Matt I believe that Itek Energy will be shipping either June 1 or July 1 with Tigo ready modules. Please contact contact Karl Unterschuetz - ka...@itekenergy.com about sales. They are calling for a pre-order since they are transitioning from their old junctionbox to the Tigo. Tell him Bill Hoffer sent ya! Good solid made in USA module, I have worked on the product for them and extended testing to include PID and Bankability testing to confirm warranty. They are currently expanding into a new larger plant around 3rd quarter this year.
iTek Energy at 3886 Hammer Drive, Bellingham WA 98226 itekenergy.com Hope that helps!
