What should I do if my Delta Inverter shows a 'Ground Fault' error?

If your Delta Inverter displays 'E34: Ground Fault', check the insulation of the solar inputs. Also, check the capacitance and dry the PV panel if necessary. If the issue persists, check the detection circuit inside the inverter. This could be caused by a PV array insulation fault, large PV array capacitance between Plus to Ground or Minus to Ground or both, or a detection circuit malfunction.
