Add Fronius GEN24 battery storage to exisiting grid connect system

Project involved adding battery storage to an exisiting grid connect system. Automatic backup power was required for lighting, general power circuits and an aircon unit in the house.

The original solar inverter was removed and replaced with a Fronius Primo GEN24 Plus hybrid inverter.
A BYD HVS 5.1kWhr battery system was also installed. This system is able to cope with extended grid outages as the solar will recharge the battery each day.

Selectronic stand alone system

Install of a stand alone solar power system.

4.4kW solar array. 16x Trina 275W modules.

5kW Selectronic battery inverter and 4kW ABB solar inverter.

13.8kWhr BYD Pro lithium battery.

5kW Grid connect system

Install of a 5kW grid connect system. System uses (18x) Trina 275W modules and a 5kW SMA inverter. Modules are mounted on a perfect north facing roof.
A Catch Power diverter is also installed. Any excess solar power that would normally be exported to the grid is now sent to the clients hot water system.

4kW grid connect system

Install of three 4kW grid connect systems. Each system uses (12x) Suntech 330W modules and (12x) Enphase IQ7+ micro inverters. Modules are mounted in an east / west configuration to produce maximum power at the same time that the clients use power.
The Enphase Envoy system controller gives provides full online power monitoring of both solar production and house hold consumption.

15kW Grid connect solar for Bakery


Installation of a 15kW grid connect solar power system to offset the power used by a local bakery.
At this time of year, Sept, the system is generating around 68kWhrs per sunny day.
SMA STP15000TL inverter and 55 Trina 275W modules.

15kW of PV for Holiday Cabins

Bunya Solar installed a total of 15kW of solar to power five cabins and two houses at a popular holiday destination in a National Park on the South Coast.

10kW of Trina 300W monocrystalline modules on the roof of one of the houses.



Two 5kW SMA Sunny Boy inverters convert the solar power to mains power for use around the site.

Stunning scenery from the site.

5kW of PV installed on the power shed and sent through another 5kW Sunny Boy inverter.

4kW stand alone power system


Installation of a stand alone solar power system.
5kW Selectronic SP Pro battery inverter
4kW of new and exisiting solar PV ac coupled via Fronius 4kW solar inverter.
10 kwhrs of BYD lithium battery storage.

Extra 4kW of PV for stand alone system.


New install of an extra 4kW of solar to an exisiting stand alone system. Solar is fed into a Fronius Primo 4 solar inverter and then AC coupled to a Selectronic SP Pro inverter for house power and battery charging.
16x Trina 270W modules.

1kW upgrade.

2kW grid connect solar system has an extra 1kW added. The simple AC architecture of the Enphase micro inverter system makes it very simple to add extra capacity to an exisiting system. Because of the comprehensive display that comes with the Enphase system the client was able to easily see that an extra 1kW of solar would cover their increased power needs.

3kW Grid install


3kW grid connected solar system installed near Broulee NSW.
11x Trina 275W modules.
11x Enphase S230 micro inverters and system controller.
Nice view for the install team.
