<p><span style="font-size: 11pt;">A Radian 4048 disconnected from the grid with a high grid voltage error showing on the Mate 3. The Mate 3 was displaying a voltage of 279 - 280 V. The Mate 3 was replaced with another Mate 3, and the high voltage reading remained. </span></p>
<div class="pre" style="margin: 0; padding: 0; font-family: monospace"><span style="font-size: 11pt;">When the voltage was checked with two separate multi meters, the readings came out to 249 - 250 V. I believe that the 249 - 250 volt reading is correct. <br /></span></div>

<div class="pre" style="margin: 0; padding: 0; font-family: monospace"><span style="font-size: 11pt;">The incorrect, high voltage reading seems to be coming for the inverter, not the Mate 3, since two Mates were used. </span></div>
