Abstract
A network is disclosed of a plurality of outdoor lighting units. Each lighting unit comprises a light fixture, for example a LED lamp; a power generating means, such as a solar panel or a wind turbine; and a storage means for electric energy, for example a battery. The energy storage means of neighboring lighting units are connected by a conductor. An imbalance in power generation or power consumption results in a balancing current through the conductor. The balancing current equalizes the charge levels of the energy storage means in the system. In an embodiment the conductor comprises a single core wire and ground.
