Thank you for purchasing a Selectronic SP PRO series 2i sine wave Interactive Inverter Charger
optimised for either grid connected power systems (also called Solar Hybrid Power Systems) or
O󰀨 Grid systems (no grid power available).
Selectronic has an accredited Quality Assurance system covering both their manufacturing and
design operations with over 25 years experience designing power conversion equipment for both
domestic and industrial purposes.
As a result Selectronic has had many opportunities to listen to both integrators and system
owners to determine their real needs.
We have learnt from our customers that:
• Modern solar energy systems need to do more than provide power when the sun shines,
• A simple or complex system should be a matter of choice. The inverter should be able to
perform with ease of conguration yet be capable of integrating into the most advanced
energy system.
• Battery longevity is paramount. A combination of battery protection and the best charging
methods are essential.
• Monitoring / conguration software should be user friendly with intuitive “at a glance”
menu clarity.
The SP PRO has been designed with these, and many other criteria in mind.
In addition to power conversion the SP PRO controls the operation of the entire energy system
ensuring all sources of renewable energy are fully utilised whilst reducing the use of either grid
power or generator power. The SP PRO is a complete Energy System.
With the easy to use SP LINK Site Conguration Wizard the SP PRO can easily be “hung on
the wall” and congured to suit most renewable energy installations. Further functionality is also
possible when using the Advanced Conguration settings to tailor the SP PRO to suit a more
complex system requirements.
We are always interested in feedback about this document or the SP PRO. Please do not
hesitate to contact us via our web site www.selectronic.com.au .
When installed and maintained correctly the SP PRO will give many years of trouble free
operation.

INTRODUCTION | Product Overview
8 | Doc #OI0003 Part #004122 Rev29 2020
The SP PRO Sine wave Interactive Inverter Charger is designed specically for either Solar Hybrid (grid
support / grid feed) or O󰀨 Grid (no grid available) operation.
With Powerchain capability, the SP PRO can be congured as either a single phase power system with up to
four SP PROs or a three phase conguration with up to twelve SP PROs (four per phase). A Split phase with
eight SP PROs is also possible. With all SP PROs in a Powerchain system operating in perfect harmony, the
power system is congured, controlled and monitored as one.
As a battery based inverter, charger and system controller all in the one product. Each SP PRO has a
congurable export power limit suitable for many export limited Solar Hybrid applications.
With its in built generator controller the SP PRO is also the ideal choice for all O󰀨 Grid installations or Solar
Hybrid systems with generator back up.
The SP PRO is compatible with virtually any DC renewable charging source (such as a DC solar controller).
Also any AC renewable source (such as a grid tie inverter) is compatible with the SP PRO in a Solar Hybrid
system without limited export power.
For O󰀨 Grid Systems or Solar Hybrid systems requiring export limiting the Selectronic Managed AC Coupling
must be used. Its advanced features include the precise control of either a Selectronic Certied (SCERT) grid
tie inverter or the Selectronic SelectSun grid tie inverter, making it ideal for either an O󰀨 Grid charging system
or maintain a Solar Hybrid export limit.
Solar Hybrid Support and Grid Feed Systems
Product Overview
Chapter One

INTRODUCTION | Product Overview
Doc #OI0003 Part #004122 Rev29 2020 | 9
In Solar Hybrid, the renewable energy can be directed to power the AC load, recharge the battery bank and/
or export to the grid. The direction and priority of the energy ow can be varied depending on the time of day,
battery SoC or load demands allowing the maximum use of the renewable energy (such as PV solar) and
stored battery energy to supply loads to take advantage of variable electricity tari󰀨s. A Solar Hybrid system
will allow the user to only use grid electricity when they choose.
By using the optional “Grid fail - Gen backup” module the SP PRO can be congured to automatically start
and stop a generator during a prolonged power outage. When the generator is running, the SP PRO will use
the generator to power the site load plus use any additional generator capacity to charge the batteries.
O󰀨 Grid Stand Alone Power Systems (SPS)
The SP PRO is the heart of the power system. It quietly provides AC power from the battery bank and
renewable sources. By using SP LINK the SP PRO can be congured to monitor battery state of charge
and load conditions to automatically start and stop the generator as required to charge the batteries and
supply loads heavier than the SP PRO can e󰀩ciently handle. These features, when correctly congured, will
increase the battery life and reduce generator running costs.
When the generator is running, the SP PRO will use the generator to power the site load; plus use any
additional generator capacity to charge the batteries. When the site loads are greater than the generators
output, the SP PRO will add its power to the generator. When the site loads are reduced, the SP PRO will
return to battery charging. The above operation happens automatically, whilst always maintaining “no break”
power to the site.
An SP PRO managed AC Coupled system is suitable for O󰀨 Grid systems due to the superior battery
charging functions that are achieved by a sophisticated system control and monitoring communications link
between the SP PRO and compatible grid inverters.

