I remember William the X SW and the Trace SW before that:) I am not sure if I qualify to say those were good times as I have always been offgrid by several miles. The more the better!
Schneider and Outback have taken steps with their recent inverter/chargers to keep that feed to the grid from happening. Several inverter/chargers will do this. The CSW has a mode that keeps the grid V higher (current flows) so the CSW can't back feed and get the user in trouble. They all call it different things like xero export, self consumption, and enhanced AC support. Most use the mppt to trigger. A sub panel is fed with the loads that the user wants backed up and powered when the sun is out. When the grid is gone the sub panel is on battery power. When there is not enough sun the grid powers the balance to the sub panel. If anyone needs any of these old devices please contact me off line as there is this storage shed of SW's and MX-60s :) Dave Angelini Offgrid Solar "we go where powerlines don't" http://members.sti.net/offgridsolar/ e-mail [email protected] text 209 813 0060 > Friends: > > > > Some of you may remember when the original Xantrex SW inverters were > approved for grid-tie and then that approval was rescinded.
