With Duraco 3E PV system, the photovoltaic panels generate electricity during the day for initial consumption. The excess energy that is generated will be stored in a battery for later use when there is no sunlight, such as during the evening.
In case both the photovoltaic system and battery power are insufficient due to unforeseen circumstances, the 3E inverter will switch automatically to CEB grid as backup. This helps to ensure a stable and uninterrupted supply of electricity while reducing your dependence on Grid energy.
