When Hurricane Katrina struck the Gulf Coast of the United States in 2005, tens of thousands took refuge in New Orleans’ sports stadium, then called Louisiana Superdome. The Superdome suffered extensive damages to its impressive structure, and power failed immediately. The back up generator was no match for the most destructive storm to hit the US. This is one example of many public storm shelters that exist throughout urban cities. Whether the site operates as a protection shelter, school, or entertainment arena, it’s important to consider if they are equipped to brave extensive grid outages in the event of natural disasters or power failures.
In Romania, the Cluj-Napoca City Hall was ready to transform the new Polyvalent Hall (Sala Polivalentă), a sports and entertainment arena, into a hybrid fortress that would provide reliable energy during critical grid outages. This spectacular multi-purpose venue can hold up to 10,000 people, and is located in Romania’s second most populated city. The result is a 36kW back up and self-consumption solar and storage system.
The Conext XW inverter/charger proved to be the perfect choice for this installation. The system now powers the sports and entertainment complex for more than eight hours during the night and fifteen hours during the day, using solar energy that is stored into the battery backup system.
