What to do if my Hoymiles HYT-5.0HV-EUG1 displays Residual Current Fault?

If your Hoymiles Inverter displays a Residual Current Fault, it indicates that the residual leakage current is too high. This can be caused by high ambient humidity; the inverter should reconnect after the environment improves. If the environment is normal, inspect the AC and DC cables to ensure they are well insulated.
