Since we have drifted off the “emergency” use question, let me say that I don’t believe we should be using car batteries for solar storage, in fact I feel we should not be installing batteries in homes at all. What is needed is for consumers and utilities to come together to create fair power buy pack process. In this way the consumer is using the power company as their “battery” and making money while at it, and the power company is then able to reduce generation from none-renewable sources, which benefits everyone. Also, once in place, we can swiftly increase solar production since consumers would no longer have to spend money on panels AND batteries, switches, etc.
