IMPORTANT OPERATIONAL NOTE:
When two (or more) Power+ units are being operated in parallel mode, and the system is manually moved
to bypass mode, the return of the system to Inverter mode must be performed on the same unit that was
used to transfer the system to bypass mode. If you attempt to return the system to Inverter mode on a unit
other than the one that was used to put the system in bypass mode, the command will not be accepted.
