in the way approx 1 km span doing exactly what you are asking for - wireless RS485. It costs more than WiFi bridges, but it also works!
http://www.bb-elec.com/Products/Wireless-Cellular/Radio-Modems/Industrial-Grade-Radio-Modems.aspx Specifically, the LR-KIT, at 900MHz is better for marginal sites, coupled with external antennas and quality cable. Don't skimp! I used a Yagi antenna on the webbox side to transmit, with an omni antenna on the receiving end. Line them up as best you can and spend a bit of time adjusting until there's a signal. Once we got the units talking it's been 100% uptime for at least 2 years now. This company has all sorts of neat network products that I have been using for over a decade. Amazingly solid industrial quality gear. I believe they have a wireless AC relay solution as well I saw people asking in another thread. I never ended up deploying, but they had an easy off-the-shelf solution for a wireless gen start signal retrofit where pulling cable wasn't going to happen.

Here is what I have learned: The main problem is that the Sunny Boy is remote from the house and there is no signal conduit. There are any number of monitors that can hard wire to the Sunny Boy, usually with an RS485 connection. Without a hardwire path that solution is not so easy. Apparently I need to asses the viability of a wireless RS485 system. I am wondering: 1. Do I understand the above scenario correctly? 2. Do any of you have any experience with wireless 485 systems? Thanks again for all of the help.
