Selectronic SP Pro Series II

The SP PRO Series II is the perfect solution for Solar Hybrid (grid connect) applications and stand-alone power systems.

Add the versatility of energy storage to your Grid Connect solution using the SP PRO as a low voltage grid feeding inverter that puts you in control of your grid system.

Drawing on our inverter experience since 1981, the SP PRO contains features not found in other inverters. With highly accurate thermal power management and high speed digital signal processing, the SP PRO sets new standards for reliability, power density and flexibility.

Available in 3kw, 5kw & 7.5kw

Managed Inverters


Managed AC Coupling technology was developed by Selectronic in 2010. It allows the SP PRO to take control of the flow of

energy from the solar panels up to 0.1% steps to precisely control the solar power system while maintaining a stable 50 Hz

frequency. This cannot be achieved with a generic grid-tie inverter.

The Selectronic Certified grid-tie inverter can be considered as an AC MPPT. 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 multi-mode SP PRO

to charge batteries or export to the grid. Up to 5 Selectronic Certified inverters can be controlled by any single SP PRO.

We recommend Selectronic Certified grid-tie inverters for maximum system efficiency and flexibility in the following applications:

Off-grid AC coupling

Solar Hybrid AC coupling with Fixed Export Limits

Solar Hybrid AC coupling where twice the PV to SP PRO rating is required

For systems where 3 phase is required, we recommend the use of our SelectSun 20kW and 40kW products

Sungrow SG Crystal Premium Series

All SunGrow units offer outstanding quality and high efficiency ratings. With optimized components and striking, robust design, SunGrow inverters are constructed to withstand Australian conditions.

Available in 2kw, 2.5kw, 3kw & 5kw

Data Sheets - 3kw-5kw, 8kw




Sungrow Hybrid Inverter

In many countries, with the rising popularity of solar energy and its essential PV systems, the feed-in tariffs of PV power have dropped considerably.

For customers to store the PV generated electricity when it’s abundant, then utilise the stored power during the peak electricity tariff they must use a hybrid inverter.

The Sungrow hybrid inverter significantly increase the self-consumption of PV power. On the other hand, the utility grid will be more stable and reliable with less PV power feeding in. In addition, the SH5K hybrid inverter can also be utilised as a part of the "zero-export" system and power distribution network storage system.

ABB Trio

The compact, transformerless TRIOs are the latest products in the family for their performance, ease of use and installation, monitoring and control.

The TRIO-5.8/7.5/8.5 models enjoy high conversion efficiency across a wide range of input voltages, and the double MPPT gives maximum installation flexibility for an optimal energy production (TRIO-7.5/8.5 models). The new generation inverters can integrate power control, monitoring functionalities, and environmental sensor inputs, all without requiring external components. A compact expansion card gives access to the Ethernet datalogger, which allows parameters to be monitored both locally (with the integrated webserver) or remotely (via Aurora Vision), via a LAN connection.

Tweed Valley Solar Power Products - Battery Solutions


LG Chem RESU Solar Battery

The LG Chem is a Residential Energy Storage Unit (RESU) featuring a lithium ion battery with integrated battery management system.

The battery is able to tie in with a grid connect solar system to increase self-consumption and savings. An inverter is also required. The battery pack can also be utilised in an off-grid situation.

The LG Chem has a ten year warranty to prove the point, it can be cycled (discharged and re-charged) 6000 times. This is possibly the best value battery on the current market.

The battery pack is big enough to offset the evening energy use of an average household. Smaller households could cover evening and early morning electricity needs.

Available in 3.5kw, 6.5kw, 10kw & 13kw in 48 volt range
