INSTALLATION
The installation of your inverter is
extremely important. Failure to
follow the recommended
installation instructions may void
your warranty. If in doubt, ask
your supplier.
After unpacking the SA41, check
for any damage which may have
occurred during transit. If there are
any signs of damage, contact your
supplier immediately.
The inverter must be installed in a
dry, cool, dust-free environment.
Please leave at least 300mm
clearance at the left and right hand
sides (Black heatsink fins),
300mm above the inverter and
approx. 200mm at the rear as this
will aid the natural cooling of the
inverter. The air vents on the
underside of the SA41 also need to
be kept clear of obstructions.

(E.L.C.B.)
We suggest that you house your inverter along with other power generating equipment in a remotely
sited purpose built area. Also make sure that the exhaust from your generator or other sources of heat or
fumes are kept well away from the SA41. SEIAA (Solar Energy Industries Association Of Australia)
installation guidelines must be followed.
You must have a suitable 48V DC battery bank which is maintained and operated to the battery
manufacturer’s recommendation. To ensure operation to SA41 specification, the battery bank should
have a minimum capacity of 500 ampere hours, at the 100 hour discharge rate (ask your supplier if in
doubt). Smaller capacity batteries can be used but may result in degraded performance of the SA41
under heavy surge conditions.
CONNECTION OF AC AND DC WIRING
IMPORTANT: Before making any wiring connections, check that the circuit breaker located on the
front panel is in the OFF position, i.e. LEVER DOWN.
Your electrician should firstly connect the AC wiring via the three terminal rear junction box. Carefully
observe the correct connections. Please refer to the rear panel view of the SA41 on the following page.
BROWN ACTIVE (red dot, top connector)
GREEN/YELLOW EARTH (E, centre connector)
BLUE NEUTRAL (Bottom connector)
The lid of the junction box has knockouts to allow conduit entry. Make sure the connections are tight
and safe. Re-fit junction box cover.
NOTE:
ALL AC WIRING MUST BE CARRIED OUT BY A LICENSED ELECTRICIAN
AND MUST CONFORM TO AS 3000 WIRING REGULATIONS,
OR RELEVANT STANDARDS.
Verify that the circuit breaker on the front panel is in the OFF position, LEVER DOWN.
3
Now connect the battery cables:
RED = BATTERY POSITIVE (+)
BLACK = BATTERY NEGATIVE (-)
These connections should be tight. If using nuts, bolts and washers, they should be stainless steel. At
this point re-check the connections before proceeding any further.
NOTE:
IF THE SA41 EMITS A PULSING BUZZER SOUND, THE BATTERY LEADS HAVE BEEN
CONNECTED IN REVERSE. IMMEDIATELY DISCONNECT THE LEADS AND RECONNECT
WITH THE CORRECT POLARITY. DO NOT UNDER ANY CIRCUMSTANCES TURN ON THE
BREAKER WHEN THE BUZZER IS PULSING AS PERMANENT DAMAGE TO THE SA41
WILL RESULT.
If all is well, turn the breaker ON, i.e. switch lever UP. If after two (2) attempts the circuit breaker does
not turn on, then check that the battery voltage is between 40 and 68V DC. If the breaker still won't
switch on, refer to the FAULT FINDING section of this manual.

