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 ground output of the PV string is grounded in Goodwe Inverter?
If your Goodwe Inverter displays that the ground output of the PV string is grounded, check whether the L cable and N cable are connected properly.
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.
How to check PV input connection on Goodwe Measuring Instruments?
To fix PV input connection problems with your Goodwe Measuring Instruments, confirm that the connections between the ET and PV panels are correctly established.
What to do if Goodwe ET ET does not discharge or output without PV?
If your Goodwe Inverter ET hybrid inverter isn't discharging or outputting when PV is low, several factors could be at play. First, verify that the communications between the ET and Smart Meter are functioning correctly. Ensure that the load power exceeds 150W. If the meter power is above 150W, double-check the Smart Meter and CT connections, including their directions. Confirm that the SOC is greater than 1-DOD. If the battery's SOC is below 1-DOD, it will only discharge once it's charged to (20%+1-DOD/2); you might need to restart the battery for immediate discharge. Finally, check the APP for any set charge times, as the battery prioritizes charging during these periods.
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.
