Apparently all the feed in inverters are required to not supply
voltage when there isn't voltage present on the supply line. This in
theory prevents your inverter supplying a nice hit of current to the
poor linesman - additionally trying to supply current that is out of
phase with the (much bigger) grid supply is generally a recipe for
your inverter sinking a large amount of current from the grid (usually
in a way that releases the magic smoke)
