Preparing for Installation
Typical Wiring block diagram of the Power Inverter:
12V Battery Bank:
The use of a deep cycle battery is highly recommended for power inverter application
For battery sizing, you need to identify what you wish to operate, and for how long. It is
recommended that you purchase as much battery capacity as possible. See more on Battery
Run Time in Section 4.
DC Fuse or Circuit Breaker:
DC-rated fuse or DC-rated circuit breaker connected along the DC positive line is required.
1000W model
2000W model
3000W model
DC Fuse/Circuit Breaker Rating
150Adc
300Adc
350Adc
Based on the size of your 12V Battery Bank, determine the overall short circuit current rating
of the battery bank from the battery manufacturer. The fuse or circuit breaker chosen has to be
able to withstand the short circuit current that may be generated by the battery bank. Typically
an ANL/Class-T fuse & holder is used for battery bank capacity lower/over 500Ah respectively
For Marine application, the over-current protective device needs to be installed within 7 inches
(17.8cm) from the battery positive terminals.
DC Disconnect Switch:
Use a DC Disconnect Switch with the same or higher rating of the selected DC fuse or DC
circuit breaker. Use ignition protected switches when required by local codes.
The DC Disconnect Switch is used to disconnect the DC power between the unit and the
battery bank positive during service, maintenance or troubleshooting.
DC Input Cable Size:
All DC cables require insulated multi-strand low resistance cable.
The DC cables must be copper and rated to 105℃minimum.

1000W unit
AWG # 2
< 5 feet
2000W unit
AWG # 2/0
< 5 feet
3000W unit
AWG # 4/0
< 5 feet
Caution: Use of a wire with a thinner gauge or a longer length, may cause the inverter to shut down
under heavy load due to under-voltage shutdown, and may also melt the cable insulation and catch fire
and can result in death or serious injury. The proper cable gauge should also match the rating of the DC
fuse used (i.e. never use a fuse with a current rating higher than the maximum continuous one of the
cable).
Important: The recommended cable length is limited to 5 feet or less. This is due to the consideration of
voltage drop between the battery and the unit. For longer cables, a thicker gauge is required to
compensate for additional voltage drop (see the following table)
Grounding Cable Size:
Important: The unit has to be grounded properly before use. There are two ground (GND)
terminals bonded to the same metal chassis, one for the AC safety GND and another for the DC
GND (which is thicker due to the very high DC currents involved). The former is a Phillips screw
located beside the AC-Input terminal, and the latter is a stud terminal with a 10mm nut and lock
washer located close to the back panel.

For Marine application, the DC grounding cable size may be one size thinner than the
minimum size conductor required for the DC current-carrying conductors (i.e. the positive and
negative wires).
For Recreational Vehicle or Caravan application, the unit has to be grounded to the vehicle
chassis with a minimum AWG #8 copper conductor.
Notes: * The suffix "i" stands for International units (@ 230Vac, single-phase, 50Hz) with different
outlets as per the specific country. **For battery banks with total capacity under 500Ah the most
affordable ANL fuse type can be used with its corresponding fuse holder; otherwise, use Class-T type.
AC Input Source and AC Branch Breaker:
Standard AC-Input wire is required for all the AC connections between the AC source & the
AC Input port, and the AC Output ports to load.
For 120V model and maximum Bypass power rating, a minimum of #10 AWG AC wire is
required. An external 30A branch circuit breaker is also required in between the AC Input
source and the unit AC Input port.
For 230V model and maximum Bypass power rating, a minimum of #14 AWG AC wire is
required. An external 16A branch circuit breaker is also required in between the AC Input
source and the unit AC Input port.
Important: Follow the local electrical code when you connect the unit to any AC source.
Installing the Inverter System
WARNING: Electrical Shock Hazard
The unit ‘On/Off’ switch does not disconnect the DC power from the battery. Use the DC
Disconnect Switch or disconnect the DC input cables to disconnect the DC power from
the battery before working on any circuits connected to the unit. Failure to follow these
instructions can result in death or serious injury.
Installation:
Choose an appropriate mounting location.
For indoor use, the unit can be mounted in any direction except with the fans (DC-Input) panel
facing downwards (when mounted vertically). This is required for a better thermal dissipation
and to avoid any potential fire hazard in the improbable case a melted material passes through
the fan holes reaching the floor if something goes wrong inside the inverter. This is mandatory
by the standard bodies.

