What happens if a PV string circuit does not have a ground fault?

A PV string circuit without a ground fault will have open circuit voltage (Voc) between positive and negative conductors. It will have zero volts from positive to ground and from negative to ground. When a ground fault is present, measurement will show Voc between positive and negative conductors.

What is a PV ground fault?

PV ground faults have a clear consequence. The fault makes the solar inverter, or combiner box shut down completely. Production is only reestablished, when Riso becomes sufficiently high again. For a residential PV array, a ground fault typically takes down 2 or 3 strings.

Why do residential PV arrays have ground faults?

In some cases, PV ground faults are caused by modules with water intrusion, or by other more rare and exotic faults. The cost associated with residential ground fault mitigation is often higher than the system owner appreciates. This is one of the reasons why some residential PV arrays are not properly maintained and serviced.

How to check a PV system for ground faults?

Only use measuring devices with a DC input voltage range of 600 V or higher. In order to check the PV system for ground faults, perform the following actions in the prescribed order. The exact procedure is described in the following sections. Check the PV system for ground faults by measuring the voltage.

What causes a ground fault in a PV inverter?

PV ground faults can periodic and intermittent. Typically moisture in the morning will induce an intermittent faults. The energy production from a given string will be switched off until the equipment dries up, and the inverter goes back online. The emazys Z200 has a build in ground fault detector.

What happens if a solar inverter is grounded?

In a solar photovoltaic system, if a ground fault occurs, the inverter will display a “GROUND-FAULT” alarm when it starts running, and the alarm code is 1033H.
