operate independently, each inverter on one 120 vac leg of the 208 three phase.
I assume they can’t sync because any two legs of the three phase are not
the required 180 degrees out of phase.<o:p></o:p></span></p>

font-family:"Arial","sans-serif"'>Hi Gang,<br>
<br>
I have a problem. We are installing a gridtie PV system with 2 battery-based
inverters for 240V. The service coming in to the condo is 120/208 split-phase
fed from 3-phase 208 in main building. The master inverter pickups up L1 but
the slave inverter will not sync. What am I missing?<br>
<br>
Thanks and Happy New Year to all!<o:p></o:p></span></p>
