What to do if Goodwe GW5KL-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.
Why is my Goodwe GW5KL-ET Inverter showing a utility loss?
If your Goodwe Inverter is showing a utility loss, it could be due to a failure in the utility grid power or because the AC cable is disconnected, or the AC circuit breaker is off. Once the grid power supply is restored, the alarm should automatically clear. Ensure the AC cable is securely connected and the AC circuit breaker is turned on.
What to do if Goodwe Inverter 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.
How to check battery connections on Goodwe Measuring Instruments?
To solve battery connection issues in Goodwe Measuring Instruments, confirm that the connections between the ET and the battery are properly established.
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 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.
How do I fix a PV Input Overvoltage error on my Goodwe GW5KL-ET?
A 'PV Input Overvoltage' error on your Goodwe Inverter means that too many PV panels are connected in series in the PV string. Check the serial connection of the PV array, ensuring that the open circuit voltage of the PV string does not exceed the inverter's maximum operating voltage.
What causes an Abnormal GFCI 30mA error on a Goodwe GW5KL-ET?
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.
