Solution
The unit is off.
Turn the unit ON (Press and hold the “Power/Select”
button for a second until a beep is sounded)
No AC Output. All

No power coming into unit.
Check if the DC Fuse or the DC Disconnect switch (if
installed) is either blown or turned OFF.
Check error code on display
Verify the error condition and make correction
No AC Output.
Status LED is in
Amber
GFCI on 120V model
(SW2420) is tripped
Check load for Ground Fault and reset the GFCI
AC Output is
turning ON and
OFF every few
seconds
Load Sense function is
enabled and Load connected
to unit is less than the
threshold setting. (<10W)
Disable Load Sense function by changing the unit
setting or increase the AC load connected to unit to
>10W
