SolarEdge RESU10H Prime Series Installation Manual page 38

Select the appropriate RCD for correct operation of the installation: An RCD with a
rating of 30 mA may actually trip at a leakage as low as 15 mA (according to IEC
61008). High quality RCDs will typically trip at a value closer to their rating.
Configure the trip voltage of the inverter's internal RCD to a lower value than the trip
current of the external RCD. The internal RCD will trip if the current is higher than
the allowed current, but because the internal inverter RCD automatically resets when
the residual currents are low it saves the manual reset.
