It is a solution for areas that are not yet connected to the grid or areas where it is difficult to lay cables due to geographic conditions. The power-independent architecture of SunStay is also very suitable for high security areas, e.g. perimeter fence lighting. This LED street lighting is self-powered and offers hassle-free operation.
