rhodozelia not sure of your math there. 40kwh outputted at 5kw I make eight hours of use at max output? It's winter here so I'd say many households would empty it in less than two days easily. Equally in winter here 4kw of solar panels output about 4kwh's a day. So about two weeks to charge the battery and nothing else... Of course it's summer in Australia so much more solar output but you would be better putting it straight into your AC rather than storing it? Apart from running AC at night? $35000. That said if they can really get it to chug away for 30 years mainantance free unattended I can certainly see useful niches.
