I was thinking in terms of using the Envoy-S together with the AC Battery to limit power export limiting, but based on your comment I can see that it really means limiting export power IN THE ABSENCE OF ANY AC BATTERIES. That could absolutely have value, particularly in locations where there is little or no value in exporting. In my case, I could have used this when I first turned on my system since my meter charged me for electricity flowing in EITHER direction. In that case, exporting electricity had NEGATIVE value, so I would have utilized this feature right away!
It is a bit interesting that there is no mention of this capability included on the datasheet for the S-series microinverters. Further, since I expect that the fourth-generation microinverters almost certainly employ digital control algorithms that they could be updated via firmware to provide the same feature. Assumedly Enphase has decided that it is not worth the engineering effort to implement such a feature on the older units.
