- Thanks to this technology, lifetime of energy storage
will be expanded and output voltage can bestabilized.
System diagram- Scalable up to 360kVA (6 in parallel), with one Bypass unit panel when 2 to 6 in parallel.

Normal (110% ≥ Vin ≥ 90%)※1- Conventional system has only one way to backup orcompensate voltage sags.
This model can compensate voltage fluctuations
including shallow sags and swells WITHOUT using
energy storage device as Dual Backup Mode by
3 level inverter technology.
