Smart Energy Storage

Schematic Overview of the System

A battery storage system essentially consists of several key components: the battery module, a battery management system (BMS) for monitoring and control, and an inverter that converts the stored direct current (DC) into usable alternating current (AC).

The system is supplemented by a control unit for communication with the photovoltaic system and, if applicable, the home’s energy management system. All components are compactly and securely housed in a single enclosure—ensuring efficient, reliable, and long-lasting operation.

New installation without GreenBOX® and without emergency power

2. New installation, including GreenBOX® and emergency power circuit

 

New installation in an existing building, including GreenBOX® and emergency power transfer

Installation in combination with an existing system and an existing inverter

Battery Storage System

ÖkoFEN electric’s heat-intelligent battery storage system can be integrated into existing PV systems at any time and is ideally suited for use in combination with an ÖkoFEN heat pump and pellet heating system.
