Understanding the Error Codes
Code
Condition
Corrective Action
E01
(Battery
Mode)
No AC Output. Inverter shutdown due to low
battery voltage.
Recharge the battery immediately and restart unit.
Note: E01 will shows for about 30 sec. After 30 sec, Display will turns Off and unit will shutdown completely.
E01
(By-
Pass
Mode)
- No battery is connected to the unit.
- Check the battery connection.
- Battery voltage remains < 9.5V. A large portion of
the charger current provided is used to maintain
the DC load connected to the battery. E01 will turn
OFF when the battery voltage is charged to >
9.5V
- Remove or turn off DC load connected to the battery
to minimize the charging time to charge the battery to
> 9.5V. If this condition is ignored, the charger will
terminate the charging process (See note below).
Note: The charger current with battery voltage < 9.5V is limited to ~25A and there is a 15 minute timer to
allow the charger to charge the battery to > 9.5V. If battery voltage remains < 9.5V after 15 minutes of charge,
the charger will shutdown and show E11 (Bad battery).
E02
When unit is in Battery/Inverter mode, unit senses
the battery voltage is too high and inverter has
shutdown.
Check battery voltage or determine if any external
charger is connected to the battery bank that leads to
high battery voltage.
E03
When unit is in Battery/Inverter mode, AC output is
overloaded or short-circuited and inverter has
shutdown.
Check load connected to the output. Reduce load and
restart the unit.
Note: E03 will shows for about 30 seconds. After 30 seconds, Display will turns Off and unit will shutdown
completely.
E04
When unit is in Battery/Inverter mode, Internal
temperature is too high and inverter has shutdown.
Turn unit off and wait for 15 minutes before restarting.
Check if any object has blocked the airflow of the unit.
E05
When unit is in Battery/Inverter mode Input battery
voltage is low and warning occurs.
Recharge battery as unit will shutdown shortly.
E06
When unit is in Battery/Inverter mode AC output
load connected has been sensed high and is close
to shutdown limit.
Reduce AC load.
Note: E06 occurs when AC Output power is close to
1850W for 2000W units and 2800W for 3000W unit.
E07
When unit is in Batter/Inverter mode Internal
temperature is high and is close to over-
temperature shutdown limit.
Reduce load and check if any ventilation of the unit is
blocked.
E10
When unit is in By-Pass mode, Battery Charging
voltage too high.
Check battery setting. Check and any other DC power
sources connected to the battery has high voltage.
E11
Bad Battery classification: E01 (By-Pass Mode)
condition has not been solved. AC Charger has
shutdown.
- Check corrective action in E01 (By-pass Mode) and
restart the charging process by removing and
reconnecting the AC Input Source.
Other conditions leading to Bad Battery
Classification: Battery Voltage remains below
2/5/9.5V after 2/5/15 minutes of charge.
- Check if there is any heavy DC load connected to the
battery as stated in E01 (By-pass mode). Restart the
charging process.
- Change to a new battery.
E12
When unit is in By-Pass mode, Internal transfer
switch temperature is high and shutdown occurs.
Reduce load and check if any ventilation of the unit is
blocked.
E13
AC Output GFCI Tripped.
Reset the GFCI.
Note: This error function is not effective when Load Sense “LdS’ function is in use.
E14
Display panel has communication error.
Check RJ12 cable connected between the main and
Display panel.
E15
AC Back Feed to Unit AC Output.
Check AC Input and AC Output wiring.
E16
Internal Fault. Unit damage.
Consult Customer Service for assistance.
E17
AC Input Current withdrawn from the unit is close to
the set AC Circuit Breaker (Cbr) rating.
Reduce AC load. Check the AC Circuit Breaker (Cbr)
rating match with the external AC Input Source Branch
Breaker rating.
E18
AC Input Current drawn by unit is beyond the
current rating of the transfer switch. (30A for 120V
model, 16A for 230V model). AC Output Switch is
switched off.
Reduce AC Load connected to unit. Press and hold
‘Escape’ button for 5 seconds to reset AC Output
Switch to provide AC Output from AC Input Source.
E19
Battery temperature sensed by BTS is > 60°C.
Battery charging cycle terminates.
Cool down the battery. Battery charging cycle will
automatically resume when the temperature drops to
below 50 °C.
E20
Battery temperature sensed by BTS is > 55 °C and
is close to battery temperature thermal shutdown
Check battery and environmental temperature or add
ventilation to the battery compartment.
E21
Battery temperature sensed by BTS is < 0 °C.
Battery charging cycle terminates.
Check battery and environmental temperature. The
charging cycle will resume when temperature
increases to > 5 °C.
