1.High Efficiency

86.6% (maximum) high efficiency.
It helps to conserve energy and reduce power charges.

2.Increasing the Reliability of Power Supply

The output is a pure sine wave.
D11A can perform parallel redundant operation.
A redundant configuration of N+1 units with a backup unit increases the reliability
of inverter power supply.
Totally independent control with high reliability has been realised.

3.Bypass Function for security

Even if a power failure occurs, switching to the AC input bypass circuit keeps power supply stable.

4.Simple to Add Units

Up to 6 units (6 kVA) can be added.
In redundant operation, a unit can be replaced without the need to shut down its power supply.
A unit can be installed easily in the parallel operation cabinet from the front.
