Translations:Power flow between components/1/en

A stand-alone PV system behaves differently depending upon environmental conditions and the demands of system users. The PV source can generate a limited amount of energy based upon its size and the environmental conditions. The energy storage system can only store excess energy that is not consumed by users/loads, but also has a limited storage capacity based upon its size. The charge controller serves as an intermediary that helps to regulate flows from the PV source to the energy storage system and loads (lighting, appliances. The PV source and the energy storage system will therefore interact in different ways in order to meet the varying power needs of system users. These diagrams do not account for efficiency losses in the system.
