Many of these clients are not willing to go the extra mile to interface the solar system with the back up gen. I am wondering if any of you out there have found simple fail safe solutions for preventing generator back feed when relays and switch gear are difficult or impossible to implement. </div><div><br></div><div> I have been thinking perhaps a large enough diode on the gen output could do it, but then what happens to the grid tied inverter when there is no where for the power to go?</div><div><br></div><div>I know this is vague, but I am searching the hive to see if there is a better way to make these customers happy and make the sale.</div><div><br></div><div>Thanks</div><div>Daniel</div><div><br><div><br clear="all"><div><div class="gmail_signature"><div dir="ltr">Daniel Tittmann <div>CTO</div><div>Greenwired</div><div><a href="http://www.greenwired.com" target="_blank">www.greenwired.com</a></div><div><a href="mailto:daniel@greenwired.com" target="_blank">daniel@greenwired.com</a></div><div>707-923-2001 (office)</div><div>707-206-5088 (Cell)</div></div></div></div>
