For a few months now this integration is practically useless for me and it seems for many people judging by all the recent issues. Data from SolarEdge is often delayed by a couple of hours so this integration zero outs the sensors. This integration is also the slowest I have with all the requests it makes.
So in home-assistant/core#146036 I'm adding an integration in core with similar functionality but uses statistics instead of sensors, and a single request to get the energy produced for all equipment over the last 7 days. Because it might take several months before it makes it to core, I created https://github.com/tronikos/solaredge_modules that you can install via HACS.
