12 month in and our stand alone off the grid system is performing well. We have now been washing clothes and keeping our freezer running almost totally independent of the grid. Our system storage has been expanded to 500  Amp Hours, and a mains based trickle / boost  charger has been added for extended stromy dark weather. the total capacity of this  charger is only 7 amps, it can be switched in at 3, 4 or 7 amps as required. It is only rarely required. 

Now to the imporatant part, what have we really achieved. I will let the image to the right of  our latest quarterly bill speak for itself. When we started down the energy self sufficiency route we were purchasing around 19KW hours a day. This last quater which included a period of having numerous vistors and us running  2 bar fridges in addition to our normal load for 2 weeks we only purchased on average 4.6KW hours a day.

Based on our 2010 consumption this bill woul have been $708. So which bill would you prefer? Iit is not too late to join the green energy movement.
