So is this 3-phase system up and running and providing power to single-phase (120 to ground) circuits AND split-phase-requiring circuits (240 phase to phase)?
I would think that there would be no problem with the single-phase circuits (if there are any). But what about those split-phase circuits getting that lower voltage 208 volts not @ 180 degrees out of phase but 120 degrees? Sounds like kind of a scary experiment.. marco Friends: I feel sort of stupid asking this, but it has never come up for me before: I have inherited an off-grid install gone-wrong. The system is 208 three phase with Sunny Boys and Sunny Islands on a mini grid. It was designed as three phase. I presume this was to increase capability with stacked SMA inverters. Will the household appliances (small cooktop, booster pump, well pump) run as well on 208 as 240? I always do my research before wasting all of your time. The web delivered a lot of "forums" wherein opinions were expressed, but little hard data from bona fide professionals. I also did some calculations, see below. I downloaded a manual from a random electric range and saw it was specified as 240 or 208. Watts 4000 Volts 240 208 Amps 16.67 19.23 % Difference in amps 13.33% I am fairly comfortable that this is not an issue, but would like some confirmation. Thanks in advance. William
