Troubleshooting
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 has shut down.
Immediately recharge the
battery (to at least 11.8 VDC),
and then restart unit.
E02
Unit has sensed the input
voltage is high (
≥
15.5 VDC)
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 unit off and wait 15
minutes before restarting.
Check for blocked air
fl
ow.
E05
Unit has sensed the input
voltage is low and has initiated
a warning alarm (@11.2 VDC).
The alarm will continue
until the battery has been
recharged to
≥
11.8 VDC .
E06
Unit has sensed that the
connected load is close to the
overload shutdown limit.
Reduce the connected load.
E07
Unit sensed the internal
temperature is high and close
to the thermal shutdown limit.
Reduce 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. Refer to Table 4-2.
