I have the Grid Down Redoubt installed and I love it!
Grid Down has teamed up with Lion Energy (which I have owned their Sanctuary system for 2 years now and love) To make what I think is the best Energy Storage system even better! They are making it Lightning and EMP protected and easy for the DIYer to install.
