1
AC SOURCE *
When illuminated this LED shows the presence of AC input
voltage from either a motor generator or the mains grid,
whichever is applicable. This LED is powered directly from
the incoming AC Source.
2
AC TRANSFER *
Illuminated when an external AC source is connected to
AC loads. If the AC source LED is illuminated but not the
transfer LED it would generally indicate that the input is out
of tolerance – that is that either the voltage or the frequency
of the source is unacceptable. If the source is a motor
generator check if it needs servicing; if the mains grid check
with your supplier for a problem or that the tolerances have
not been set too tight.
3
AC LOAD *
When illuminated this LED shows the presence of AC voltage
ready to supply loads. If, in normal running conditions, it is
not illuminated it indicates there is a fault within the system.
* These LEDs can operate even if your SP PRO
is not switched on. An external power source
can activate these LEDs.
4
GENERATOR (MULTI FUNCTION LED)
Flashing Green - generator is in the process of starting
Steady Green - generator has started
Flashing Yellow - generator is not available for auto start
Flashing Red - there is a generator fault
5
GENERATOR START/STOP BUTTON
A brief press of this button (<1 second) will start or stop the
generator. Two long presses (>2 seconds) will request an
equalizing charge on the batteries after full battery charge.
6
ExPORT
This LED indicates, in a grid connected system, that the
SP PRO is exporting power to the grid: On, renewable
feeding grid and AC Load; Flashing, feeding AC Load.
7
OUTPUT MODE (MULTI FUNCTION LED)
Off
Inverter is monitoring but providing
no output.
Steady Green
The inverter is performing normally.
Slow Flashing Green SP PRO Econo mode is enabled and
is
sensing load conditions.
Fast Flashing Green SP PRO is preparing to start.
Steady Red
Indicates that a Unit Fault has been
detected and not output is
possible.
8
OUTPUT MODE BUTTON
LONG PRESS
(>1 second) - turns the SP PRO on, another
long press turns SP PRO off. LED is steady green.
SHORT PRESS
(<1 second) - activates Econo mode. LED is
flashing green.

CHARGING SOURCE
If AC LED is on, it indicates the SP PRO using an external
AC source such as a generator or shore power to charge the
batteries.
If RENEWABLE LED is on, it indicates the SP PRO has
detected a charge current of greater than 0.4 Amp on either
external shunt. Shunts by default are disabled and must be
enabled using SP LINK for detection of current.
Both LEDs may on together.
11
FUEL GAUGE
This series of LEDs will represent the voltage of your battery.
All LEDs on indicate the battery is at Float voltage. If just
the bottom LED is on, battery voltage is approaching the
Shutdown voltage.
If your SP PRO has State of Charge enabled, the series
of LEDs will represent the percentage of usable charge
remaining in the batteries. Usable charge is defined from
100% SoC down to the Shutdown SoC parameter.
In voltage or state of charge mode, the second LED from the
bottom will glow yellow to indicate you are approaching a
shutdown situation. When the bottom LED is flashing RED,
the SP PRO is about to shutdown
When all LEDs are flashing RED, inverter is in Low DC
Shutdown Override or “Just Go” mode. The “Just Go”
feature enables the inverter to be forced to work even when
the battery voltage is too low in emergency situations, this
will only apply until the battery voltage will no longer keep
the inverter running. We remind you, using this emergency
feature may damage your batteries or connected
equipment.
12
ALARM SILENCE BUTTON
The Alarm Silence button cancels any audible alarm. This
does not remove the alarm, just the audible component.
13
OVERTEMP
Yellow -
SP PRO is approaching an over temperature
situation
Red -
SP PRO has shutdown due to an over
temperature situation
14
SHUTDOWN
Yellow -
SP PRO is approaching a shutdown situation
Red -
SP PRO has shutdown
15
SERVICE REQUIRED
There are a number of preventative steps that can avoid a
premature fault situation within the inverter – such as the fan
filter requiring cleaning. When this LED illuminates consult
the “Data View” section of SP LINK to determine the reason
for the alert.
The Charging Mode panel, comprising LEDs
16, 17, 18
&
19
indicate the stage of the charging process that is
presently being performed, or the stage that will be started
at the next starting of the generator or the connection of the
mains grid. The SP PRO calculates the input from renewable
sources to help arrive at the appropriate charge stage.
