These systems have photovoltaic systems installed on posts associated with batteries that make the system entirely autonomous and therefore ideal for preventing high costs of digging and laying of electrical cables to run electricity to the areas that must be lit. Recommended for towns where streets or dark areas would require high costs to run electrical power. Ideal for private car parks, industrial plants, public gardens, street intersections, areas of environmentally scenic and/or archaeological interest. The lamp post is autonomous, ecological, has no operating costs and is maintenance free. The fact that it is independent from the electrical grid also makes it suitable for safety purposes in places susceptible to electrical blackouts. ECO line HYBRID The EcoLine HYBRID system is made up of a module with photovoltaic cells that convert solar radiation into electrical energy, which is accumulated in a battery during the day and returned by night to power the LEDs. The power is supplied to the lamp by the included battery or the constant voltage driver (built-in or opportunely connected to the 220 Vac electrical mains). The latter can intervene in place of the battery when it is completely flat in order to ensure continuous lighting even with a completely drained battery. ECO line SOLAR The EcoLine SOLAR system is made up of a module with photovoltaic cells that convert solar radiation into electrical energy, which is accumulated in a battery during the day and returned by night to power the LEDs. The lamp is therefore powered only by the included battery. MPPT Controller Charging regulator with MPPT technology, an acronym which stands for “Maximum Power Point Tracking”. These are able to use all the power generated by the panel to charge the battery, unlike traditional PWM regulators that send a lower current to the battery. The battery will be charged with a current of 3.6A instead of just 2.6A which would be used by a traditional PWM regulator. Therefore the battery charge will be carried out with a current greater than 38%.
