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 Goodwe GW8K-ET ET did not start up with PV only?
If your Goodwe Inverter ET doesn't start up with PV only, ensure the PV voltage is greater than 180V (230V is needed to enter on-grid mode). Also, verify that the polarities (+/-) are correctly connected between the ET and PV panels and not reversed.
