What does abnormal active power scheduling instruction mean on a Huawei SUN2000-15KTL-M5 Inverter?
- C
  chad36Sep 6, 2025
  If your Huawei Inverter displays an abnormal active power scheduling instruction, it means the DI input is abnormal or inconsistent with the configuration. Check whether the cables are correctly connected to the DI ports. On the DI active scheduling screen under the dry contact scheduling settings, view the DI signal configuration mapping table. Contact the power grid company to check whether the configurations in the mapping table are complete and meet the requirements.

How to fix low insulation resistance on Huawei SUN2000-15KTL-M5 Inverter?
- V
  Victor GuerreroAug 25, 2025
  A low insulation resistance error on your Huawei Inverter indicates a short circuit between the PV array and PE, or that the PV string has been in a moist environment for a long time, leading to poor insulation to ground. To resolve this: * Check the impedance between the PV string and the PE cable for shorts and fix them. * Ensure the inverter's PE cable is correctly connected. * If the low impedance is confirmed in cloudy or rainy conditions, adjust the insulation resistance protection threshold via the app, SmartLogger, or NMS.

How to resolve high string input voltage on a Huawei SUN2000-15KTL-M5?
- J
  Justin ParkerAug 26, 2025
  A high string input voltage error on your Huawei Inverter means the PV array isn't properly configured, with too many PV modules connected in series, causing the PV string open-circuit voltage to exceed the inverter's maximum operating voltage. Reduce the number of PV modules connected in series until the PV string open-circuit voltage is at or below the inverter's maximum. The alarm should then disappear.

What causes grid undervoltage on Huawei Inverter?
- J
  Jacob SmithAug 26, 2025
  A grid undervoltage error on your Huawei Inverter means the power grid voltage is too low, or the low voltage duration exceeds the LVRT specified value. Here's how to handle it: 1. If it's occasional, it might be a temporary grid issue; the inverter should recover automatically. 2. If it persists, check if the grid voltage is within range and contact the local power operator if it's not. If it is, you can modify the grid undervoltage protection threshold via the app, SmartLogger, or NMS, with the power operator's consent. 3. If it continues, inspect the AC circuit breaker and AC output power cable.

What does abnormal reactive power scheduling instruction mean on a Huawei Inverter?
- D
  Danny MillerSep 7, 2025
  If your Huawei Inverter displays an abnormal reactive power scheduling instruction, it means the DI input is abnormal or inconsistent with the configuration. Check whether the cables are connected correctly to the DI ports. On the DI reactive power scheduling screen under the dry contact scheduling settings, view the DI signal configuration mapping table. Contact the power grid company to check whether the configurations in the mapping table are complete and meet the requirements.

How to resolve String Reverse Connection on Huawei SUN2000-15KTL-M5?
- B
  Brandy AcostaSep 12, 2025
  If your Huawei Inverter is showing a 'String Reverse Connection' error, it means the polarity of the PV string is reversed. To fix this, wait until night when solar irradiance is low and the PV string current drops below 0.5 A. Then, turn off the DC switch and correct the PV string connection.

What does abnormal residual current mean on a Huawei Inverter?
- B
  Brandon RomeroSep 2, 2025
  An abnormal residual current on your Huawei Inverter indicates that the insulation impedance on the input side to PE has decreased during operation. If the alarm occurs accidentally, the external power cable may be temporarily abnormal, and the inverter will recover automatically after the fault is rectified. If the alarm persists or lasts a long time, check whether the impedance between the PV string and ground is too low.

Why am I getting an output DC component overhigh error on my Huawei SUN2000-15KTL-M5 Inverter?
- R
  raymondkennedySep 3, 2025
  An output DC component overhigh error on your Huawei Inverter means the DC component of the inverter's output current is too high. The inverter will monitor external conditions and try to recover automatically. If the alarm persists and affects energy yield, contact your dealer or Huawei technical support.

Why is my Huawei SUN2000-15KTL-M5 Inverter showing an output overcurrent error?
- J
  Jessica MontgomeryAug 30, 2025
  An output overcurrent error on your Huawei Inverter indicates that the grid voltage has dropped dramatically or the grid is short-circuited, causing the inverter's output current to exceed the limit. The inverter will monitor conditions and try to recover automatically. If the alarm persists and affects energy yield, check for a short circuit in the output. If you can't fix it, contact your dealer or Huawei technical support.

What to do if Huawei SUN2000-15KTL-M5 shows AFCI self-check failure?
- J
  Jackson ManningAug 29, 2025
  If your Huawei Inverter shows an AFCI self-check failure, turn off both the AC output switch and the DC input switch. Wait for 5 minutes, then turn them back on. If the alarm continues, contact Huawei technical support.
