Xantrex Technology Inverter Communications Adapter - Manual (Page 60)

On the other hand, if the SW Plus inverter’s display is parked
on a static menu item, then when you startup, the software
window may show a blank display for a few seconds.
This condition is nothing to worry about and should correct
itself in about 1 minute.
When the ICAP software shuts down, it will try to park the
inverter’s display at a more friendly menu location so that the
next time it starts up it doesn’t have these problem.
