StackClock Fault
Settings/Info...
Figure 5-45, StackClock Fault
• StackClock Fault (StkClock) – 1. There is a stacker cable problem; or, 2. One inverter is
losing synchronization with the other inverter.
Remedy: Ensure you are using the RJ45 cables supplied with the router for parallel
stacking. Check to make sure you hear an audible “click” when plugging in the RJ45
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
confi guration. If this occurs, perform an inverter reset (see Section 6.2).
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.

INV (green) LEDs are off.
Figure 5-46, Stack Mode Fault
• Stack Mode Fault (Stk Mode) – This unit has detected a problem with another stacked
inverter, check the other units for a fault condition.
Remedy: This fault will automatically clear when the fault with the other inverter is
corrected.

StackPhase Fault
Settings/Info...
StackPhase Fault appears on the LCD and the FAULT
(red) LED is on. The PWR (green), CHG (green), and
INV (green) LEDs are off.
Figure 5-47, StackPhase Fault
• StackPhase Fault (StkPhase) – 1. The AC input wiring is incorrect; or, 2. One phase was
lost from the AC input source; or, 3. One of the inverter’s internal transfer relays is bad; or, 4.
The inverter’s AC input circuit breaker may be open.
Remedy: If this fault doesn’t clear after checking these four recommendations, perform
an inverter reset (Section 6.2).
