Jay,
Coincidentially, while I was reading this today I got our first call from a
current customer wanting to investigate batteryless grid-tie. So I'm
requesting more info, please.
Array operating voltage? Cost? Web site for more info? I tried www.AEI.com,
but was unable to locate the product you describe.
Does Schott AP carry it?

Thank you.
Allan @+E
