Not to mention that the whole battery idea they have is a bunch of crap, inefficient and expensive, big waste of time unless FRAUD is a normal business practice.

A Trojan L16 deep cycle battery has a 370AH rating at 6 volts, or 2,200 watt-hours. Each. You can draw them down 50% repeatedly without problem. Four of them in series will produce about 4 kilowatt-hours of reliable power (their nominal rating is more than twice that, or roughly comparable to Tesla’s “power wall”) and the output of four in series is 24V which is compatible with commodity inverter/charger equipment unlike Tesla’s “Powerwall” which is not. The Trojans also cost about $400 each, which means four of them cost $1,600 or less than half the price, at retail, what Tesla wants as a wholesale price for their “powerwall” and a 3kw inverter/charger to go with the Trojans can be had for about another $1,000 as that is commodity equipment unlike the Tesla gear.
