StackPhase Fault -
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).
5.3.4.3 Internal Fault Messages
The inverter continually monitors several internal components. If a condition
inside the inverter occurs that does not allow proper operation, the inverter
shuts down to protect itself. To clear these “internal” faults, the inverter will
require an inverter reset.
Remedy:
Perform an inverter reset (see Section 6-2). After
resetting the inverter, press the ON/OFF INVERTER button to turn
the inverter on and verify the fault has cleared. If the internal
fault remains, the inverter will require repair at an authorized
service facility.
Internal Bridge
- This fault message displays and the inverter shuts down
because the internal power-bridge protection circuit has been activated.
Internal Charger
- This fault message displays and the inverter shuts
down because the internal charger protection circuit has been activated.
