Yesterday, I was able to upload firmware to the Mate 3s, and the GS4048
and program it for AC coupling. I did not realize a firmware update
would shut down the inverter (makes sense that it does), so that was a
bit of a surprise, but all in all it went very well. The Mate3s
firmware was out of date by almost a year, and that did not allow the
inverter firmware and its AC coupling capability to be set. Once I
update the Mate3s, I was able to specify AC coupling. Thanks for all the
suggestions and I know I will be able to use them in other situations.