INSTALLATION | Precautions and Safety
10 | Doc #OI0003 Part #004122 Rev29 2020
Warning: If this equipment is used in a manner not specied by the manufacturer as contained
in this manual and other operational documents and Instructions, then the protection provided
by the equipment may be compromised.
Who should install this unit
The SP PRO is designed for easy installation and can be installed by any suitably qualied person.
The voltages produced within a power system are hazardous. Even though the SP PRO may derive its input
from a battery, the extremely high current capability of a battery bank is hazardous. Additionally the high
voltage battery banks (120V) used in the SPMC1201, SPLC1200 and SPLC1202 are hazardous and the
output and input AC voltage in all the SP PRO models is just a hazardous as grid electricity.
All AC connections and hazardous DC connections to the SP PRO must be carried out by a qualied
Electrical contractor or similar, failure to do so will contravene legal requirements.
All DC wiring must be carried out by a person experienced with DC electrical circuits and must understand
high current low voltage circuits. To ensure an e󰀩cient system installation, cable sizing and voltage drop
must be understood and the recommendations within this manual followed.
Selectronic Australia shall have no obligation as to any equipment which has been improperly installed,
stored, or handled, or which has not been operated or maintained according to this manual, nor for any
operating mistakes and consequences arising from them.
This product is not to be used for Life Support equipment
Protective Earth connection
It is critical that all protective earth connections made within the SP PRO use the
protective earth terminal. This is the earth terminal that is on the right hand side of
the AC terminals and marked with a earth symbol enclosed in a circle.
Multiple Hazardous Energy Sources
Hazardous voltages and energy are generated by the SP PRO, are fed into the
SP PRO by external wiring from multiple sources and are stored in capacitors after
the SP PRO is switched o󰀨 and disconnected from external wiring.
Precautions and Safety
Chapter Two

INSTALLATION | Precautions and Safety
Doc #OI0003 Part #004122 Rev29 2020 | 11
Preparation
Whilst every e󰀨ort has been made to pack the SP PRO in a way that will provide adequate protection,
damage in transit can occur. Please carefully check the packaging and the SP PRO for signs of damage and
for all components mentioned in the “Included in the Package” section of this manual.
Please report any damage or missing parts to Selectronic or a Selectronic Authorised Distributor.
Please retain the original packaging for the safest and most e󰀨ective method of repackaging if required.
Installation
The SP PRO requires adequate ventilation, away from hot equipment. Do not obstruct the airow
passage of the SP PRO case (top and bottom). Ensure when installed in an enclosed space that
there is adequate ventilation.
The SP PRO must be located in a place away from electrolyte and corrosive aerosols.
The SP PRO contains arcing contacts so must not be located near explosive gas mixtures such
as hydrogen from batteries or diesel fumes.
Maintenance
Ensure that all energy sources are isolated before working on connected wiring. A backup
generator may start or power may be restored by the SP PRO at any time. Never work on
equipment or investigate a problem without following appropriate safety isolation procedures.
Inverter may start automatically
The SP PRO automatically starts and/or restarts and may restore power at any time. If a fault
or overload is detected the SP PRO will shutdown and may automatically attempt to restart at
varying intervals of up to several hours.
Backup Generator may start automatically
The SP PRO automatically starts and/or restarts a backup generator (when a Grid Fail - Gen
Backup option is installed). If a fault or overload caused the SP PRO to shutdown then it will
automatically attempt to start and restart the backup generator.
Battery
Batteries are very dangerous. Please read the safety information provided by the battery
supplier.
• Battery acid is dangerous.
• Batteries can emit hydrogen gas, which is explosive.
• Batteries connected in series can produce hazardous voltages.
• Batteries are capable of sourcing extremely high output currents. Short circuit or high overload currents
can be extremely hazardous and cause high current arcs, burns and explosions.
• Disconnecting a DC power connection (even on one battery cell) can cause dangerous high-energy DC
arcs, which can cause serious burns and eject hot particles, and can be di󰀩cult to extinguish.
• Disconnecting a DC power connection (even on one battery cell) can cause renewable sources to
produce large voltages (much larger than the battery voltage) on battery terminals and DC wiring. Such
voltages can be lethal. They can also damage the SP PRO. Only suitably trained and qualied personnel
should disconnect any DC power connection, including battery cell connections, and only with suitable
procedures and safety precautions.
• System battery voltages of 60 V or greater are to be treated as a hazardous voltage.

