What to do if my Jntech JNP75KH Inverter shows State 09?
If the Jntech Inverter displays State 09, it means the water level of the source is lower than the low-level water level sensor, possibly even lower than the inlet of the pump. First, check the water level. If the water level is adequate, check for air inside the pump. Second, verify the position of the water level sensor.
How to fix R-Stat Test fail on Jntech JNP75KH Inverter?
The R-Stat Test failure on a Jntech Inverter can occur due to several reasons: a poor connection between the motor and inverter (short-circuit, open circuit, etc.), motor failure, or inverter failure. To address this, first, check the connection between the motor and inverter. Second, check the motor's condition. If both are fine, contacting the supplier is suggested.
Why does my Jntech Inverter display State 01?
State 01 on your Jntech Inverter indicates that the output energy from the array is changing. Please check the input voltage from the array and ensure it is within the inverter's input voltage range. Note that this is normal during cloudy days, mornings, or evenings and does not indicate a malfunction.
