Hi Wrenches, >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.
Thanks for all of the info!
