capacity.
Indicates that on L1 for single
inverters or L1 & L2 for paralleled
inverters that the output has a
short.

Do a complete system restart.
Once the system has restarted and is
online, ensure that loads are kept
under 110% of operating capacity.
Ensure all wiring is going to the
correct breaker and phases have not
crossed. If running multiple inverters,
test the continuity between the units
using a multimeter.
To run this test:
Do a complete system
shutdown as instructed
above.
Set the multimeter to Ohm
mode.
Take the Positive + (RED)
probe and place it in L1 on
the first inverter
Take the Negative - (BLACK)
probe and place it on L1 on
the second inverter.
The meter should read 0
If it reads OL then the two
lines are crossed or on the
same bus causing the short.
Ensure that the appropriately sized
wiring is being used (most use 10awg
wiring).
**
If problem persists, contact your retailer.
Ensure the inverter has sufficient
airflow and the vents/fans are not
clogged or blocked by debris.
Ensure that the fans spin freely.
Ensure the ambient temperature is
lower than 212° Fahrenheit.

If problem persists, contact your retailer.
