What causes 'PV Over Voltage' on a Goodwe HT Inverter and how to fix it?
The 'PV Over Voltage' error on your Goodwe Inverter means that too many PV modules are connected in series, causing the open-circuit voltage to exceed the operating voltage. Check if the PV string input voltage matches the value displayed on the LCD. Also, verify that the PV string voltage meets the maximum input voltage requirements.
How to fix an 'Over Temperature' error on a Goodwe HT?
If your Goodwe Inverter is showing an 'Over Temperature' error, it may be installed in a location with poor ventilation, the ambient temperature might be exceeding 60°C, or there could be a fault with the internal fan. Check the ventilation and ambient temperature around the installation point. If ventilation is poor or the temperature is too high, improve the ventilation and heat dissipation. If both are normal, it may indicate a need to contact support.
What causes a Vac Failure on a Goodwe Inverter?
A 'Vac Failure' on your Goodwe Inverter indicates that the utility grid voltage is outside the allowed range. To resolve this, ensure that the grid voltage is within the permissible limits and that the phase sequence of the AC cables are correctly connected, and the PE cable is properly and firmly connected.
What does ISO Fail mean on a Goodwe Inverter?
An 'ISO Fail' error on your Goodwe Inverter suggests that the PV system is short-circuited to the ground or is in a moist environment with poor insulation. Check the PV input cables for any breaks, ensure the module frames and metal bracket are securely grounded, and verify that the AC side is properly grounded.
What does 'Ground I Fail' mean on my Goodwe Inverter, and how can I resolve it?
The 'Ground I Fail' error on your Goodwe Inverter indicates that the input insulation impedance to the ground decreases during operation. Check if the inverter's working environment meets the requirements; for instance, high humidity on rainy days can cause this issue. Also, ensure that the components are properly grounded, and the AC side is correctly grounded.
What does 'DC Bus High' mean on a Goodwe Inverter, and how do I fix it?
The 'DC Bus High' error on your Goodwe Inverter usually indicates an internal fault. Make sure that the software is the latest version. Restart the inverter to check whether it can work properly.
What does 'Night BUS Fault' mean on my Goodwe Inverter?
If your Goodwe Inverter displays the 'Night BUS Fault' message, it means there is a problem with the utility grid power or the AC cable is disconnected, or the AC breaker is off. To attempt a fix, disconnect the AC output switch and DC input switch, wait 5 minutes, then reconnect them. If the issue persists, contact your dealer or after-sales service.
What to do if my Goodwe HT Inverter displays 'DC-SPD'?
If your Goodwe Inverter shows 'DC-SPD', it indicates that the inverter was struck by lightning. As a first step, improve the lightning protection around the inverter. Then, disconnect the AC output switch and the DC input switch, wait 5 minutes, and reconnect them. If the problem continues after these steps, contact your dealer or after-sales service.
What causes SPI Comm Fail on Goodwe HT?
A 'SPI Comm Fail' error on your Goodwe Inverter could be due to the chip not being powered on or a wrong chip program version. Disconnect the AC output switch and DC input switch, then reconnect them after 5 minutes. If the problem persists, further assistance may be needed.
What causes an ExFan Failure on a Goodwe Inverter?
An 'ExFan Failure' on your Goodwe Inverter can be due to an abnormal fan power supply, a mechanical issue, or the fan aging and becoming damaged. Disconnect the AC output switch and DC input switch, then connect them again after 5 minutes. If the problem continues, further assistance may be needed.
