<div dir="auto">The inverters have a pretty tight frequency range, I have adjusted gennys to run out of that tight range, they just keep waiting for the frequency to come back. I can take a little tinkering on some models but even 57 hz is enough if your Hawaii with the HECo rule or California. You can go over too but if there is a lug it may still connect the inverter.<div dir="auto">Jerry</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Thu, Feb 25, 2021, 5:40 AM Nik Ponzio, Building Energy <<a href="mailto:nponzio@buildingenergyus.com">nponzio@buildingenergyus.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">We are installing 25kW of PV on a service with an existing backup generator (Eaton 30KW) and auto transfer switch. Because of the remote location of the generator and transfer switch, we can not easily connect on the grid-side of the transfer switch as we usually do (without cutting a very long trench.) So we're looking for a way to lock out the solar during generator use.
