| Error Code | Meaning (from manual) | What you do | | :--- | :--- | :--- | | | Overheating | Clean the cooling fan. Move inverter out of the sun. | | E.LU | Low Voltage | Battery is dying or input wire is too long/thin. | | E.SC | Short Circuit | Unplug all loads. Plug them back one by one to find the faulty device. | | E.OC | Over Current | Motor is jammed (VFD) or too many appliances turned on at once (Solar). |
JTE-1K, JTE-2K, JTE-3K, JTE-5K (Hybrid/Solar/Off-Grid) Document Version: 1.0 Jte Inverter Manual
A system error or protection mechanism has been triggered. LCD Display Parameters | Error Code | Meaning (from manual) |
Programming your JTE inverter to work with your specific motor and application is done by setting function codes. The process typically involves entering the programming menu (by pressing the PRGM key), navigating to a parameter number (like P0.00 ), and setting its value. | Clean air vents
| | Common Error Codes | Typical Causes | Basic Troubleshooting Steps | | :--- | :--- | :--- | :--- | | Overcurrent (OC) | ERR10, OC | Short circuits, jammed motors, rapid acceleration, faulty IGBTs. | Check motor and wiring for short circuits; confirm mechanical parts move freely; verify acceleration time is not too short. | | Overvoltage (OV) | OV, OU | Grid voltage spikes, rapid deceleration of a heavy load, faulty braking resistors. | Confirm grid voltage is within specs; inspect brake resistors for damage; increase deceleration time. | | Overload (OL) | OL, OH | Motor running beyond its rated power for extended periods (e.g., pump with excessive flow). | Check if the mechanical load is too high; verify the motor's rated current matches the inverter's settings. | | No Output | N/A | No power supply, loose wiring, incorrect parameter settings, or faulty logic board. | Confirm the inverter is receiving power; check all control wiring; ensure start signals are active and parameters are correct. | | Overheating | OH, F4 | Inadequate ventilation, fan failure, high ambient temperature. | Clean air vents; check if the cooling fan is working; ensure the inverter is not in direct sunlight. |
Units can go into "dormant" mode during weak light (sunset) and automatically "wake up" at sunrise or when water levels shift.
