4.0 Troubleshooting
Use Table 4-1 to troubleshoot your inverter. For CSW1012 or CSW2012
inverters, also use Table 4-2 to view the unit’s digital display to determine
what condition triggered the error/warning code and what corrective action
is needed.
Table 4-1, Troubleshooting Guide
Code
Condition
Corrective Action
E01
Unit has sensed the input
voltage is low (<10.5 VDC) and
will shut down in 30 seconds.
Immediately recharge the
battery (to at least 11.8 VDC),
and then restart unit.
E02
Unit has sensed the input
voltage is high and has shut
down.
Check the battery voltage, or if
an external charger is connected
to the battery bank.
E03
Unit output has sensed an
overload or short circuit and
was shut down.
Check the load connected to
the output. Reduce the load
and restart the unit.
E04
Unit has sensed the internal
temperature was high and has
shut down.
Turn the unit off and wait 15
minutes before restarting.
Check if the air
fl
ow is being
blocked.
E05
Unit has sensed the input
voltage is low and has initiated
a warning alarm (@11.2 VDC).
Recharge the battery (to at
least 11.8 VDC) as the unit will
shut down shortly.
E06
Unit has sensed that the
connected load is close to the
overload shutdown limit.
Reduce the connected load.
E07
Unit has sensed the internal
temperature is high and is close
to the thermal shutdown limit.
Reduce the load and check if
any of the unit’s ventilation is
blocked.
Problem
Symptom
Solution
No AC output. Status
indicator is off.
The unit is off.
Turn on the unit. See Operation
instructions.
No power to
inverter.
Check if fuse or disconnect
switch (if installed) is either
blown or turned off.
No AC output. Status
indicator is green.
GFCI was
tripped.
Check the connected load and
reset the GFCI.
No AC output. Fault
indicator is on.
Unit has
detected a fault
and has shut
down.
Determine and resolve the
fault condition (e.g., high or
low voltage, load too large, or
over-temperature).
For CSW1012
and CSW2012:
Check error code on the display
and use Table 4-2 to correct.
