The CC has been putting in extra watts to keep the batteries at its absorb voltage, the load is suddenly off, and it can\u2019t react fast enough causing a short voltage spike ( I call it a bounce). </div><div class=""><br class=""></div><div class="">If the batteries are pretty low SOC, this won\u2019t happen.</div><div class="">If the ratio of PV to battery is too low, again hard to make it happen.</div><div class="">But if the ratio of PV to battery is pretty high as in most grid systems its more common.</div><div class="">I can\u2019t see how it would happen if the system was selling, don\u2019t know what mechanism would create the spike.</div><div class=""><br class=""></div><div class="">Depending on when in the day and how the system is set up, it next to impossible to have this spike in sell mode.

Hi Dan and Dave,<br class=""><br class="">
The system did not crash. <br class=""><br class="">
I think it must be a combination of the Midnite and Radian. The Radian
should sell to keep the voltage down and the Midnite should regulate. It
seems a bit mysterious to me. <br class=""><br class="">
Thanks,<br class=""><br class="">
