Fronius 5.0.1 int 12amp Fronius 5.0.1 eu 16amp Fronius au are only 4.6kW 12amp.
We only sell the eu model. These days I can’t see why you’d go for poly panels when mono are not much more expensive ( about 200-300 more on 6.6kW system) and will last way longer. 3yrs ago maybe but not today, I only sell mono panels. We are a REC preferred installer. But again I’d go LG or Sunpower if you want really good panels. Half cell is more for shade but bird poo counts as shade. So look at your environment and what’s likely to cause issues. Sunpower Maxeon range just got STC approval, there bypass cell tech is rather impressive. And then again maybe look at Enphase micro’s.
I suppose it all comes down to dollars and cents, but what would you spend on a car these days and it will keep costing you, where as a quality solar system will last 30 years and save you a small fortune.
