Memphis,

Yes, you are loosing about 50% of your energy to use the grid as "your battery". But you will loose that and even more so with on site batteries (input/output efficiency). Then the cost of the batteries and the necessary equipment to provide for the seamless switching.

I know, I know - it is hard to accept a 50% loss to use the "grid battery". But it is cheap, existing and very little has to be done to use it as is.

Really take a look at your true cost to put in battery storage. My suggestion is that in five years, on site battery storage will be at a fraction of today's costs. Study, plan, but use what you can NOW.

Recall the phrase, never let the seduction of the perfect, distract you from the incredible utility of the good . . . . .
