Have a question which I am sure someone here has already done. We have a use case where there is a PV inverter quite far away from Cerbo unit. What is the best choice for smartmeter (must be capable of external 5A CT’s) to either connect over network or we have the option to run CAT6/7 all the way to Cerbo.
We currently use some Carlo Gavazzi - EM 330 for other installations which work great but limited to RS to USB adaptor range.
Hello,
you can convert RS to ethernet and connect it to a transparent bridging (from few meters to many kilometers), and at the other side ethernet to RS.
Equipment A----RS–Ethernet—radio bridge 5,4 GHz — wave link ------ radio bridge 5,4 GHz—ethernet---- RS-------Equipment B
I use it fot industrial site. We encapsulate the RS frame in an Ethernet frame. You can cross 40 kms with big system, 6 kms with a small system for 300/500 bucks.
Yes, but how do you make it work at over 200m without zigbee adaptors? This doesn’t feature ethernet as far as I understand. We have two already in the setup connected through USB to RS adaptors. However, this third PV inverter is really far away.
Long distance smart meter - What are the best options?
Sorry if I’ve misunderstood your goal, but if you’re looking to establish a long-distance internet connection, I wanted to share an approach I’ve used that might be helpful, especially if you have a smart meter with an Ethernet connection that can connect to a switch.
Like this one.
While my particular setup involves a different scenario, the underlying principle remains the same. I’ve successfully used a fiber optic switch to create a network connection across a significant distance – in my case, a 500-meter run up my field – which provides me with internet access and access to my Cerbo GX etc.
I realize that a direct cable run might not be practical for your situation, but I wanted to offer this as a potentially viable solution based on my experience.
When running a CAT6/7 cable, which is shielded, is an option, you are not limited to ethernet connected active Equipment.
As you could use a RS45-to-analog-Terminal Adapter and run RS485 signal direct from an EM530 accross that distance, without active converters in between.
