Philips SunStay - A integrated solar street light with lithium-ferro-phosphate battery, solar panel and charger

Philips SunStay is a LED street lighting

SunStay is powered by an integrated solar panel and battery, including the latest solar lighting innovations in terms of performance, quality of light, reliability and connectivity. 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.
