Those who equip photovoltaic installations with a storage system are mostly interested in increasing the on-site consumption of generated solar power. However, people often forget to consider that these kinds of battery systems only reveal their full potential through their multiple uses. In addition to allowing operators of photovoltaic installations to significantly increase on-site consumption, a storage system also enables them to reduce their dependency on utility companies and ensures that power will continue to be supplied without interruption should the public power grid temporarily fail.
