What does Grid-tied/Off-grid Controller Abnormal mean on Huawei SUN2000-4.6KTL-L1 Inverter?
- N
  Nicole VargasSep 5, 2025
  If your Huawei Inverter displays a Grid-tied/Off-grid Controller Abnormal message, it indicates that the inverter fails to communicate with the Smart Backup Box. Send a shutdown command on the app. Turn off the AC output switch, DC input switch, and battery switch. Check whether the power cable and RS485 cable between the Smart Backup Box and the inverter are normal. After 5 minutes, turn on the battery switch, AC output side, AC output switch, and DC input switch.

Why is my Huawei SUN2000-4.6KTL-L1 Inverter showing High String Input Voltage?
- S
  Sherri HallAug 25, 2025
  If your Huawei Inverter displays a High String Input Voltage error, it's because the PV array is not properly configured. Specifically, too many PV modules are connected in series, causing the open-circuit voltage to exceed the SUN2000's maximum operating voltage. To resolve this, check the serial connection configuration of the PV string and ensure that the PV string open-circuit voltage does not exceed the SUN2000's maximum operating voltage. After correcting the PV array configuration, the alarm should disappear.

What to do if my Huawei SUN2000-4.6KTL-L1 Inverter showing Overtemperature?
- K
  Katherine ChambersAug 26, 2025
  If your Huawei Inverter is showing an Overtemperature warning, it indicates that the unit is installed in a location with poor ventilation, the ambient temperature is too high, or the SUN2000 is not working properly. You should check the ventilation and ambient temperature of the SUN2000 installation position. If the ventilation is poor or the ambient temperature exceeds the upper threshold, improve the ventilation and heat dissipation.

What to do if Huawei SUN2000-4.6KTL-L1 Inverter displays String Reversed?
- G
  Gregory RivasAug 27, 2025
  If your Huawei Inverter displays a String Reversed error, it means the PV string is reversely connected. Check whether the PV string is reversely connected to the SUN2000. If it is, wait until the PV string current decreases below 0.5 A, set the DC switch to OFF, and adjust the PV string polarity.

What does Battery Abnormal mean on my Huawei SUN2000-4.6KTL-L1 Inverter?
- M
  Marissa SmithSep 3, 2025
  If your Huawei Inverter displays a Battery Abnormal message: * If the battery fault indicator is steady on or blinking, contact the battery supplier. * Check that the battery enabling/power/ communications cable is correctly installed, and that the communications parameters are the same as the SUN2000 RS485 configurations. * Check that the auxiliary power switch on the battery is set to ON. * Send a shutdown command on the app. Turn off the AC output switch, DC input switch, and battery switch. Then turn on the battery switch, AC output switch, and DC input switch in sequence after 5 minutes.

What to do if Huawei Inverter showing Faulty Power Collector?
- J
  James TurnerSep 3, 2025
  If your Huawei Inverter is showing a Faulty Power Collector message: * Check that the configured power meter model is the same as the actual model. * Check that the communications parameters for the smart power sensors are the same as the SUN2000 RS485 configurations. * Check whether the smart power sensor is powered on and whether the RS485 communications cable is connected.

What to do if my Huawei Inverter shows Low Insulation Resistance?
- R
  Roger WhiteAug 29, 2025
  If your Huawei Inverter shows a Low Insulation Resistance error, it indicates a short circuit between the PV array and the ground, or that the ambient air of the PV array is damp, causing poor insulation. First, check the output impedance of the PV array to ground. If there is a short circuit or lack of insulation, rectify it. Second, check that the PE cable of the SUN2000 is correctly connected. Third, if the impedance is lower than the specified protection threshold in rainy and cloudy days, set Insulation resistance protection using the mobile app, SmartLogger, or NMS.
