750 watts may grow to 1000 watts. But at 750 watts, that would be 36 kWh battery minimum. 48 volt battery would be 750 Ah. That is a $6K battery or more and I am not sure you could even fit it in that size of a box.

So a site, with 450-750 watt consumption. 6 to 24 to 48 hour battery runtime, an option for a backup power source, solar, or turbine (small turbine). If the base requirement were a 48 volt plant, Secondary 24 volt (50w). Normally AC source (unless magic sauce made wind or solar a better primary) what specific gear would you drop for the 6 24 48 request if the limiting space factor for power controllers or conditioners were 36hx36wx10d
