NOTE
SolarEdge inverters can be installed in sites with an alternative power source
such as a generator. SolarEdge requires installing a physical or electronic
interlock, which will signal to the inverter when the grid has been disconnected.
Interlock procurement, installation, maintenance and support are the
responsibility of the installer. Damage to the inverter due to incorrect interlock
installation or use of an interlock that is incompatible with the SolarEdge
system will render the SolarEdge warranty invalid.
For more information on connecting an alternative power source
to SolarEdge inverter, refer to

support-of-voltage-sources.pdf.
All SolarEdge inverters incorporate a certified, built-in Ground Fault Current Interrupter
(GFDI). The GFDI protects against electrocution in case of a malfunction in the PV array,
DC cables, or DC section of the inverter. The GFDI in the SolarEdge inverter can detect
current leakage on the DC side. There are two trip thresholds for the GFDI. The lower
threshold, is used to protect against rapid changes in current leakage - typicaly due to
direct contact by people. The higher threshold, detects slowly rising leakage currents, in
the grounding conductors and limit the currents to ensure fire safety. The default
current value for high speed personnel protection is 30mA. The default current value for
lower speed fire safety, per unit, is 300mA. The same detection is also used for
measuring the resistance of the insulation of the PV array for verifing it is higher than a
pre-configured value.
