Re: [RE-wrenches] Remote Sunny boy Monitoring
I used a Solar-Log with their wireless 485 solution to monitor a solar trailer about 500 feet away, through wall. It worked great.

Re: [RE-wrenches] Remote Sunny boy Monitoring
There is a company called Digi.com. they make a wireless bridge for the RS-485 protocol. Needs to be line of sight, but it will travel about 1000'. They are familiar with installers using their radios to communicate with our inverters, set up is pretty straight forward. I am looking for a part number. I have a couple of systems from my install days with these being used. I like Ryan's solution as well.

Re: [RE-wrenches] Remote Sunny boy Monitoring
If that is the case, there are some Ethernet bridges that will work. Depending on distance, you would need to buy a set with either adjustable power or know the exact range. I have a security camera set up I used a set on, had adjustable power setting. Works great. Adjusting the power adds bend to the signal. You might want to give digi a call, they have many solutions for things like this.

Re: [RE-wrenches] Remote Sunny boy Monitoring
i have set up wireless bridges for ip to remote locations and my experience with this has me leaning towards no dice william. these links run in the 2.3 gHz and up range which is line-of-sight only. trees will even attenuate the signal, so total blockage with the earth looks grim. have a great weekend everyone! todd On Friday, February 22, 2013 1:34pm, William Miller will...@millersolar.com said: Steve, Ryan: I don't quite have line of sight.

Re: [RE-wrenches] Remote Sunny boy Monitoring
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.
