I am sizing an on-grid with battery backup system that requires using a ground-mounted array that will be some distance from the house. I was favoring a Sunny Island with a 4 kW SunnyBoy with AC coupled to allow using a higher voltage from the array and the 4 kW Sunny Island shown in their product catalog which is perfect for this project, but all I can find is the Sunny Island 5048.
Is the smaller inverter not yet available? I will also have a backup generator with transfer switch feeding this system, so are there any issues with the Sunny Island operating from both a generator and the grid depending on which is available?
Thanks,
Jeff Yago
