2.1.8 Product features
(1) High efficiency power conversion
It achieves highly efficient power conversion in PWM format by using IGBT semiconductor device
with high efficiency of more than 96% of the rated output.
(2) Digital control
System control is more convenient through the use of high-performance digital controller that
allows confirmation through LCD keypad. Moreover, operation, input and output status, and
abnormality of inverter are monitored and indicated, and inverter will be stopped in the event of
occurrence of abnormality. It also gets operated and stopped automatically by detecting the
voltage of solar cell module.
(3) Transformerless inverter
DSP-123K6-OD inverter is a transformerless type solar cell inverter appropriate for dispersion
type power system designed to be appropriate for industrial, building and household uses.
(4) Dispersion power system and economic value
Since solar power generation uses power generation format that can be installed at anywhere with
sunlight, it is a format that can achieve economic use due to its ability to establish dispersed
power in the units of building or residence and solar power generation plant.
(5) Maximum Power Point Tracking (MPPT) control
Since occurrence of direct current that is not uniform in accordance with the temperature, humidity,
climate, environment and insolation given the output characteristics of solar cells, inverter controls
the solar cell modules to maintain the maximum power point through MPPT control.
(6) Ease of parallel operation
If the capacity of solar cell module increases, it is possible to easily connect additional inverter in
parallel to increase the capacity without the need of separate additional equipment.
(7) Convenience of installation and operation
It is designed to allow easy and safe connection between solar cell and system power by using
dedicated connector. It is also designed to indicate the status of inverter through the frontal LCD
keypad in real time. In addition, installation is more convenient than the separate connection-board
installation method since it is in integrated junction box format.
(8) High reliability and low noise
Factors that induce defectiveness were reduced by optimizing the inverter components and, in
particular, high reliability and low noise were realized by removing inverter-cooling fan with
mechanical lifespan.
(9) Electromagnetic conformity (EMC)
It was manufactured to be appropriate for household electromagnetic conformity (EMC) by
optimizing the inverter power circuit design (KSC IEC 61000-6-1, KSC IEC 61000-6-3, KSC IEC
61000-6-4).
