Troubleshooting
Understanding Error Codes
If the products connected to PowerSource 1800 do not operate and the alarm is sounding, check PowerSource 1800 LED screen for an error code.
Troubleshooting Reference
Error
Possible Cause
Solution
E01
Low voltage shutdown because battery is discharged.
Recharge battery by plugging the AC power cord into a wall outlet.
E03
Overload shutdown while supplying backup power. The AC product(s)
connected are consuming more than PowerSource 1800’s power rating.
The AC products connected have a surge power that exceeds
PowerSource 1800 surge capability.
One or more of the connected products are damaged.
Use products with a total power consumption within PowerSource 1800’s continuous power rating of
1440 W.
Use products with a total starting surge power within PowerSource 1800’s capability of 2880 W.
Have the damaged product serviced by a qualified technician.
E04
Over-temperature shutdown has occurred. PowerSource 1800 has
overheated due to poor ventilation, excessive ambient temperature, or
power demand beyond the unit’s output power capability.
Disconnect products from the AC outlets. Allow the unit to cool for 20 minutes. Clear blocked fan or
remove objects covering unit. Move the unit to a cooler place. Reduce load to less than 1800 W if
continuous operation is required.
E05
Under-voltage warning. The battery is nearly discharged.
Reduce the load to extend run time during backup mode. Assuming the AC power cord was unplugged
and the unit turned to backup mode, when utility power is present or becomes available, recharge the
battery by plugging the AC power cord into a wall outlet.
E06
Over-temperature warning. PowerSource 1800 is overheating due to poor
ventilation, excessive ambient temperature, or high power demand.
Reduce the load to avoid over-temperature shutdown, clear blocked fan or remove objects covering unit,
or move the unit to a cooler place.
Problem
Problem/Symptom
Solution
PowerSource 1800 will
not turn on.
Battery is discharged and utility power is
not available at the wall outlet.
Ensure power is available at the wall outlet.
No power available at the
120 VAC outlets.
AC outlet has been overloaded or the
supplementary protector has tripped.
Reduce the number of products plugged into the AC outlets. Check the supplementary protector at the back of the
unit. If necessary, reset the breaker by pushing it fully inward.
AC utility is not available
and products connected to
unit lose power.
PowerSource 1800 has detected an
overload condition.
PowerSource 1800 has detected an over-
temperature condition.
PowerSource 1800 has exhausted its
available battery power.
PowerSource 1800 may require service.
Make sure the products plugged into
the
AC outlets are not exceeding the output power rating of the unit when
supplying backup power. Try removing or substituting some of the products.
Disconnect products from the AC outlets. Make sure the products plugged into the AC outlets are not overloading the
continuous output power rating of the unit when supplying backup power. Allow the unit to cool, increasing
ventilation if necessary. If the unit is left on, it restarts automatically when the unit cools down.
PowerSource 1800 shuts down when all available battery power has been used. Allow the unit to recharge for
15 hours before continuing to use the unit.
Contact Xantrex Technical Support for further troubleshooting (see “Contact Information” on page 1).
Products connected to unit
malfunction or overheat.
Products connected to PowerSource 1800
do not accept modified sine wave form.
Your application is not compatible with PowerSource 1800 modified sine wave output. See “Precautions for Using
Rechargeable Appliances” on page 2.
Inadequate run time.
PowerSource 1800 battery is not fully
charged.
Battery is near the end of its useful life.
PowerSource 1800 has turned off.
Charge the battery by leaving PowerSource 1800 plugged into a wall outlet at least 15 hours.
As the battery ages, the available run time decreases. The internal battery also ages prematurely if PowerSource 1800
is installed in a hot environment or not kept in a charged condition. See “Battery Replacement” on page 5.
Press for at least half a second to turn unit on.
