Error codes will show on the Enerdrive Combi display when a warning is triggered or a fault occurs. Depending on the warning or fault encountered, the Combi may shutdown to protect itself until the fault has cleared.
See table below for more information on the Enerdrive Combi fault codes and how they might be cleared
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 turn 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 o 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 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 |
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 |
- "Cbr" = Circuit Breaker
- "GFCI" = Ground Fault Circuit Interrupter