For 120V model:
The AC Output has three types of AC load connections:
1) The provided AC Output GFCI receptacles (except for the SWXFR1230 which does not
have GFCI but regular NEMA 5-20 receptacles instead):
This configuration does not require any AC Output wiring installation. Just plug the AC loads
into the provided AC Output receptacles. During the Bypass mode, the AC output is limited
to the rating of the receptacle being used and its corresponding thermal breaker protection
(15A for 1000W model, and 20A for both 2000W and 3000W models).
2) The provided hardwired AC Output terminal (Port 2) with GFCI protection (except for the
SWXFR1230 which does not have GFCI outlet):
To access Port 2, remove the plastic white AC compartment cover located on the front panel
of the unit. Hardwire the AC load (outlet, distribution panel, etc.) to the AC Output port 2.
Please verify the LIVE ‘L’and NEUTRAL ‘N’connection on the AC Output port.
Note: This AC Output Port 2 is connected directly to the output (load side) of the GFCI outlet,
having the same power rating. This hardwired port is under the influence of the GFCI
socket’s “Test” and “Reset” buttons.
3) The provided hardwired AC Output terminal (Port 1) –with no GFCI Protection:
To access Port 1, remove the plastic white AC compartment cover located on the front panel
of the unit. Hardwire the AC load (outlet, distribution panel, etc.) to the AC Output Port 1.
Please verify the LIVE ‘L’and NEUTRAL ‘N’connection on the AC Output port.
4) Connect the AC Output Ground wire(s) to the Common AC Ground terminal inside the wiring
compartment.
Note: During Battery Power (Inverter) mode, the total AC Output is limited to 8.3A / 16.7A / 25A
of continuous current for the 1000W / 2000W / 3000W model respectively.
For 230V model (SWXFR1230i):
The AC Output has two types of AC connections:
1) The provided AC Output receptacle for AC load connection:
This configuration does not require any AC Output wiring installation. Just plug the AC loads
into the provided AC Output receptacles. During the Bypass mode, the AC output is limited
to the rating of the receptacle being used and its corresponding thermal breaker protection
(16A on EU model, 13A on UK model and 10A on AU model).
2) The provided hardwired AC Output terminal:
To access it, remove the plastic white AC compartment cover located on the front panel of
the unit. Hardwire the AC load (outlet, distribution panel, etc.) to the AC Output terminal.
Please verify the LIVE ‘L’ and NEUTRAL ‘N’connection on the AC Output terminal.
Important: If an RCD (Residual Current Detector) is used for the AC Output connection, an
AWG #14 jumper wire is required to connect GP1 and GP2. This is used to ground the
Neutral pin of the inverter to the chassis.
3) Connect the AC output Ground wire to the Common AC Ground terminal inside the wiring
compartment.
Note: During Battery Power (Inverter) mode, the total AC Output is limited to 4.3A / 8.7A / 13A of
continuous current for the 1000W / 2000W / 3000W model respectively.
Remote Display Connection:
The display panel is detachable. To install it remotely in a different location use the provided
25 feet long 6 pins RJ12 “rollover” cable.
Remove the 2 screws at the front of the Display Panel and disconnect the short RJ12 cable
from the unit.

