What to do if my Afore Inverter shows 'No Utility'?
- L
  Lindsay CalderonAug 4, 2025
  If your Afore Inverter displays a 'No Utility' error, it could be due to several reasons: a utility loss, the AC side circuit breaker being turned off, a poor connection on the AC side, or an inverter fault. First, if the grid returns to normal, the inverter will restart automatically. If not, replace the AC circuit breaker and check the AC connector for a secure connection. If the fault persists after several restarts, the inverter may need replacement.

  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.

What to do if Afore Inverter shows Over Temperature Fault?
- J
  Jamie TurnerAug 15, 2025
  If your Afore Inverter displays an 'Over Temperature Fault', it may 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. Consider relocating the inverter to a well-ventilated area. If the problem persists, the temperature sensor may need to be replaced.

Why does my Afore Inverter show a Ground Current Fault?
- S
  Seth WoodardAug 22, 2025
  A 'Ground Current Fault' on your Afore Inverter can occur due to poor earthing leading to high leakage current, or if the PV(+) or PV(-) is earthed. To address this: 1. Check the AC output wiring and restart the inverter. 2. Check the PV array wiring.

How to resolve PV Over Fault on Afore Inverter?

  Tracy PierceAug 28, 2025
  A 'PV Over Fault' on your Afore Inverter typically indicates that the PV array's Voc (open-circuit voltage) is too high. You should re-design the PV array configuration. Also, measure the PV array voltage to ensure it matches what the inverter displays.
