This 5.28kW system is the largest system that can be installed and still take advantage of the very generous Queensland Government feed-in tariff. So if you’re a large power user or just want to make the most out of the current feed-in tariff, a system around this size is the way to go. The Sunny Boy 5000TL inverter is the perfect choice as its flexibility is unbeatable. If you have limited roof space and you need to split the panel array over two roofs with different orientations this is the inverter for you. In the past if we had to split the panel array over two roofs at different orientations we would have recommended using two separate inverters, however with the introduction of SMA SB4000TL and the SMA SB5000TL into the Australian market using two inverters is a thing of the past as these inverters have dual array inputs.
