Hedges: I was at a 'be prepared' (emergency prep) convention and a solar engineer had a both. Very friendly and knowledgeable guy willing to offer advise. He cautioned me on using the solar trailer on my current setup based on my GT solaredge inverters. According to him, the Sunny Island inverters are able to discern when power should be shed to home, but that the solaredge inverters don't have a ground, nor any way to communicate to the SI inverters. Because of that, I would need a very large battery bank to store excess storage because my PV on a Sunny day would continue to generate power and the Solaredge inverters are not intelligent enough to say 'stop, no more power, we're all full down here'. That wouldn't be an issue if the grid was accepting net zero backfeeding, but if the grid was down and backfeeding was shutoff, I could theoretically go boom in that setup or at a minimum throw a breaker. He said they way around it would be to get hybrid inverters in the place of my solaredge or a SunnyBoy setup that would easily communicate with the SI inverters. I couldn't tell if he just wanted to sell me on the new equipment and install fee or if he was right and I need to abandon my SolarEdge GT Inverters. Are you aware of the lack of communication between SolarEdge and SI?
