[RE-wrenches] Rectifier

[Mac Lewis]

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!