INSTALLATION | General Requirements
12 | Doc #OI0003 Part #004122 Rev29 2020
Installation-General Requirements
Chapter Three
The SP PRO must only be installed by suitably qualied personnel.
Many procedures covered in the INSTALLATION sections of this manual have
inherent risks. Whilst the SP PRO is designed to be safe, including safety
features never before found in an inverter (such as Earth / Neutral bond
monitoring), the voltages connected to or generated within the SP PRO are
hazardous and potentially fatal.
It is the responsibility of the installer to ensure the installation and all the
wiring is carried out according to all safety standards that are applicable to the
installation. The wiring diagrams and installation instructions are given as a
guide only and compliance to appropriate standards is the responsibility of the
installer.
The following section provides general installation instructions for the SP PRO . For information
on specic congurations please refer to the “Installation-Specic Applications” Section in this
manual and the relevant installation guide supplied with any required installation options.

Environmental Considerations
ENVIRONMENTAL CATEGORY
The SP PRO is design with an Environmental Category (as dened by IEC 62109.1) for “Indoor,
unconditioned. The SP PRO must be protected by a building or enclosure from direct rain, sun, wind-blown
dust, fungus and radiation to the night sky.
The SP PRO must be installed in a dry environment.
POLLUTION DEGREE 2
The SP PRO is designed to operate in a Pollution Degree 2 environment. Normally only non-conductive
pollution occurs with occasional temporary conduction due to condensation expected.
TEMPERATURE
The SP PRO is designed for an ambient operating temperature between -20°C and 60°C, with a storage
temperature range between –20°C and 70°C.
AIR FLOW
For best performance ensure nothing impedes ambient air from being drawn in the bottom of the unit and
that hot exit air is vented away and doesn’t recirculate into the unit. Particular attention must be paid when
installed inside a cabinet or enclosure.
CLEARANCE FROM OTHER EQUIPMENT
A recommended clearance distance of 150 mm around all sides, top and bottom. Particular care must be
taken when mounting near other heat producing equipment.
HUMIDITY TOLERANCE
The SP PRO is designed to operate in a humidity range of 0 – 99% non condensing.
INGRESS OF PARTICLES
The SP PRO has been designed to meet IP rating 43 (Protected against solid objects larger than 1.0 mm /
protected against water falling as a spray at up to 60 degrees from the vertical).
E󰀨ects of altitude on the SP PRO
Altitude
(m)
Derating Factor
@ 40°C
0, sea level 1.00
1000 0.95
1500 0.90
2000 0.85
The power rating of the SP PRO should be compensated for the e󰀨ects of altitude by applying the
appropriate derating factor. For example, at 2000 m above sea level, 6 kW x 0.85 = 5.1 kW. The altitude
compensated rating is still at 40°C.

INSTALLATION | General Requirements
14 | Doc #OI0003 Part #004122 Rev29 2020
Preparation
The selection of a suitable site and good preparation is essential in gaining optimum performance from the
SP PRO.
SP PRO Inverter performance is dependent upon the environmental operating conditions, in particular ambient
temperature and ventilation. In addition safety aspects must be considered, such as:
• Restrict access to authorised personnel only.
• Consideration of maintenance of ambient temperatures to ensure performance within product
specication.
• Positioned away from heat producing devices such as generators.
• Adequate ventilation, adhering to the minimum clearances required for adequate heat dissipation.
Minimum 150 mm clearance from top, bottom and sides.
• In a covered location away from direct rain. The SP PRO has an environmental rating of IP43 which
makes it unsuitable for water spray that is greater than 60 deg from the vertical or greater than 0.7 litres
per minute.
• In a location shaded from direct sunlight.
• Away from any explosive gas.
• Rodent proof.
• In a clean environment away from dust, iron lings, workshop pollutants and other small particles.
• Enough room to remove the cover.
• The provision of infrastructure for monitoring - example data cables
The SP PRO should be installed in a separate area to the battery system (where used). The battery bank
can emit explosive gas (hydrogen) and this must be vented outside and away from the SP PRO. The battery
system should not be accessible by the user.
When batteries are used in the system it is recommended that the installation be in lockable area with a separating
partition or enclosure for the battery bank.
