What does it mean when my Jntech JNP1K5L-V5 Inverter shows 'Temperature sensor fault'?
If your Jntech Inverter indicates a 'Temperature sensor fault', it means the sensor is either not properly connected or is damaged. If this issue occurs frequently, contact your supplier.
Why does my Jntech JNP1K5L-V5 show 'Array over-voltage'?
If the Jntech Inverter displays 'Array over-voltage,' it signifies that the DC input voltage exceeds the inverter's maximum input voltage. To resolve this, check the maximum output voltage of the array and ensure it remains below the inverter's maximum input voltage.
What causes 'Inverter AC output over current' on a Jntech JNP1K5L-V5?
If your Jntech Inverter reports 'Inverter AC output over current', it could be due to several reasons: the pump motor's power capacity exceeds the rated output, the pump motor is locked or damaged, or the pipe system design is unreasonable. Inspect the pump motor to ensure it is working correctly and check if the pipeline system matches the water pump specifications. If this issue occurs frequently, contact your supplier.
What should I do if my Jntech Inverter displays 'Grid power overvoltage'?
If your Jntech Inverter shows 'Grid power overvoltage', it means that the local grid power voltage is unstable and high, or there is a hardware failure. Check the input of the AC power, and if the voltage value is too high, disconnect the grid power. Contact your supplier for further assistance.
What to do if my Jntech JNP1K5L-V5 Inverter has a 'Short circuit fault (Nonrecoverable)'?
If your Jntech Inverter displays a 'Short circuit fault (Nonrecoverable)', it indicates a short circuit in the output wires. Check the output wires for any short circuits. If the issue persists, contact your supplier.
Why is my Jntech JNP1K5L-V5 showing 'Grid power undervoltage'?
If your Jntech Inverter shows 'Grid power undervoltage', it could be because the grid power switch isn't closed or the grid input is unstable and lower than the minimum operating voltage. First, check if the AC input switch is closed. Then, verify that the local grid voltage is normal.
How to fix State 109 Dry alarm on Jntech JNP1K5L-V5?
If your Jntech Inverter shows a State 109 Dry alarm, it indicates that the water level of the water source is lower than the lower level sensor, possibly even lower than the pump inlet. First, check the water level. If the water level is adequate, check for air inside the pump. Also, verify the position of the water level sensor.
What to do if my Jntech JNP1K5L-V5 shows Fault100 Driver over-current?
If your Jntech Inverter displays a Fault100 Driver over-current error, the possible cause may be a short circuit of the inverter output wires or hardware circuit damage. Check for any short circuits between the 3-phase output wires.
What should I do if my Jntech JNP1K5L-V5 Inverter displays an 'Overflow alarm'?
If your Jntech Inverter displays 'Overflow alarm' it means that the water level in the container is higher than the high-end level sensor. If this occurs repeatedly, inspect the site and adjust the water level sensor to a suitable height.
What to do when my Jntech JNP1K5L-V5 reports 'Output phase lose'?
If your Jntech Inverter displays 'Output phase lose', it indicates a phase loss in the inverter output. Check if the output wires are properly connected and fixed. If this issue persists, contact the supplier.
