Parallel Operation
CAUTION: If there is a communication issue, the ME-RTR's top line will show the
inverter's status (e.g., Off, Inverting, Searching) rather than identifying that port's
connected inverter as a master or slave unit. In that case, the router mistakes the unit
as a standalone inverter, will not sync properly, and may result in damage to that unit—
possibly causing damage to the other inverters in the system as well.
