Front Panel
Operating Inverter is quite easy. During normal operation, Inverter runs
automatically. However, to achieve maximum conversion efficiency of
Inverter, please read through the following information:
1. Automatic ON-OFF: Inverter starts up automatically when DC-power
from the PV panel is sufficient. Once the PV-Inverter starts it enters
one of the following 3 states:
z
Standby: The PV string can only provide just enough voltage to
minimum requirements of the controller.
z
Waiting: When the PV string DC voltage is greater than 100V,
Inverter enters a “waiting” state and attempts to connect to the
grid.
z
Normal operation: When PV string DC voltage is greater than
150V, Inverter operates in the normal state.
In this state, it feeds power to the grid.
Inverter automatically stops when the PV power is
not enough.
2. Starting-up display sequence: Once the PV power
is sufficient, Inverter displays information as
shown in the flow chart to the right.
3. Change display information: During normal
operation, LCD shows the detail of PV-Inverter.
On the other hand, the display is setup to
automatically indicate the supplying power to the
grid. Each subsequent press changes the display
by press the “Function” key on the front panel.