Page 11
Install the 6-pin RJ12 cable in your desired location and connect the RJ12 cable to the unit
and the other end of the cable to the Display Panel. See appendix II for more details.
Test the Inverter Connection:
Turn the DC disconnect switch ON to provide battery power to the unit.
Turn the external AC Branch Breaker ON to provide AC Input power to the unit. The display on
the panel should turn on automatically showing “888” briefly, then the software revision
number of the detachable panel and the main unit (e.g. “r0.4” and “u1.6” respectively), before
finally passing from the initiation routine to normal operation showing the battery voltage and
providing AC-Output power.
Once the display starts showing the battery voltage (with AC-Input power available) the
‘Status’LED will turn green to indicate that the unit is in Bypass mode, which means the AC
output is running from the AC input source. If the unit is set to “PS1 (”factory default) it will take
about 20 sec for entering Bypass mode. In that case, meantime the “Status” LED remains
flashing amber to indicate the unit is running in Battery (Inverter) mode and is going to pass to
Bypass soon (within a 20 sec period). If the unit is set to “PS4”, it has to be turned on manually
by pushing the “Power” button (see Feature Setting section for more details).
Once the “Status” LED goes solid green, disconnect the AC input source by turning the exter-
nal AC Input Branch Breaker OFF. Doing so, the ‘Status’LED on the display changes immedi-
ately from solid green to solid amber, to indicate the unit is running in Battery (Inverter) mode.
Both AC output and 5V USB are now available and the unit is running on battery power.
Plug in a small AC load like a 40W table lamp or small appliance to the AC socket to verify AC
is available.
The unit is successfully installed and functioning properly.
Test the GFCI monthly: (120V model only)
Use the following instruction to perform a monthly test of the AC Output GFCI Socket to ensure
the GFCI is functioning properly.
Turn the unit on and plug a small AC load (e.g. a light bulb) to the AC Output GFCI Socket.
Check that the AC load is ON.
Press ‘TEST’ button and observe a clicking sound. Check that the AC load is turned off.
Press ‘RESET’ button and check that the AC load is back ON again.
4. UNIT OPERATION
Auto Backup Mode (whatever “PS” setting except “PS0”):
The unit is fully automatic. When utility power is available, the unit is running in AC Bypass mode.
AC output is supplied from the utility. When there is a power failure from the utility or an AC
source is not available, the unit will run on battery power and the inverter will generate sinewave
AC output to maintain and operate the load continuously (With ‘PS2’setting, there is a minimum
of 10W AC-Load sense threshold for the inverter to fully turn on).
Non-Backup Mode (with “PS0” setting)
Same as Auto Backup Mode but when there is a power failure from the utility or the AC input
source is not available; the inverter will not turn ON automatically. To turn the inverter on, you
have to get into the setting mode and change the ”PS” setting from “PS0” to “PS1” or others.
See more details on Inverter Setting.

AC Load on Inverter
Although the Power Inverter can provide high surge power up to two times the rated
(continuous) output power, some high surge loads like sump-pumps, heavy duty motors etc.
may still trigger the inverter protection system even though the load falls within the power rating
of the inverter. A higher power Inverter is required for these appliances.
Important: For the SWXFR1230 (120VAC model) unit, a single appliance that requires more
than 20A (>2400W) of AC power, has to be hardwired directly to the AC Output Port 1. Both AC-
Output receptacles are limited to 20A of maximum continuous current.
Estimated Run Time
Following run times are estimates for reference, based on using different battery bank sizes.
Actual run times may vary.
Important: Power Drain from DC Battery Bank.
When the SWXFR1230 and SWXFR1230i are running in AC Bypass mode, there is a DC
current drain from the battery bank around 700mA. In order to avoid draining the battery bank
down, a battery charger with sufficient power is required to maintain the battery bank voltage.

5. FEATURE SETTING
To understand more about the unit features, read the following section and follow the instructions
to make changes to the desired setting.
Default Factory Setting:
PS (Power Sources): PS1 - inverter enabled in standby mode with load sense off
AL (Alarm beeper): AL1 - alarm enabled
Sd (UV shutdown): SdL - Under voltage shutdown set to low setting
Understanding the Unit Settings
Inverter Setting
PS0
The inverter is disabled and the AC-Input shore power passes through the internal
transfer switch to the AC-Output. When the shore power is disconnected, the unit does
not provide AC backup function, and the display automatically turns off in about 30
seconds. Use this mode when a manual backup start is desired.
Note: For enabling the inverter, the PS0 setting has to be changed to another different one.
PS1
The inverter is enabled and provides AC backup when utility power is not available
PS2
The inverter is set to standby mode with power save (load sense) mode ON. The unit
will provide AC backup function only when utility power is not available AND the load
connected to the output is >10W. Once the unit is ON, it will automatically return to
power save (load sense) mode when the connected AC load drops below 3W (there is
an hysteresis of about 7W)
Note: During the power save “PS2” mode, the Inverter will turn ON every few seconds briefly (for
a few AC cycles) to check if there is a load drawing more than 10W of power. Therefore, any load
>10W will start getting power within a random period in between 0 to 10 sec.
PS3
Not Available

