2.1.4 Preparation of devices or components for operation
As the preparation for operation may be changed dependent on the installation environment more or less,
prepare necessary materials and parts, i.e. – Multi Tester to check voltage and wiring, gearing tools to install T-
type hanger and etc.
2.1.5 Installation
To prevent the lifetime or performance of the inverter from being depreciated, install the device exactly,
considering its installed position or direction, or peripheral space.
2.1.6 Wiring
Connect solar module input (DC) and grid power (AC) by using connectors . If an accurate connection is not
made, there can be problem in the inverter or peripheral devices and pls. wire carefully.
2.1.7 Construction of Solar Power System
The inverter requires the correction connection under the right selection of peripheral devices. Incorrect system
construction and connection may make the normal operation impossible or cause a serious declination in
lifetime. In the event of worst case, the inverter may be damaged by fire, and use this device in right manner in
accordance with the contents and notices in this manual.
2.1.8 Specific Features of the Product
(1) High Efficiency Power Conversion
The inverter converts the power in a high efficiency using IGBT and has high an efficiency characteristic of
96% or more at rated power.
(2) Digital Control
It’s more convenient to control the system through digital control with high performance. You can check the
system through LCD keypad. LCD screen monitors and indicates the present condition of operation, input
and output and any abnormality of the inverter. And its operation stops in the event of any error. It detects
the voltage of solar cells to operate or stop automatically.
