longer receiving any communication data via the Magnum Network.

5.3.4.2 Stacking Fault Messages
A fault condition may occur when multiple inverters are stacked in parallel
— using the router — that is not possible on a single inverter installation. Refer
to the following fault messages to help troubleshoot the inverters.
StackClock Fault
- 1. There is a stacker cable problem; or, 2. One
inverter is losing synchronization with the other inverter.
Remedy:
Ensure you are using the CAT 5 cables supplied with
the router for parallel stacking. Check to make sure you hear an
audible “click” when plugging in the CAT 5 cables.
Info:
This fault has been known to occur when a Magnum Energy
accessory is plugged into the Stack Port, but the installation is
not using multiple inverters in a stacked con
fi
guration. If this
occurs, perform an inverter reset (see Section 6.2).
Stack Mode Fault -
This unit has detected a problem with the “other”
stacked inverter, check that unit for a fault condition.
Remedy:
This fault will automatically clear when the fault with
the other inverter is corrected.
