>I'd like to pitch in my experiences with the TED -- as others have pointed >out, it leaves some things to be desired. > >I have a client with a TED 5000 -- Holt Kelly from this list is the installer >-- and there were some limitations that haven't been resolved by Energy, Inc. > >The show-stopper for my client is that they have a hybrid system with a >SB6000U and GVFX3648. The customer wanted to monitor the production of both >inverters. The client has three CTs installed in their main panel -- one pair >around the feeders from the meter, another pair for the SB6000U and a >singleton for the GVFX3648. > >The problem is that only the first CT is configured to record bi-directional >power. The result is that the GVFX3648 always shows up as a load, regardless >of direction of current flow. The only solution to this limitation, right >now, is to configure that CT as a "Stand-alone" system. It turns out that the >way their GUI displays the data, the SB6000's CT also needed to be configured >as stand-alone system. > >In terms of customer support, the people I spoke to (for two hours) do not >understand renewable energy systems, and do not listen. The client has 8KW DC >total and the system was exporting a fair amount of that. The CTs were >misconfigured (see earlier) and customer service didn't understand that my >client was NOT using 4KW or whatever. > >The TED 5000 is okay in a single CT configuration. They've promised firmware >updates that will make it work better with inverters, but I'd hold out before >installing in a configuration that =required= that functionality. In my >client's case, they wanted to know system net (import / export), and the other >two CT values are less important. >-- >Julie Haugh >Senior Design Engineer >greenHouse Computers, LLC // jfh at greenhousepc.com // greenHousePC on Skype
