What does 'Resid.curr.too.high' mean on my SMA SUNNY TRIPOWER CORE1?
If your SMA Inverter displays 'Resid.curr.too.high > Check generator', the inverter has detected a residual current due to temporary grounding of the PV array. Check the PV system for ground faults.
Why is my SMA SUNNY TRIPOWER CORE1 not connecting to WLAN?
If your SMA Inverter displays 'No WLAN connection possible', ensure that the SSID, WLAN password, and encryption method have been entered correctly. Also, verify that the WLAN router or WLAN Access Point is within range and functioning correctly. If the issue persists, consider using a WLAN repeater to improve the connection.
What to do if my SMA SUNNY TRIPOWER CORE1 Inverter lost WLAN connection?
If your SMA Inverter shows 'WLAN connection lost', ensure that the WLAN router or WLAN Access Point is still active and within range, signaling correct operation. If this message appears frequently, consider using a WLAN repeater to improve the WLAN connection.
Why is my SMA SUNNY TRIPOWER CORE1 Inverter showing a grid fault?
If your SMA Inverter displays a grid fault, check if the grid voltage at the connection point of the inverter is consistently within the permissible range. If the grid voltage is outside the permissible range due to local grid conditions, contact the grid operator.
What to do if my SMA Inverter is waiting for grid voltage and shows a grid failure?
The message 'Waiting for grid voltage > Grid failure > Check AC circuit breaker' on your SMA Inverter may appear if the AC cable is not correctly connected or the country data set is not correctly configured. Ensure that the circuit breaker is switched on, the AC cable is undamaged and correctly connected, and the country data set is configured correctly. Also, verify that the grid voltage at the inverter's connection point is within the permissible range.
What does DC overvoltage mean on my SMA SUNNY TRIPOWER CORE1 and how do I fix it?
If your SMA Inverter shows 'DC overvoltage > Disconnect generator', immediately disconnect the inverter from all voltage sources. Check if the DC voltage is below the inverter's maximum input voltage. If it exceeds the limit, ensure the PV array is correctly rated or contact the PV array installer.
What to do if parameter file is not found on my SMA Inverter?
If your SMA Inverter displays 'Parameter file not found or defective', copy the parameter file to the correct folder again. The parameter file was not found or is defective, and loading the parameter file has failed.
What does 'DC overcurrent' mean on my SMA SUNNY TRIPOWER CORE1 and how to resolve it?
If your SMA Inverter displays 'DC overcurrent > Check generator', and this message is displayed frequently, ensure that the PV array has been correctly rated and wired.
What does 'Insulation failure' mean on my SMA SUNNY TRIPOWER CORE1 Inverter?
If your SMA Inverter displays 'Insulation failure > Check generator', the inverter has detected a ground fault in the PV array. Check the PV system for ground faults.
What does 'PE conn. missing' mean on my SMA SUNNY TRIPOWER CORE1?
If your SMA Inverter displays 'PE conn. missing > Check connection', it means the grounding conductor is not correctly connected. Ensure that the grounding conductor is correctly connected.
