What does Battery Reverse Connection mean on my Huawei Inverter?
- A
  Aaron BradleySep 13, 2025
  A 'Battery Reverse Connection' error on your Huawei Inverter means the positive and negative poles are reversed when the battery is connected to the SUN2000. To fix this: 1. Turn off the AC output switch, DC input switch, and battery switch, and turn on the battery auxiliary power switch. Wait for 5 minutes. 2. Check the cable connection by referring to the SUN2000L Battery and Smart Meter Quick Installation Guide. 3. After ensuring that the battery power cable is correctly connected, turn on the battery auxiliary power switch, battery switch, AC output switch, and DC input switch in sequence.

Why is my Huawei SUN2000-4.95KTL-JPL1 Inverter showing High String Input Voltage?
- P
  Peter AcostaAug 25, 2025
  The 'High String Input Voltage' error on your Huawei Inverter indicates that the PV array is not properly configured. Too many PV modules are connected in series, causing the open-circuit voltage to exceed the SUN2000's maximum operating voltage. To fix this, check the serial connection configuration of the PV string and ensure the open-circuit voltage is not greater than the maximum operating voltage of the SUN2000. After correcting the PV array configuration, the alarm should disappear.

How to fix a Huawei Inverter with String Reversed error?
- J
  Jason TurnerAug 26, 2025
  If your Huawei Inverter shows a 'String Reversed' error, it means the PV string is reversely connected. Check if 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 Active Islanding mean on my Huawei SUN2000-4.95KTL-JPL1?
- R
  Robert MorrisonSep 14, 2025
  The 'Active Islanding' error on your Huawei Inverter indicates that when the power grid experiences an AC power outage, the SUN2000 detects islanding proactively. Check that the grid connection voltage of the SUN2000 is normal.

What does Passive Islanding mean on my Huawei SUN2000-4.95KTL-JPL1?
- R
  Raymond WolfSep 14, 2025
  The 'Passive Islanding' error on your Huawei Inverter indicates that when the power grid experiences an AC power outage, the SUN2000 detects an island grid passively. Check whether the voltage at the grid connection point of the SUN2000 is normal.

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 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 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.

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.
