What does it mean when my Huawei SUN2000-4.95KTL-JPL1 displays Abnormal Residual Current?
- C
  Chad MillerSep 7, 2025
  An 'Abnormal Residual Current' error on your Huawei Inverter indicates that the insulation impedance of the input side to PE decreases when the SUN2000 is operating. Here's how to address it: 1. If the alarm occurs occasionally, the external circuit may be temporarily abnormal, and the SUN2000 will recover after the fault is rectified. 2. If the alarm occurs frequently or persists, check whether the impedance between the PV string and the ground is too low.

What to do if my Huawei SUN2000-4.95KTL-JPL1 Inverter shows Output DC Component Overhigh?
- R
  Reginald CastroSep 6, 2025
  An 'Output DC Component Overhigh' error on your Huawei Inverter means the DC component of the SUN2000 output current exceeds the specified upper threshold. Here's what to do: 1. The SUN2000 detects its external working conditions in real time and automatically recovers after the fault is rectified.

What to do for Huawei SUN2000-4.95KTL-JPL1 Abnormal Grounding error?
- G
  gordonjamieSep 5, 2025
  An 'Abnormal Grounding' error on your Huawei Inverter can be caused by: 1. The neutral wire or PE cable of the SUN2000 not being connected. 2. The output mode set for the SUN2000 being inconsistent with the cable connection mode. To resolve this, power off the SUN2000 (turn off the AC output switch and DC input switch, and wait for a period of time), and then: 1. Check that the PE cable of the SUN2000 is connected properly. 2. If the SUN2000 is connected to a TN power grid, check whether the neutral wire is properly connected and whether the voltage of the neutral wire to ground is normal. 3. After powering on the SUN2000, check whether the output mode set for the SUN2000 is consistent with the output cable connection mode.

What does it mean if my Huawei SUN2000-4.95KTL-JPL1 shows Output Overcurrent?
- L
  Lisa LarsonSep 5, 2025
  An 'Output Overcurrent' error on your Huawei Inverter means the power grid voltage drops dramatically or the power grid is short-circuited. Here's what to do: 1. The SUN2000 detects its external working conditions in real time and automatically recovers after the fault is rectified. 2. If the alarm occurs frequently and affects the energy yield of the power plant, check whether the output is short-circuited.

What does Unstable Grid Frequency mean on my Huawei SUN2000-4.95KTL-JPL1 Inverter?
- T
  Thomas SchmittSep 4, 2025
  An Unstable Grid Frequency error on your Huawei Inverter indicates a power grid exception where the actual grid frequency change rate does not comply with the local power grid standard. Here's what to do: 1. If the alarm occurs occasionally, the power grid may be temporarily abnormal, and the SUN2000 will automatically recover. 2. If the alarm occurs frequently, check whether the power grid frequency is within the allowed range. If not, contact the local power operator.

What does it mean when my Huawei SUN2000-4.95KTL-JPL1 displays Grid Underfrequency?
- C
  Casey PerkinsSep 3, 2025
  A Grid Underfrequency error on your Huawei Inverter means there's a power grid exception: the actual power grid frequency is lower than the standard requirement for the local power grid. To resolve this: 1. If the alarm occurs occasionally, the power grid may be temporarily abnormal, and the SUN2000 automatically recovers. 2. If the alarm occurs frequently, check whether the power grid frequency is within the allowed range. If not, contact the local power operator. If yes, modify the grid underfrequency protection threshold through the mobile app, SmartLogger, or NMS with the consent of the local power operator.

What causes a Huawei Inverter to show Grid Overfrequency?
- J
  James PowellSep 2, 2025
  A Grid Overfrequency error on your Huawei Inverter indicates a power grid exception where the actual power grid frequency is higher than the standard requirement for the local power grid. Follow these steps: 1. If the alarm occurs occasionally, the power grid may be temporarily abnormal, and the SUN2000 will automatically recover. 2. If the alarm occurs frequently, check whether the power grid frequency is within the allowed range. If not, contact the local power operator. If it is, modify the grid overfrequency protection threshold through the mobile app, SmartLogger, or NMS with the consent of the local power operator.

What should I do if my Huawei SUN2000-4.95KTL-JPL1 Inverter has an AFCI Check Failure?
- K
  Kelsey SantiagoSep 1, 2025
  If your Huawei Inverter shows an 'AFCI Check Failure', turn off the AC output switch and DC input switch, and then turn them on again after 5 minutes.

What does it mean when my Huawei Inverter displays PV String Loss?
- T
  tonya78Aug 31, 2025
  The PV String Loss alarm on your Huawei Inverter indicates an abnormal PV string status due to: a single PV string loss, both 2-in-1 PV strings loss, or one of the 2-in-1 PV strings loss. To resolve this, check the following: 1. Check whether the SUN2000 terminals are properly connected. 2. Check whether the PV string terminals are properly connected. 3. If a 2-in-1 terminal is used, check whether it is normal.

Why does my Huawei SUN2000-4.95KTL-JPL1 Inverter show Overtemperature?
- W
  walkercameronAug 31, 2025
  An 'Overtemperature' error on your Huawei Inverter can occur due to: 1. The SUN2000 being installed in a place with poor ventilation. 2. The ambient temperature exceeding the upper threshold. 3. The SUN2000 not working properly. To resolve this: 1. Check the ventilation and ambient temperature of the SUN2000 installation position. 2. If ventilation is poor or the ambient temperature exceeds the upper threshold, improve ventilation and heat dissipation.
