Chapter - Limitations
Section - Full ESS is not supported
Content - It is not yet known if the current hardware revision will be able to support grid codes, or ESS, via a firmware update in the future." - Multi RS manual
The purpose of that conditional sentence was that there was potential that it would be possible with the current hardware version, but also potential that it would not be possible and require a hardware revision.
I am a native English speaker, to me still in spite of the criticism in this thread that sentence is clear, complete and as accurate as I could make it at the time.
I had no agenda to over-sell the Multi RS on features it didn’t yet support. Only to answer questions that I was getting as efficiently as possible with what we knew at the time.
We were working on ESS support, but we didn’t know what changes would be required yet (if any), either in hardware or firmware.
