The system is working OK but production is a bit low. There may be other factors and I am looking into those too but I want to sort out this one issue: I am not too familiar with 3-phase and when I ask SolarEdge about best way to connect to a 3-Ph delta, they advise to stay away from the stinger and connect a 1-ph inverter to L1 & L2 only, and that has worked out fine. However, This system has a 3-ph inverter and L1 to L2 is reading about 215 volts from the utility. L1 to L3 is the same and L2 to L3 is also about 215 volts. Perhaps this is a 3-Ph WYE with just a higher than typical voltage coming from the utility t-former. My thought here is that maybe the 3-ph inverters are only providing 2/3 power back to the utility, or if there's some way to get to 240v L-L. The existing loads are serviced by both 2-pole and 3-pole breakers but everything is pretty much 1-phase I believe. I'm wondering if I should consider reconfiguring the system with 1-Ph inverters tied in to only 2 of the utility legs. I asked SolarEdge weeks ago but getting nothing from them. Any thoughts?