Page 14
Note: In PS0, PS1, and PS2 settings, the unit turns on automatically when getting shore power.
Once having shore power, the unit cannot be turned off. To do so, you have to first disconnect
the shore power (forcing Inverter mode) and then push the Power button.
PS4
Same function as PS1 and the ‘Power’button can be used to turn the AC Output ON
and OFF, even with the AC-Input power being present in Bypass mode. When the unit
is manually turned off in Bypass mode using the ‘Power’button, the display remains
ON showing the battery voltage and the ‘Status’LED turns off.
Note: In the PS4 setting, the AC-Output always can be turned On/Off manually using the Power
button. However, for a complete shutdown (including the lights and display), you have to first
disconnect the external AC-Input power and then push the Power button. When the AC-Output is
turned off, the condition remains memorized, even after a blackout and blackout-recovery. This is
done to be consequent with the last power On/Off action the user did manually on purpose
PS7
Reserved for the manufacturing process, and should not be available. Otherwise,
change it to another setting to start working and to avoid its appearance anymore.
Battery Under Voltage Setting
SdL
Battery under-voltage setting is set to LOW (setting used for normal operation)
Under-voltage alarm: 11.0 Vdc
Under-voltage alarm recovery: 11.3 Vdc
Under-voltage shutdown: 10.5 Vdc
Under-voltage shutdown recovery: 12.0 Vdc
SdH
Battery under-voltage setting is set to HIGH (setting to avoid battery getting over
discharged when connected to a car start/crank battery)
Under-voltage alarm: 12.1 Vdc
Under-voltage alarm recovery: 12.3 Vdc
Under-voltage shutdown: 11.8 Vdc
Under-voltage shutdown recovery: 12.6 Vdc
Alarm Setting
AL0
Fault and the warning audible alarm is disabled. The display panel only shows error
code and the audible alarm will not sound.
AL1
Audible alarm will sound when fault or warning occurs.
Manufacturing Default
Fd
Shortcut to reset all the settings to the manufacturing default settings (PS1, SdL, AL1)
Enter the Function Menu for unit setting:
To enter the unit Function Menu, press and hold “Power” and “Select” buttons together for
about 5 seconds until a beep is sounded.
When you are in Function Menu:
Press the ‘Power’button for 1 second to toggle between different Functions Menu like ‘In’,
‘Sd’, ‘AL’, and ‘Fd’etc.
Press the ‘Select’button for 1 second to enter Individual Function Set Menu and you can
make changes to the settings.
The unit will EXIT the Main Menu automatically if ‘Power’and ‘Select’buttons are not
triggered for more than 5 seconds.
When you are in Individual Function Set Menu:
Press the ‘Select’button for 1 second to toggle between different setting values.
Press the ‘Select’button for 5 seconds to set selected setting and exit to next Main Menu.

6. TROUBLESHOOTING
To troubleshoot the unit, please note the error code displayed on the main unit and review
“Understanding the Error Codes” in section 4.
Problem
Possible Cause/Condition
Solution
AC Output turns
ON and OFF
briefly (pulses)
Power Safe mode (“PS2”)
enabled and AC load <10W
The load connected should be below the AC load
sense threshold of 10+/-2.5W, so power will be
pulsed every few sec. for checking the load power.

