Application Note – SolarEdge TerraMaxTM Inverter Isolation Fault
In photovoltaic systems with a transformer-less inverter, the DC is isolated from the Ground. Modules with defective module isolation, unshielded wires, defective power optimizers, or an inverter internal fault can cause DC current leakage to the Ground (PE - protective earth). Such a fault is also called an isolation fault.

The first part is the power optimizer, which handles DC to DC and optimizes or conditions the solar panel''s power. There is one power optimizer per solar panel, and they keep the flow of energy equal. For example, with a standard string inverter, if one solar panel produces less energy, all the solar panels in that string will produce less energy.
