Use Tables 4-1 and 4-2 to troubleshoot any issues—Table 4-2 includes the
error/warning codes that may appear on the inverter’s digital display.
Table 4 - 1 , Troubleshoot ing Guide
Code Condition Corr ect ive Action
E01 Unit has sensed the input
voltage is low (<21.0 V)
and has shut down.
Immediately recharge the battery
(to at least 23.6 V), and then
restart the unit.
E02 Unit has sensed the input
voltage is high (≥31.0 V)
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 has 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
for blocked air fl ow.
E05 Unit has sensed the input
voltage is low and has
initiated a warning alarm
(@ 22.4 V).
The alarm will continue until the
battery has been recharged to
≥23.6 V.
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 Sym pt om Solut ion
No AC output.
Status indicator
and digital
display are off.
The unit is off. Turn on the inverter
(see Operation instructions).
No power to inverter. Check if DC fuse or disconnect
switch (if installed) is either
blown or turned off.
No AC output.
Status indicator
is amber.
Check error code on
display.
Verify the error condition and
make necessary correction.
GFCI was tripped. Check the connected load and
reset the GFCI.
AC output is
turning off and
on every few
seconds.
The Load Sense
function is enabled,
and the inverter’s
connected load is less
than the threshold
setting (<10W).
Disable the Load Sense
function by changing the
inverter’s setting, or increase
the AC load connected to the
inverter to >10W.