Page 15
No AC Output.
All the LEDs and
the display are off.
The unit is off
Note: The power button
On/Off action takes place at
its release moment and after
a “beep” is heard
If the unit is set to “PS4”, turn the unit ON by
pressing the “Power” button. In all other “PS”
settings, the unit should always turn on automatically
after the AC-Input power is connected and the
initiation routine finished (about 6 sec later)
No power coming into the
unit
Check the battery DC fuse, the Disconnect Switch (if
installed), the AC Input Source, and the AC Input
Breaker being perhaps tripped or turned OFF
No AC output at
the AC GFCI
outlet and Port 2
(120V models
except
SWXFR1230) or
at the AC Output
outlet (230V
model). Status
LED is Green or
Amber ①
The GFCI on 120V models is
tripped
Check load for Ground Fault and reset the GFCI.
Make sure the loads do not have the Neutral and
Ground bonded as explained in ③
If no load plugged into the GFCI, there could be
humidity inside it. The GFCIs, in general, are very
sensitive to humidity. Try drying it with a hairdryer
and make sure to use the unit indoors /dry-environ.
Note: GFCIs contain a lockout feature that will prevent RESET if there is no power
being supplied to it. Therefore, make sure to force Bypass mode or do not have
either PSO or PS2 setting when in Battery (Inverter) mode, before resetting
The unit thermal breaker
tripped
Check AC loads and reset the thermal breaker or
breakers
No AC Output.
Status LED is red
The unit shut down; check
error code shown on display.
Verify the error condition and make correction. See
the corresponding error meaning table
During AC Input
Power Outage,
there is no AC
Output power
when battery
power is
available.
The unit is set to “Non-
Backup” mode (“PS0”) and
AC Input Power is not
available.
Change the “PS0” setting to a different setting if you
want to turn the inverter ON.
With “PS0” setting, the inverter is completely OFF.
When the AC Input Power is not available and the
“Power”button is press once, the display and LEDs
stay working for about 30 sec only. With this setting,
the unit will provide AC Output Power only when the
AC-Input Power is available.
AC Output only in
Hardwired Port 1
(120V model) or
Hardwired Port 2
(230V model)
Same as in ①
AC Output Port 1 on 120V models or Port 2 on 230V
models is connected directly to the inverter output.
This Port is not under the tripping influence of either
the GFCI on 120V models (except SWXFR1230) or
any thermal breaker on the unit.
The unit cannot
be turned off
using the power
button when in
“Bypass” mode
This is normal. The unit has
“PS1’ (factory default)
setting. Use the procedure
on the right to turn the unit
Off.
Note: The power button
On/Off action takes place at
its release moment and after
a “beep” is heard
To turn the unit off while in Bypass (pass-through)
mode, first of all, disconnect the AC-Input that feeds
the unit to force entering into Battery (Inverter)
mode. Then push and hold the power button for 1
sec. (after hearing a beep) to turn the unit off.
Set unit to PS4, so the Power button can be used to
turn the unit Off during Bypass or Inverter mode,
without the need of turning Off the shore power first.
“E01” or “E05”
alarm in Bypass
(pass-through)
mode
(SWXFR1210
/1220/1210i
/1220i only) ②
The alarms indicate the
battery voltage is low or the
battery is not connected at
all. However, the unit
continues supplying AC-
Output power in spite of
those alarms (you may need
to wait up to 20 sec. for the
Bypass mode to start).
Charge and/or connect the battery bank or disable
all the audible alarms with the “AL0” setting.
Note: The unit has a small DC power supply to keep
its control electronics working even after
disconnecting the battery. However, do NOT use the
unit without the battery connected; otherwise it can
get hot (perhaps triggering the “E12”
error,message). This is because the 12Vdc fans of
the unit are fed by the battery.

Page 16
DC voltage is
measured at the
DC terminals
without the battery
being connected
(SWXFR1210
/1220 /1210i
/1220i only)
This is normal. The voltage
is supplied by a little built-in
power supply with current
limiting protection.
If the DC-Input terminals of the unit are connected to
a common DC bus being shared by other DC loads,
a 12V back feeding to those DC loads can occur
when the DC bus is disconnected from the common
battery bank. In that case, the corresponding
drawing current may trigger the “E01” or “E05”
alarms as per the problem ②. In cases where that
back feeding is not desirable, consider using a
separate battery bank with a disconnect switch.
Do NOT use the unit with the battery disconnected
to prevent the unit getting hot. The 12Vdc fans of the
unit are fed by the battery
No AC Output.
All the LEDs and
the display are off
even in Bypass
mode
(SWXFR1230 and
SWXFR1230i
only)
SWXFR1230 requires a
battery connected to the DC
input terminals to
maintaining the unit working
properly.
Keep the battery connected to allow the unit working
properly.
On the other hand and as a consequence of that,
there is a power drain of about 700mA from the
battery bank when the SWXFR1230 is running in AC
Bypass mode. In order to avoid draining down the
battery bank in the medium-long term, a battery
charger or trickle charger with a minimum of 1A is
required to maintain the battery bank voltage.
The thermal
breaker trips even
when the unit is
out of an overload
condition
This happens mainly in
Bypass mode when the
maximum rating of the
thermal breaker on the unit
is exceeded. In the
SWXFR1230 unit, that rating
can be exceeded in Battery
(Inverter) mode as well.
On 120V models except SWXFR1230: For
maximum capacity use the AC Output Port 1 which
is out of the tripping influence of the GFCI Outlet and
the unit thermal breaker. Otherwise, do not exceed
the following current ratings on the receptacles: 15A/
20A for the SWXFR1210/1220 models respectively.
On the SWXFR1230 and 230V models: for
maximum capacity use the AC-Output Port 1 which
is out of the tripping influence of the unit thermal
breaker. Otherwise do not exceed 16A/13A/10A on
the AC outlets in the EU/UK/AU models respectively
or 20A in the case of SWXFR1230 120V model.
The display
doesn’t work as
expected, e.g.
death or showing
steady either
“888”, or “rx.x”
message (where x
= any number),
and the operability
of the unit may be
affected
Some loosed contact or pin-
out problems in the RJ12
detachable display panel
cable
A short (7”) RJ12 cable is used when the detachable
display panel is mounted on the unit (factory
default). Alternatively, a long RJ12 cable is provided
for installing the display panel up to 25 ft. away.
Swap the cable you are using with the other one and
check if it makes some difference.
Check the pin-to-pin conductivity of the cable and
the corresponding pin-out as shown in “Appendix II”
Excessive EMI/RFI interfer-
ence (electromagnetic
induction or electromagnetic
radiation) emitted from an
external source
Avoid running the cable very close to motors, power
contactors/relays, ballasts, transformers, or high
voltage devices. In high noisy environments
consider using metal conduits or a shielded cable
grounded at one end and/or reduce cable length
The GFCI outlet
trips as soon as
the load is
connected to
either Port 2 or
into the outlet.
(120V models) ③
There is a Neutral to Ground
bonding in the load side or in
between the shore power
(e.g. grid or generator) and
the Inverter AC-Output
Locate and remove the Neutral to GND bonding on
the load side. If the output of the inverter is
connected to an existing distribution panel/box,
make sure the Neutral and GND connections inside
the panel/box use separate bus bars, being the
Neutral one isolated from the chassis ground.
Otherwise, consider using the AC-Output port 1

