<div dir="ltr"><div><div>Thanks all for the detailed explanations as to why backfeeding a generator is a potential problem. Tump, I think in general, that is often the case, but I have seen regular grid tie inverters pickup some average generators. The bottom line is do we want to take the risk, even if small, of owning a blown generator. We have in most cases chosen to avoid this possibility by either tying in above the automatic transfer switch, or putting a relay in that disconnects the inverter when the generator connects to the house. If someone wants to take on that risk, that is their own decision. I just object when the installer is not upfront about the potential problem.<br></div><br></div>Howie<br></div><div class="gmail_extra"><br><div class="gmail_quote">On Wed, Oct 21, 2015 at 7:24 AM, Chris Mason <span dir="ltr"><<a href="mailto:cometenergysystems@gmail.com" target="_blank">cometenergysystems@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><p dir="ltr">That trends to be the saving grace for most installations, however in the islands, we modify the inverter parameters to accept poor quality power.
