5.4 How to Operate
Checklist prior to the operation
Check the status of wiring in the inverter and its installation.
In particular, check if the input polarity of solar cells is connected accurately or if the connection
of the grid line is connected correctly.
Supply the DC power of solar cells to the inverter. Once DC power is supplied, the inverter will
check automatically the status of AC power, count down 300sec, and run automatically.
Check the ON/OFF status of the DC switch at the lower part of the inverter.
(At this time, PV power is provided to the inverter with DC circuit breaker)
Automatic operation
The factory default value is set to automatic operation mode.
If a voltage in the solar cell module is increased to the setup value due to the sunrise, the inverter
operates automatically.
A voltage in the solar cell module is decreased at sunset. Once the voltage is below the setup
voltage, it is stopped automatically. The grid power is always monitored and operation is stopped
automatically once fault state is found.
Stop during operation
If the inverter needs to be stopped during operation, the DC switch is turned OFF or the grid is
blocked to stop the operation.
Warning!
Note that the figure displayed in the operation and installation manual is explained without the
front cover for the purpose of detailed explanation. However, the front cover must be installed
according to the regulation when the product is operated before the product is operated
according to the operation and installation manual.
