<div dir="ltr">Hi Wrenches,<div><br></div><div>From a power perspective, I'm comfortable with a 5000W inverter, covering some peak intermittent loads. As far as kWh/day, its going to be in the 10-15 kWh range I believe. if the rectifier and/or battery charger would do ~700-1000W 24/7, it should be plenty from a power perspective. Kirpal, I think your idea is sound, and I may do it but I have to see how the typical voltage profile looks. Grid support mode might be very effective, but it may be better to rectify. Its a sprawling farm property with quite a few loads tapped into the feeder circuit, so the sag might be significant. I can see them using that feeder for livestock tank heaters and irrigation pumps etc.</div><div><br></div><div>Thanks for all of the info!</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Fri, Apr 17, 2020 at 9:30 AM Jay <<a href="mailto:jay.peltz@gmail.com">jay.peltz@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="auto"><div dir="ltr">Hi Mac</div><div dir="ltr"><br></div><div dir="ltr">All depends on how much power do you want out there?</div><div dir="ltr"><br></div><div dir="ltr">Jay</div><div dir="ltr"><br></div><div dir="ltr">Peltz power</div><div dir="ltr"><br></div><div dir="ltr"><br></div><div dir="ltr"><br></div><div dir="ltr"><br><blockquote type="cite">On Apr 17, 2020, at 7:08 AM, Glenn Burt <<a href="mailto:Glenn.burt@glbcc.com" target="_blank">Glenn.burt@glbcc.com</a>> wrote:<br><br></blockquote></div><blockquote type="cite"><div dir="ltr">\ufeff

I'm running
through a couple of scenarios that may work. Its a ADU (accessory dwelling unit) that is about 1100' from power. The farmer had taken it upon himself to bury some 4/0 a few years ago to run power out there. Voltage drop is the big issue and its not going to pass the AHJ inspection. We could just ditch the grid and go off-grid, but it seems like a shame to not tap into the grid resource. Instead of dealing with the voltage drop, I was thinking it may make sense to rectify that low AC voltage input and parallel a smallish battery bank (size is yet to be determined), then use an off-grid inverter to serve the loads at good voltage.</div><div><br></div><div>I am looking for feedback on this concept. What do you think?</div><div><br></div><div>Also, are there any recommendations for good quality rectifiers with wide input voltage window? </div><div><br></div><div>Thanks in advance for your help</div><div><div><br></div>--
