NOVA is a compact and scalable modular inverter providing a pure sine wave AC supply. In conjunction with a DC Power system, it provides an excellent AC backup solution. It uses the latest inverter technology, providing superior energy efficiency in a compact size.
The “Twin Sine Innovation” (TSI) technology eliminates all single points of failure with full scalability; up to 32 modules in parallel and high efficiency of up to 93 % reducing operating costs.
All business critical applications and all types of AC loads. The design is modular and scalable with hot- swappable inverter modules which ensures low Mean Time to Repair (MTTR), reduction in service costs and meets the changing needs for future expansion.
