What to do if Goodwe ET shows PV Continuous Hardware Overcurrent?
To address a 'PV Continuous Hardware Overcurrent' error on your Goodwe Inverter, disconnect the AC output switch and DC input switch, then reconnect them after 5 minutes. If the problem persists, contact the dealer or after-sales service.
What to do if Smart Meter & CT connections are not working on Goodwe Measuring Instruments?
To resolve issues with Smart Meter & CT connections in your Goodwe Measuring Instruments, ensure that the Smart Meter and CT are properly connected between the house loads and the grid. Also, make sure to follow the Smart Meter direction sign on the CT.
How to troubleshoot on-grid and backup connections in Goodwe Measuring Instruments?
To resolve on-grid and backup connection problems with Goodwe Measuring Instruments, verify that the on-grid is connected to the power grid and the backup is connected to the loads. Also, check that the polarities (e.g. L1/L2/L3/N) are correctly aligned.
What to do if Goodwe ET Inverter shows Large DC of AC current L1?
A 'Large DC of AC current L1' error on your Goodwe Inverter means that the DC component of the output current exceeds the safety or default range. If the problem is caused by an external fault like a utility grid exception or frequency exception, the inverter will recover automatically after solving the problem.
What to do if Goodwe ET shows PV Continuous Software Overcurrent?
To address a 'PV Continuous Software Overcurrent' error on your Goodwe Inverter, disconnect the AC output switch and DC input switch, then reconnect them after 5 minutes. If the problem persists, contact the dealer or after-sales service.
What to do for Grid 10min Overvoltage on Goodwe ET Inverter?
A 'Grid 10min Overvoltage' error on your Goodwe Inverter indicates that the moving average of the grid voltage in 10 minutes exceeds the safety requirements. If the problem occurs occasionally, the utility grid may be temporarily abnormal, and the inverter will recover automatically after detecting that the utility grid is normal. If the problem occurs frequently, check whether the grid voltage is within the allowed range. Contact the local power company if the grid voltage exceeds the permissible range. If the grid voltage is within the permissible range, modify the grid overvoltage rapid protection threshold after obtaining consent from the local power company.
Why is my Goodwe Inverter showing a Cavity Overtemperature error?
A 'Cavity Overtemperature' error on your Goodwe Inverter can be due to several reasons: 1. The inverter is installed in a location with poor ventilation. 2. The ambient temperature exceeds 60°C. 3. There is a fault with the internal fan of the inverter. To address this, first, check the ventilation and ambient temperature at the installation point. If ventilation is poor or the temperature is too high, improve ventilation and heat dissipation. If both are normal, contact the dealer or after-sales service.
What does Anti-islanding mean on Goodwe ET Inverter?
An 'Anti-islanding' error on your Goodwe Inverter indicates that the utility grid is disconnected, but the grid voltage is maintained due to the loads, according to safety regulations. Check whether the utility grid is disconnected and contact the dealer or after-sales service.
What to do if Goodwe ET Inverter displays Relay Check abnormal?
If your Goodwe Inverter displays a 'Relay Check abnormal' error, disconnect the AC output switch and DC input switch, then reconnect them after 5 minutes. This error can be caused by the relay being abnormal or short-circuited, the control circuit being abnormal, or the AC cable connection being abnormal (like a virtual connection or short circuit).
What causes an Abnormal GFCI 30mA error on a Goodwe ET Inverter?
An 'Abnormal GFCI 30mA' error on your Goodwe Inverter indicates that the input insulation impedance has become low during operation. If this occurs occasionally, it might be due to a cable issue, and the inverter should recover automatically once the problem is resolved. However, if the problem occurs frequently or persists, check whether the impedance between the PV string and PE is too low.
