warnings, beeping, shutdowns, and potential recoveries) are already set and fixed in the factory and
cannot be changed. The only exception is the setting for either enabling or disabling the Power Save
feature. In order to change the power save setting, proceed as follows.
Default Factory Setting:
"PS0" = Power Save feature is disabled.
Setting the Power Save Feature:
The power save feature allows you to reduce the no-load current draw from the battery when an AC
load lower than 10W is plugged into the inverter's GFCI outlet.
To either enable or disable the Power Save function, push and hold the "Power/Select" button for 5
seconds to enter the Power Save select mode. Then, the display shows the present setting ("PS0"
= Power Save disabled, "PS1" = Power Save enabled).
If you wish to change the setting, push again the "Power/Select" button once to change to the other
setting. You can swap both settings by pushing the "Power/Select" button repeatedly within 5 sec.
The unit will automatically exit the select mode after 5 seconds touching the "Power/Select"
pushbutton.
6. TROUBLESHOOTING
Please note any possible error code displayed on the main unit and review the "Understanding the
Error Codes" in section 4. Then, refer to the following table.
Problem
No AC Output. All the
LEDs and the display
are off.
No AC Output. Status
indicator is Amber
AC Output is turning
ON and OFF briefly
(pulsed)
*About how to reset the GFCI outlet: All GFCI's contain a lockout feature that will prevent RESET if there is no
power being supplied continuously to it. Therefore, make sure: a) To unplug all the AC loads. b) The inverter is
powered on before attempting to reset its GFCI receptacle. c) The Power Save mode is DISABLED ("PS0"), so
that the inverter is providing continuous (and not pulsed) AC Power to the GFCI outlet input. If necessary check
the section 5 to change from PS1 (Power Save enabled) to PS0 (Power Save disabled).
Possible Cause/Condition
The unit is off.
No power is coming into the
unit.
Check error code on display
GFCI outlet is tripped
(120V model only)
Power Save function is
enabled "PS1" and the load
being connected to the unit is
less than the threshold setting
(<10W)
Turn the unit ON (Press and hold the "Power/Select"
button for a second until hearing a beep)
Check if the DC Fuse or the DC Disconnect switch (if
installed) is either blown or turned OFF.
Verify the error condition and make correction
Check load for Ground Fault or Neutral-Ground
bonding on the load side, and reset the GFCI*
If you want the Power Save feature enabled (PS1) just
keep it that way and wait for a total AC load over 10W
of power. Otherwise, disable the Power Save function
by changing the unit setting from "PS1" to "PS0" as
explained in section 5 of this manual
