<b><u>10 seconds</u></b>?  I’ve never seen a string inverter’s DC input terminals drop that quickly, and I’m especially curious to know how the string inverter manufacturers are going to cope with this, or if Midnite has anything to help deenergize the capacitors.<o:p></o:p></span></p>

 to disconnect the conductors from the capacitors (i.e., at the inverter) and another to disconnect the conductors from the array (i.e., at the array)?  Doesn’t seem very “rapid”, but 690.12 isn’t very specific.<o:p></o:p></span></p>
