HI August, Thanks for the note. I'm solely interested because of the voltage window - I always struggle around the 3.5-4.5 kW range for string inverters, particularly with SMA which is my general preference. I have defaulted to Enphase in some cases, but typically shy away from them because lack of trust and higher cost (though the Enlighten Monitoring is certainly an eye-catcher - time waster - for the clients).
