Procedure 2: Screw the handle of circuit breaker at the DC side to "ON" position.
Procedure 3: It takes about 60 seconds to automatically initialize the power inverted circuit and
equipment. Than the "POWER" LED lamp on control panel will be on.
Procedure 4: If the DC voltage is lower than the starting voltage (equal to 450Vdc), the touch
screen keeps shown "Waiting" (in standby).
Procedure 5: If the DC voltage is higher than the starting voltage (equal to 450Vdc), the inverter
will inspect the grid connected conditions. When conditions are satisfied, it will automatically
switch to "Normal ", at this moment, the "OPERATION" lamp will be on.
● Automatic power-on
When the power-on conditions both at DC and AC sides are satisfied, the inverter will be powered
on automatically. After the DC input or AC grid fault is demolished, the inverter will also be
powered on automatically.
● Manual power-off
In the operation process of the inverter, we can power off the machine through the "OFF" button
on the panel. At this moment, the inverter stops work, and stops to transmit the DC energy to grid.
CAUTION!
After manual power-off, the machine must be powered on manually, otherwise the inverter is
unable to power on.
It still maintains voltage after manual power-off!
5.4 Pilot operation completion
The following procedures shall be carried out after the inverter is grid connected.
Procedure 1:
Inspect whether abnormity exists in the inverter, such as excessive
noise,
excessive heat, abnormal smell or smoke.
Procedure 2:
Measure whether inverter connected grid voltage, current and THD are stable.
