Is anyone familiar with the new Kaco Ultraverter <http://kaco-newenergy.com/lounge/ultraverters/>? Its a microinverter with series-connected string architecture *on the AC side*! Pretty crazy. They say the lower voltages (nothing over 60V on the AC or DC side of each unit) reduces stress on components and allows for greater durability. Rapid Shutdown compliant for 2014 and 2017. 97.5% CEC efficiency. Pricing targeted between SolarEdge and Enphase, but willing to get very aggressive at rollout. As 100 year old German company, Kaco's 25-year warranty may offer a little more value compared with some other MLPE manufacturers. The biggest downside that I can see, assuming it works like its supposed to, is the 8-12 inverter-per-AC-string requirement. I'd be very interested to hear this esteemed group's thoughts on this unusual new microinverter product!

It's just that I prefer fusion to fission. And it just so happens that there's an enormous fusion reactor safely banked a few million miles from us. It delivers more than we could ever use in just about 8 minutes.
