What to do if my Afore HNS2500TL-1 shows 'No Utility'?
- S
  Sandra StephensAug 19, 2025
  If your Afore Inverter displays a 'No Utility' error, it could be due to several reasons: a utility loss, a tripped AC side circuit breaker, a poor AC side connection, or an inverter fault. If the grid returns to normal, the inverter should restart automatically. Try replacing the AC circuit breaker or checking the AC connector for a secure connection. If the fault persists after several restarts, the inverter may need to be replaced.

What to do if Afore HNS2500TL-1 displays 'Over Temperature Fault'?
- J
  Joseph ChapmanAug 21, 2025
  If your Afore inverter shows an 'Over Temperature Fault', it could be due to the inverter enclosure being too hot or a temperature sensor fault. Turn off the inverter and allow it to cool down to a normal temperature, or install the inverter in a well-ventilated area. If the problem continues, replace the temperature sensor.

Why is my Afore HNS2500TL-1 Inverter showing a 'Bus High Fault' or 'Bus Fault'?
- P
  Paul MartinAug 25, 2025
  A 'Bus High Fault' or 'Bus Fault' on your Afore inverter can be caused by a high PV input voltage or a poor AC side connection. Ensure the PV input voltage is within the specified limits: 450Vdc for models up to 3.0kW, or 500Vdc for models up to 5.0kW. Also, check the AC connector and circuit breaker for a secure connection.

What causes a 'Ground Current Fault' in Afore Inverter and how to fix it?
- E
  Erica LopezAug 26, 2025
  A 'Ground Current Fault' in your Afore inverter may be caused by poor earthing leading to high leakage current, or the PV(+) or PV(-) being earthed. Check the AC output wiring and restart the inverter. Also, inspect the PV array wiring.

What should I do if my Afore HNS2500TL-1 shows 'PV Over Fault'?
- D
  Dr. Austin CarrollAug 28, 2025
  If your Afore Inverter displays a 'PV Over Fault', it indicates that the PV array's Voc (open-circuit voltage) is too high. Redesign the PV array configuration. Also, measure the PV array voltage to ensure it matches what the inverter displays.

What to do if my Afore Inverter shows PV1 Over Current?
- H
  Heather BlackAug 30, 2025
  If your Afore Inverter displays a 'PV1 Over Current' error, it indicates that the PV1 current is excessively high, triggering a protective mechanism. To resolve this: * Power off the inverter, and then restart it. If the issue persists frequently, consider seeking assistance from local distributors.

Why does my Afore HNS2500TL-1 show PV Volt High?
- D
  david58Sep 2, 2025
  The 'PV Volt High' error on your Afore Inverter means the DC input voltage from your PV strings exceeds the maximum allowable value. To fix this, reconfigure the PV strings to reduce the DC input voltage by decreasing the number of PV strings. If problems persist, contact local distributors for further assistance.

Why does my Afore HNS2500TL-1 show PV Volt Low?
- S
  Sarah AndersonSep 4, 2025
  The 'PV Volt Low' error on your Afore Inverter indicates that the DC input voltage from the PV strings is below the minimum required value. To address this, reconfigure the PV strings to increase the DC input voltage by increasing the number of PV strings. If the issue continues, contact local distributors for additional support.

How to fix Bus High Fault/Bus Fault on Afore Inverter?
- J
  Jane BrownSep 9, 2025
  A 'Bus High Fault' or 'Bus Fault' on your Afore Inverter can be caused by high PV input voltage or a poor AC side connection. To resolve this, check that the PV input voltage is within the acceptable range: 450Vdc for models up to 3.0kW, or 500Vdc for models up to 5.0kW. Also, ensure the AC connector and circuit breaker are well connected.