Page 17
“PS” setting differ-
ent to PS0, PS1,
PS2, or PS4
Undefined value reserved for
manufacturing process only.
Someone there forgot to
change it to the PS1 default
Get into the setting mode and set the “PS”
parameter to any of the defined ones, so the unit
starts working and the undefined value will never
appear anymore.
Heavy spark
when connecting
the battery power
This is a normal condition
that occurs when having the
internal DC-Input capacitors
(filter) discharged after the
battery was disconnected for
at least 30-40 sec.
This is due to a sudden high DC surge (inrush)
current that charges the internal big capacitors and
disappears almost instantly (milliseconds) as soon
as the capacitors get charged. Virtually it does not
represent any drawing current from the battery.
The battery input
under-voltage
warning (“E05”)
and/or shutdown
alarm (“E01”)
occurs in advance
even when the
battery voltage
seems to be OK
Make sure you are
measuring the voltage
directly at the DC-Input
terminals of the unit, to
include any possible voltage
drop from the battery to the
unit
Excessive voltage drop in between the battery bank
and the inverter, due to the high resistance of the
DC wires, battery disconnect switch, fuse, or DC
breaker (if any). Make sure to use the recommended
wire’s gauge and length. Try using fuses (or DC
breakers) with very low voltage drop (e.g.
ANL/Class-T type fuses, etc.)
The battery bank has a high
internal resistance, resulting
in a voltage drop
proportional to the DC
current being drawn by the
unit.
Too much battery voltage drop due to excessive
drawing current in relation to the battery bank
capacity. Increase the battery bank capacity (i.e.
adding more batteries in parallel) and/or reduce the
AC loads being fed by the inverter
Battery damaged and not able to keep a good state
of charge. Replace the battery (or batteries)
The battery bank is getting
discharged.
This is normal. The E05 warning (followed by the
E01 shutdown) occurs when the battery bank is
getting discharged. Charge the battery bank.
Make sure to measure the
battery voltage just before
the “E01” battery under-
voltage shutdown occurs in
Battery (Inverter) mode.
Then, compare it with the
corresponding voltage
threshold in the
specifications table. (allow
+/- 5% of tolerance)
Just after the E01 occurs, the battery voltage
increases rapidly because the battery is not under
load condition because the inverter is already
shutdown. This is normal in all the battery banks and
can confuse the user thinking the under-voltage
shutdown that triggers the E01 alarm occurs in
advance at higher voltage thresholds than the ones
specified.
The E05 warning and E01
shutdown alarms occur well
in advance due to the “SdH”
setting
If you do not use the same battery bank for both the
inverter and engine cranking purposes, you would
not need to keep enough battery state of charge. If
so, make sure to set the under-voltage shutdown
threshold to the low and factory default “SdL” setting
(other than the “SdH)” for maximum battery
operating range.

Detachable Display Panel Cable:
The display panel can be installed away from the unit, using the included 25’ RJ12 cable. You
would need to remove the two screws indicated below. Even though the unit can operate with the
cable plugged in whatever direction, we suggest plugging the end with the ferrite bead EMI/RFI
