I've got a 3-phase 12000XP off-grid system and my main gripe is that the eg4 monitor web interface doesn't support 3-phase systems very well. Paging through the different inverters to get an idea of what's going on is a pain. It would be nice for the default view to be an aggregate chart with all three phases from all inverters stacked up to give me a better picture of whether the legs are balanced appropriately or if there's a problem somewhere. It would also be nice to be able to name the inverters so I don't have to remember which dongle ID corresponds to which inverter.
