ground fault / leakage. It compares the current sent to the load side and returned
back from the load side. If the returned current is less by more than 5 to 7 mA
(this loss of returned current will be due to ground fault / leakage on the load
side), the switch trips and disconnects the AC load from the AC source. When the
GfCI has tripped due to ground fault / leakage, it can be reset by pressing the
reset button.
for the reset button to operate and reset the GfCI, AC power is required to be
present on the Line Side (input side) of the GfCI. If AC power is not available on
the Line Side (input side) of the GfCI, the GfCI will not reset.
When the GfCI trips due to leakage on the Load Side, the following symptoms
will be seen:
On the GFCI
• The Green LeD light on the GfCI will be switched off
On the Inverter
• Green LeD on the front panel of the inverter will continue to remain
lighted
• Internally, the inverter will still be working normally and the rated AC
output voltage will be available on the internal Line Side of the GfCI,
but not on the external Load Side of the fGCI due to trippped relay in
the GfCI.
On the LCD Display
• Power bar graph is switched off
• backlight is dimmed
• only the DC input voltage is displayed
When the output side of the GfCI outlet of the inverter trips due to ground
fault / leakage on the load side, the inverter will still be operating normally and
AC power will still be available on the Line Side (input side) of the GfCI (but not
on the output side of the GfCI). Thus, “OUTPUT FAULT” message will NOT be
displayed when the GFCI has tripped due to ground fault / leakage on the Load
Side. Use the “reset” button on the GfCI to reset the mechanical switch to the
on position after removing the cause of the ground fault.
