You are missing something. The HD Wave is using a distributed multi-level stepped output to produce something much closer to a sine wave before filtering and smoothing. This increases efficiency and reduces the quantity of magnetics required since it is transferring most of the analog signal processing into the digital domain. It has been done before but only in inverters at much higher power ratings.
Also, your inverter weight comparisons don't look right. The smallest inverter I can find from either PowerOne or SMA weighs over 20 kg. Do you have a reference for a datasheet showing one at 8 kg?
Thanks Schueppert, an example is the SLA 9000TL is actually 35 KG, or 77 LBS. They seem to be a tad lighter, cheaper for sure but not that much lighter.
So, is there any chance we could see this in a solution that would support a powerpack?

Interesting and hopeful but that hardly solves an off grid installation problemThe SMA TL series have an off-grid feature they call "Secure power" where the system will deliver up to 15A to one 120V circuit when the grid goes down. No batteries needed.
