What to do if my Growatt Inverter shows 'PV Voltage High'?
If your Growatt Inverter displays 'PV Voltage High', it means the DC input voltage is exceeding the maximum tolerable value. Immediately disconnect the DC switch.
What causes 'No AC Connection' error in Growatt 5500MTL-S Inverter and how to fix it?
The 'No AC Connection' error on your Growatt Inverter indicates that there is no utility grid connected or a utility grid power failure. Check the AC wiring.
Why does my Growatt Inverter display 'AC V Outrange'?
The 'AC V Outrange' error on your Growatt Inverter means the utility grid voltage is out of the permissible range. Check the grid voltage. If the error persists despite the grid voltage being within the acceptable range, contact Growatt.
What does 'AC F Outrange' mean on my Growatt 5500MTL-S Inverter?
The 'AC F Outrange' error on your Growatt Inverter indicates that the utility grid frequency is out of the permissible range. Check the grid frequency. If the error continues even when the grid frequency is within the acceptable range, contact Growatt.
What does Error 111 mean on a Growatt 5500MTL-S, and how do I fix it?
Error 111 on a Growatt Inverter indicates a PE abnormality. Here’s how to troubleshoot: * Check the PE line to ensure it has good contact. * Verify that the L and N lines are not reversed. * Restart the inverter. If the error persists, contact Growatt.
What does 'Over Temperature' mean on Growatt 5500MTL-S?
The 'Over Temperature' error on your Growatt Inverter indicates that the temperature is out of range. Check the inverter operation state. If the error message is still displayed, please contact Growatt.
What does 'PV Isolation Low' mean on a Growatt Inverter?
The 'PV Isolation Low' error on your Growatt Inverter suggests an insulation problem. Check the following: * If the panel enclosure is properly grounded. * If the inverter is properly grounded. * If the DC breaker is wet. If the error persists after checking these, contact Growatt.
What does Error 102 mean on a Growatt 5500MTL-S, and how can I resolve it?
Error 102 on a Growatt Inverter is a consistent fault indicating that the data received by the Master and Slave processors are different, possibly due to frequent changes in utility grid voltage or frequency. Try restarting the inverter. If the error appears frequently or persists after restarting, check the utility grid. If the error still exists, contact Growatt.
What does 'Output High DCI' mean on Growatt Inverter?
The 'Output High DCI' error on your Growatt Inverter indicates that the output current DC offset is too high. Restart the inverter. If the error message still exists, contact Growatt.
What does Error 121 mean on a Growatt 5500MTL-S Inverter, and how do I fix it?
Error 121 on a Growatt Inverter indicates a communication fault where the Master processor can't receive data from the Slave processor. To resolve this, restart the inverter. If the error message persists, contact Growatt.
