How do I fix a PV Input Overvoltage error on my Goodwe GW10K-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 to do if Goodwe GW10K-ET Inverter 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 causes an Abnormal GFCI 30mA error on a Goodwe GW10K-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.
Why Goodwe GW10K-ET Inverter battery does not charge?
If the battery of your Goodwe Inverter is not charging, ensure that BMS communications are functioning correctly via the PV Master App. Verify that the CT is correctly positioned and connected in the right direction as per the User Manual. Also, check if the total load power significantly exceeds the PV power.
What to do if Goodwe GW10K-ET Inverter 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.
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.
How to fix a Grid Overvoltage error on my Goodwe Inverter?
A 'Grid Overvoltage' error on your Goodwe Inverter indicates that the grid voltage is outside the acceptable range or the duration of high voltage exceeds the HVRT requirement. Here's what you can do: 1. If this occurs occasionally, it might be a temporary grid abnormality. The inverter should automatically recover once the grid returns to normal. 2. If it happens frequently, check if the grid voltage is within the permissible range. If it exceeds this range, contact your local power company. 3. Also, ensure the AC circuit breaker and output cables are securely and correctly connected.
What to do if my Goodwe GW10K-ET Inverter shows 'Low Insulation Res.'?
A 'Low Insulation Res.' error on your Goodwe Inverter typically means one of two things: either the PV string is short-circuited to PE, or the PV system is in a moist environment with poorly insulated cables. To resolve this: 1. Check if the resistance of the PV string to PE exceeds 50k?. If not, identify and fix the short circuit. 2. Verify that the PE cable is correctly connected. 3. If the resistance drops on rainy days, reset the ISO via the SolarGo app.
Why is my Goodwe 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.
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.
