TheBattery Mobile

TheBattery Mobile is Alfen’s green alternative for diesel generators. It consists of a moveable 10 ft. container based on BMW i3 batteries. The compact design allows up to 422 kWh of energy capacity and up to 300 kVA of power. The system has an outside connection and operation panel with powerlocks and a HMI to connect and operate the system safely and quickly. TheBattery Mobile is often used sites where a temporary power supply is required, such as, festivals, construction sites and grid takeovers.
