SolarEdge SE Series User Manual

Selecting a Residual Current Device (RCD)
In every PV installation, elements of the system contribute to current leakage to
protective earth (PE).
IMPORTANTSAFETYFEATURE
All SolarEdge inverters incorporate a certified internal RCD (Residual Current
Device) to protect against possible electrocution in case of a malfunction of
the PV array, cables or inverter (DC). The RCD in the SolarEdge inverter can
detect leakage on the DC side. There are 2 trip thresholds for the RCD as
required by the DIN VDE 0126-1-1 standard. A low threshold is used to protect
against rapid changes in leakage typical of direct contact by people. A higher
threshold is used for slowly rising leakage currents, to limit the current in
grounding conductors for fire safety. The default value for higher speed
personnel protection is 30mA, and 100mA per unit for lower speed fire safety.
If an external RCD is required by local regulations, check which type of RCD is required
for the relevant electric code. Install the residual-current device (RCD) in accordance
with the applicable local standards and directives.
