Great off-grid pure sine-wave inverter-chargers
Selectronic sine wave power inverters offer a complete range, giving you quiet, clean, efficient sources of remote power anywhere, at any time.
Selectronic SP PRO inverters are suitable for single phase, split phase and three phase Off Grid power systems for households, homesteads, commercial properties, construction sites, or in fact any site where you want better-than-mains quality power.
Selectronic SP Pro inverters are proudly Australian designed and built.
Interactive Inverter Chargers
Selectronic SP PRO Interactive Inverter Chargers use the battery bank to store excess energy from renewable sources (normally PV solar) for periods when power demand is low. When the power demand is too high for the inverter alone, or when the battery bank requires recharging, the inverter automatically starts a generator.
This unique range of inverter chargers allow sharing of the load between the inverter and the generator set to maximise power output capacity..
The SP PRO Series inverters is the latest development of Interactive Inverter Chargers by Selectronic.
By managing all the functions of an off-grid power system, the SP PRO inverter ensures the efficient supply of mains quality power to the customer’s load as required. These functions include managing battery bank charge state, maximising renewable energy sources and operating the generator as required.
Sizes range from 3 kW to 20 kW for a single phase system, 6 kW to 40 kW for a split phase system and 9 kW to 60 kW for the SP PRO in a three phase configuration. Simple settings in the included SP LINK software enable the SP PRO to be configured for use in leisure and remote power systems. The SP PRO is suitable for residential, commercial and industrial applications.
Designed from the ground up, the SP PRO features advanced thermal power management and super high speed digital signal processing; setting new standards for reliability, features, surge capability and power density.

Hybrid on-grid inverter-chargers with reliable battery backup.
This versatile inverter offers the ability to store energy in, and use energy from, a battery storage system, even when connected to the grid. Whether you wish to install protection for brown-outs or improve the quality of grid power supplied, the SP PRO provides the solution.
Security of Backup Power
During a brown out, the SP PRO solar hybrid system will continue to supply the house load directly from the solar panels, whilst storing any excess solar energy in the battery, to be used later. This gives the user continuous power and peace of mind. Any shortfall of power needed can be automatically supplied from the battery, whether or not the solar panels are generating.
The SP Pro is compatible with most forms of renewable energy and can use solar, micro hydro and wind to charge the batteries, and then supply into virtually any grid or mini-grid system.
Maximise power usage times
The SP PRO Solar Hybrid function allows the user to use virtually all of their renewable energy, and minimises their dependence on power supplied by the grid. Grid export and grid import can be regulated by time of the day, and by power limits, as required. This is a very flexible machine, and can be easily programmed for maximum benefit.
Security of Backup Power
During a brown out, the SP PRO solar hybrid system will supply the load from the solar panels whilst storing any excess energy in the battery, to be used as needed. This gives the user continuous power and peace of mind.
Managed AC Coupling
By combining the SP PRO inverter with a KACO Powador inverter in a Selectronic / KAKO AC couplingconfiguration, a fully integrated and managed Solar Hybrid system is possible. With system sizes from 3kW to 20kW single phase (with up to 30kW of PV solar), 6kW to 40kW split phase (with up to 60kW of PV solar) and 9kW to 60kW three phase (with up to 90kW of PV solar) the SP PRO Series of inverters is suitable for use in On Grid power systems for residential, commercial and industrial applications.
By connecting up to 5 KACO Grid Tie inverters to the AC Load side (output) of any single phase SP PRO system, it is now possible to utilise efficient high voltage PV arrays that are located remotely from the battery bank. This allows you to continue to use a wide choice of PV installers and common components; no need to be concerned about cable loss in long, expensive low voltage cable runs.
By creating an AC Bus, an AC Coupled system will allow PV energy to be efficiently used directly by the load with excess PV energy going back through the bi-directional SP PRO to charge batteries or export to the grid.
PV energy will continue to be utilised at all times, regardless of generator or grid availability. This 5-stage battery charging system used in the SP PRO has proven unmatched in control and stability. This has now been extended into PV based AC Coupled systems. The SP PRO/KACO RS485 link provides the same precise control over the AC Coupled PV. Regardless of the charging source, your batteries will enjoy maximum life with SP PRO charging.
Grid back-up support for brown-outs (up to 100kw with solar)
Latest model SP Pro GO models with zero grid export, mean that solar can be installed anywhere, safely, without power company permission.
Boost performance and reliability with one smart inverter
When you need increased capacity, reliability or functionality of your electricity grid,
the Selectronic SP PRO series of battery based inverter-chargers will have the right answer for you.
Boost customer supply capacity
In “fringe of grid” situations, a property may require more power than the grid can supply, but upgrading lines may not be practical or economical. In this situation an SP PRO is placed at the customer’s premises with a battery bank.
When the supply limit is exceeded additional energy will come from the SP PRO via the batteries, and when load is decreased grid energy will be used to charge batteries again if required. Renewable Energy sources can provide power to recharge the batteries, feed this into the grid or to be used onsite.
Boosting Grid supply capacity
Using an external controller, the SP PRO can be commanded to feed stored battery energy at any power factor into the grid, augmenting supply capacity. Commanding the SP PRO is a specialist feature made available under a signed agreement.
Peak lopping
An SP PRO strategically placed within a network can be programmed or commanded to cap the peak demand to a known limit, preventing line overload and the associated costs due to loss of supply. Use of this feature allows a fast and cost effective means of increasing network capacity, either temporarily or permanently. Consequently line utilisation is both predictable and controllable.
Load shedding
It is often required that a branch line will need to be isolated for safety, maintenance or load shed purposes.
Properties or sub divisions with SP PRO support will enjoy an uninterrupted power supply, thus demanding a lower priority response. This gives greater flexibility and efficiency to line restoration crews.
Quality of supply
Exposure to liability claims is a major concern in today’s business world. Quality of supply can be maintained regardless of line irregularities with the rapid detection and islanding capabilities of the SP PRO.
Smart Grid
Future developments will see the SP PRO integrate within the AMI infrastructure via industry standard protocols. With so much flexibility within the SP PRO and incorporated into a Smart Grid, the possibilities of control and integration into smart storage systems are numerous.
Adding Renewable or Alternate Energy sources A line supported by an SP PRO can easily be further augmented with the inclusion of any type of Renewable or alternate energy source. Solar panels can be integrated via the DC or AC coupling method.
Balance of system
Selectronic can take the worry out of system integration by providing you with all of the components required for a system. Most batteries are compatible with an SP PRO and our pre sales design service will ensure your system achieves all of its objectives.

Regardless of the charging source, your batteries will enjoy maximum life with SP PRO charging.
The grid inverters can be considered as an AC MPPT charger. A maximum of 5 inverters can be controlled by any SP PRO, but the total AC Output of the combined grid inverters must not exceed twice the continuous power rating of the chosen SP PRO or the SP PRO surge rating, whichever is smallest. Presently, the ABB Uno series and the Fronius Primo series supplied by Selectronic are suitable for AC Coupling. They range from 3kW to 60kW AC output.
Site consumption and generation data continue to be logged by the SP PRO including the AC Coupled solar production.
