SMA Sunny IslandSMA Sunny Island

The Sunny Island is a comprehensive off-grid inverter/charger that benefits from 25 years of SMA experience. The Sunny Island inverter/chargers are German designed and manufactured and are perfect for use in AC coupled off-grid solar power Sunshine Coast systems.

The Sunny Island is extremely flexible and can be used to charge a wide variety of lead acid as well as lithium batteries such as the BYD.

In addition it can be programmed to auto-start a suitable generator if you need additional power or if your battery state of charge is too low. Another useful feature is the ability to load shed excess solar energy into non-essential items such as a garden irrigation system.

Wi-Fi monitoring is now standard on the Sunny Island 4.4, 6 and 8 models and providing the unit is connected to your home internet you can monitor the system from anywhere in the world via Sunny Portal.

This summary page from a system in Belli Park shows that 2.56kW of power is being provided by the solar panels, the house is using 1.89kW and the remaining 680watts is being used to charge the battery to 100%. The generator is not required at this stage.

5 Star Review - The Sun WorksSunWorks Solar on the Sunshine coast QLD, I installed a 5kW Fronius inverter and REC N-peak solar panels + a smart meter that allows me to see in real time on my mobile phone how much electricity is being generated by my panels, how much my house is using & how much is going back to the grid. I chose SunWorks because of the lack of bad reviews and the MANY good reviews online. Mike in the office was very knowledgeable and helpful & the installation guys were prompt & done very tidy work. They removed the old wiring from my previous solar system rather than utilizing it (no short cuts). I was impressed with their work from start to finish. My solar system is working great. I highly recommend SunWorks solar on the Sunshine coast QLD.
