Ironically as I was looking through my TED 5000 package this thread came through.
I am looking to use the TED for data logging for an off grid project, and plan on connecting a computer directly to the Gateway, as the client doesn't have internet access. I hope to use the information for system sizing. Have any of you found the logging to be unreliable?? There is no display involved, and loads are powered by a bit of solar, but mostly generator.
