Tiger in the tank, back-up in the cellar: self-sufficient emergency petrol station

In the tranquil town of Altenmarkt in southern Bavaria, the Wurm family operates a fuel and lubricant trading business and a petrol station with 8 petrol pumps. Electricity is produced by a photovoltaic system on the roof of the company’s building, which works together with a combined heat and power plant in the cellar.

With the help of a Tesvolt battery and 3 SMA Sunny Island inverters, the company can efficiently store the electricity produced for their own use. But the powerful battery is capable of so much more: In the event of a power failure, the system can provide backup power and even cold start heavy load-consuming technical devices such as diesel pumps. The petrol station thus qualifies as an emergency fuel station and is officially registered as such with the German Federal Office of Civil Protection and Disaster Assistance