OPERATION
To gain more understanding of these operational notes, it is suggested that they be read in conjunction
with hands on access to an inverter with DC power applied.
When you first apply power to the SA41 with default factory settings, the SA41 should be in
STANDBY mode. There may be a quiet pulsing sound and the red neons on the power point will flash
if turned on. The SA41 is now ready for use with no further adjustments necessary, using the factory
settings.
If the display shows TIME, the default settings have been changed, and the day and time will need to
be set before the display will return to STATUS.
ENERGY MANAGEMENT
The SA41 incorporates ENERGY MANAGEMENT, which allows you to monitor and control your
energy system by displaying information on the Liquid Crystal Display. Settings can be adjusted via
the front panel keys.
STATUS
Status : STANDBY
Inverter : OFF
The first screen will display the Status of the SA41. There are three status conditions: STANDBY,
CONT (continuous) and RESET, which are explained in more detail below.
When this screen is displayed, the Status can be changed by pressing the UP or DOWN keys. Each time
the UP key is pressed, the status will change from STANDBY to CONT then RESET and back to
STANDBY whereas the DOWN key will change the Status in the reverse order.
The second line indicates whether the inverter is ON or OFF, i.e. if there is 240V available or not.
During pulsing, OFF is displayed on the second line, reverting to ON when a load is connected and the
inverter starts.
Status : CONT
Inverter : ON
Status : RESET
Inverter : OFF
The STANDBY mode means that the SA41 is producing pulses of power while waiting for an
appliance to be switched on. This is frequently called the “demand start” because as soon as the
appliance is operated, the SA41 will turn on and remain on until the appliance is switched off. After a
10 second delay, the SA41 will return to STANDBY mode, awaiting another load.
This feature is extremely important as it conserves valuable battery power when no appliances are on.
CONT mode (continuous) means the inverter will be on at all times regardless of the load. This
situation is useful if you have small loads such as VCRs or digital clocks that require 24 hour power, or
if loads are too small to be sensed in the STANDBY mode. The only disadvantage is that when no
appliances are operating, the SA41 will be drawing more power than it would in STANDBY mode.
RESET mode electronically shuts down the inverter. When placed in this mode, any overload or
shutdown conditions are also reset.
5
READINGS
The SA41 ENERGY MANAGEMENT has six "Readings" displays to give you vital information
about your inverter and your batteries. By pressing the 'NEXT DISPLAY' key on the front panel, the
screen information rotates through displays of inverter Status, Time, AC Volts, AC Amps and Battery
Volts. When the optional current shunt (SA-S200) is installed, four additional readings are available;
these being Nett DC Current, Peak Charge Current, Nett Daily Amp Hours and Battery percentage
Charge.
TIME
Mon : 15:06
- - - Readings - - -
AC VOLTS
AC Volts : 240V
- - - Readings - - -
AC AMPS
AC Amps : 2.5A
- - - Readings - - -
BATTERY VOLTS
Displays the Current Time (as a 24Hr clock) and day. This time is set as
described in "Settings" (see Page 8).
This screen gives an approximate indication of the AC voltage produced by
the inverter. The AC volts would normally read between 230V and 245V
except under high load or low battery conditions.
The AC current reading shows the total current drawn from the AC output
by the appliances connected to the inverter.
Batt Volts : 49.2V
- - - Readings - - -
Displays the DC Battery volts. This provides you with an indication of the
condition of your battery bank.
WHERE THE OPTIONAL 200 AMP CURRENT SHUNT IS INSTALLED:
DC CURRENT
Amps : 23.6A OUT
- - - Battery - - -
PEAK AMPS
Pk Amps : 45.6 IN
- - - Battery - - -
This reading gives a Nett current; i.e., either charging the battery (IN) or
being taken out of the battery (OUT). The range for this reading is 0-100A
IN and 0-200A OUT continuous or 0-400A OUT intermittent.
This reading gives the peak Nett charging current into the batteries for the
present day (today). If no load has been present for the entire day, this will
indicate the peak combined charging current from your solar panels, wind
generator or other charging sources, thus allowing you to monitor their
operation. During the first day after the inverter is turned on at the circuit
breaker, this screen will display a meaningless figure.
6
NETT AMP HOURS TODAY
Net AH : 69 IN
- - - Today - - -
BATTERY CHARGE
Charge : 87%
- - - In Battery - - -
This reading gives a nett figure of Amp Hours since midnight last night. A
nett AH reading of IN indicates more Amp Hours have gone into the
battery than have been used. The opposite applies for a Net AH reading of
OUT.
1 Amp Hour = 1 amp for 1 hour, or 2 amps for ½ hour, etc.
This reading shows the amount of charge present in you battery bank at any
given time. i.e. 100% means a fully charged battery.
MINIMUM CHARGE
With the optional current shunt (SA-S200) installed, the minimum charge in your batteries today, this
week or for a number of weeks or days can be logged (Minimum daily discharge). Minimum charge
readings are accessed by pressing the UP and DOWN keys together for 1 second.
These vital readings give you the information you need to maximise your battery life. This is done by
managing your loads to maximise this figure, e.g. using heavier loads later in the day or at other times
when the battery charge is high.
MINIMUM CHARGE TODAY
MIN CHARGE : 76%
- - - In Batt Today - - -
MINIMUM CHARGE THIS WEEK
MIN CHARGE : 76%
- - - In Batt This Wk - - -
MINIMUM CHARGE WEEKLY LOG
Weeks ago : 1
Min Charge : 76%
The minimum charge in the battery since midnight last.
The minimum charge in the battery since midnight last Saturday.
This displays a log of the minimum weekly charge in the battery for up to
52 weeks. The logged weeks may be stepped through by pressing the UP or
DOWN key. The weeks that have not logged AH as yet will display 255%.
MINIMUM CHARGE DAILY LOG
Days ago : 1
Min Charge : 76%
This displays a log of minimum daily charge in the battery for up to 30
days. The logged days may be stepped though by pressing the UP or
DOWN key. The days that have not logged AH as yet will display 255%.

SETTINGS
There are a number of settings within the SA41 that can be changed via the front panel push keys (push
buttons). These allow you to tailor the SA41 inverter and ENERGY MANAGEMENT sections to suit
your system requirements.
Settings are accessed by holding down the NEXT DISPLAY key for at least 1 second whilst in any
"Readings" display. The value of the parameter displayed can be modified by pressing the UP or
DOWN keys.
Pressing the NEXT DISPLAY key will take you to the next parameter to be set. Pressing the NEXT
DISPLAY key after the last parameter is displayed will take you back to the "Readings" displays.
Please note: If DC power is disconnected from the inverter, the "Settings" which have been entered
will be saved and held in permanent memory. However these settings are not saved until the display is
returned to "Readings".
CONTROLLER OUTPUTS
The SA41 ENERGY MANAGEMENT has 2 control outputs, as mentioned on page 25, each of
which can be activated with time, inverter cutout and/or low ampere-hours. The six settings are
displayed as OFF, ON, TIME, INV CO, LO A/H and CO+LAH respectively
For simplicity, the displays shown are for control output 1 only. Control output 2 settings are identical
to control output 1. Pressing the UP or DOWN keys will change the setting.
On with : OFF
[Set Control 1]
On with : ON
[Set Control 1]

[Set Control 1]
On with : CO+LAH
[Set Control 1]
Note that the controller can only be set to LO A/H and CO+LAH if the optional external current shunt
kit (SA-S200) is used. Each controller output is capable of switching an external relay or contactor
which can be used to switch AC or DC loads.
If the controller is set to INV CO, LO A/H or CO+LAH and the condition still exists after the
"Duration" time, the output will stay on until the condition ends. Also with these settings a "Lockout"
option can be set ON or OFF. (See lockout below and on page 11)
(Low Amp-Hours) If the charge in the batteries falls below the level set in
the "Minimum Charge" setting (see page 13), then the control output will
come on, for the time set in "Duration", below.
(Cutout or Low Amp-Hours) This setting combines the previous two, bring
the output on with low amp hours, or with the inverter cutting out.
The output will stay on for the time set in "Duration", below.
