Test the work of an autonomous home as shown in the video

Conclusion 

The “autonomous house” system is especially attractive for objects remote from the power grid: detached homesteads (farmsteads), hunting lodges, hotels in protected areas, sawmills, greenhouses, distant army garrisons, etc. But even near the power grid, an autonomous system will reduce the cost of uninterrupted power supply, create the necessary reserve in case of breakdowns and accidents at substations. And connection to the grid can serve as a guarantee against all sorts of troubles with your power system, such as long inclement weather or lack of energy in winter. The greatest effect of implementing an “independent home” system can be obtained in places where neither power lines nor gas pipelines are available.
