Features of the Product
High-efficiency power conversion
PWM method with IGBT semi-conductor device is applied and the high-efficiency of 98% or
higher can be achieved at the rated power.
Digital control
The system is controlled efficiently through the high-performance digital control and it can be
checked through LCD keypad to monitor and display the operation of the inverter including
input/output status, also fault conditions to terminate the operation.
Also, by detecting a voltage in the solar module, the inverter is operated or terminated
automatically.
Transformer-less inverter
As this outdoor type inverter is a transformer-less type, it is suitable for distributed power
systems designed for a commercial scale generation.
Distributed power system and economic feasibility
The photovoltaic system can be installed anywhere where the sunlight is available. Thus,
distributed power can be constructed at a level of building, house, or solar power plant,
which can be used economically.
Maximum Power Point Tracking (MPPT)
Since the output characteristic of the solar cell is to generate, not uniform DC depending on
temperature, humidity, climate, environment, and insolation, the inverter controls the solar cell
module to maintain the maximum power point through the Maximum Power Point Tracking
(MPPT) control.
Easy parallel operation
Once the capacity of the solar cell module is increased, the inverter can be added without
additional equipment via parallel connection easily.
