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.

Close up of BYD HVS battery setup.

Backed up circuits in the clients house.
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.

Solar | SMA | Grid ConnectInstall 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.
