What about the issue of efficiency in converting from AC to DC and then back to AC? Most modern appliances that we all own are AC. If we install a battery storage system at our homes, we have a number of choices which include buying some high-efficiency DC-oriented appliances, or an inverter to go from DC to AC, or whatever. In an extreme case, the best products may be DC, and then we have to think about converting AC-to-DC if we want them. Each of these conversion actions may have consequences in terms of lost energy, but I haven't yet figured out the losses. This has come up for me recently, so it's on my mind. ------------------------ Yahoo!
