<p class="MsoNormal">Greetings Esteemed Wrenches,<u></u><u></u></p>
<p class="MsoNormal">We are building a 35.75kW project with (6) Power One 6000’s. The service is a 240 delta. The utility is requiring (late in the game) that if one leg of the service is lost, all inverters must shut down. Of course, we have two inverters
that do not shut down in that circumstance because they are only tied into the other two phases. SMA has a good (cheap) option to deal with this, SMA Power Balancers. With other inverters this can be accomplished by installing an ATS with an integrated controller
by programming in the unacceptable phase imbalance (expensive). Does anyone have experience with this requirement and/or have a good (cheaper) solution?<u></u><u></u></p>
<p class="MsoNormal">Thank you in advance!<u></u><u></u></p>
