I don't have anything in terms of advice on the Tri-Power, but I have done microinverters on straight 208V three-phase and also 480V with a step-down transformer. While there are more potential points of failure, future service is straightforward. There are lots of capable people who can swap a mic

Hi Wrenchers, I am considering using 8 SMA Tri-power Inverters for a project with a 3 phase 208V Grid which means I have to add a step down transformer (480V to 208V). I am comparing this option to a central inverter.I have done many of the central inverter systems at the 208V but have ye
