<pre wrap="">I am looking for an external output bypass assembly for a Xantrex 3 x
XW4024 system. My customer wants to be able to completely bypass the
inverter output and operate loads straight from the grid - similar to
what can be done in an Outback FlexWare system with their I/O bypass
assemblies.
This customer just wants the option of running loads direct from
utility. It has nothing to do with the inverter input side.
Any off-the-shelf solutions out there?
