• Green LED
“CHArGer”
(7, Fig 3.1) is OFF
• Green LED
“INVerTer”
(8, Fig 3.1) is ON
• Charger has stopped
• Grid voltage is avail
-
able at the power cord
• AC output is available
5A fuse (5, Fig 3.1) feed
-
ing the Charger Section
has blown. As a result,
Grid AC Input Detect
Circuit in the Charger
Section has detected
Grid AC input failure re-
sulting in transfer from
Grid to Inverter
Replace 5A fuse (5,
fig 3.1). If fuse blows
again, the battery
Charger Section is likely
to be defective. Call
Tech Support
• Charger has stopped
• Grid voltage is NOT
available at the
power cord
• AC output is available
Grid has failed or
the breaker / switch
supplying input to the
GfCI protected Grid AC
outlet has tripped or has
been switched off. As
a result, Grid AC Input
Detect Circuit in the
battery Charger Section
has detected Grid AC
input failure resulting
in transfer from Grid to
Inverter
Confirm if Grid has
failed. If not, check if
the breaker / switch
supplying the GfCI pro-
tected Grid AC outlet
has tripped or has been
switched off
• Green LED
“CHArGer”
(7, Fig 3.1) is OFF
• Red LED “FAULT”
(9, Fig 3.1) is ON
• Charger has stopped
• Grid voltage is NOT
available at the
power cord
• AC output is NOT
available
There is leakage or
Neutral to Ground bond
on AC load side.
• First, the GFCI
protected AC outlet
supplying Grid power
will trip. As a result,
Grid AC Input Detect
Circuit in the Charger
Section will detect
Grid AC input failure
resulting in transfer
from Grid to Inverter
• Once the load is
transferred from Grid
to the Inverter, the
Inverter will shut
down due to leakage
or Neutral to Ground
bond on the load side
• Check for leakage /
Neutral to Ground
bond on the AC load
side
• Reset the GFCI pro
-
tected AC outlet sup-
plying Grid power
• The Inverter Section
will remain latched
in off condition.
To reset, switch off
the Inverter oN/off
Switch (3, Fig 3.1),
wait for 3 minutes
and switch oN again
