40kwh Lithium Off Grid Solar Storage "Power Cabinet" with Nissan Leaf and Chevy Volt Battery

Hey Guys, I have added 17.6kwh of Chevy Volt Lithium battery module to my 22kwh Nissan Leaf bank... Giving me a total of almost 40kwh of storage. I am planning to run my 3tons air conditioner unit through out summer with my 4kw Solar Array... harvesting every single drop of sunlight and store it whenever I possibly can. :) Nissan Leaf 12s7p 48v 462AH Chevy Volt 12s8p 48v 376ah
