DESCRIPTION
ALTO is a compact and scalable modular inverter providing
a pure sine wave AC supply.Leveraging the existing DC
Power system, it provides an excellent high power 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 96% reducing
operating costs.
APPLICATIONS
All high power business critical applications and all types
of AC loads. The design is modular and scalable with hotswappable inverter modules which ensures low Mean Time
to Repair (MTTR), reduction in service costs and meets the
changing needs for future expansion.
