to set
inverter time and date on the parameter setting page.
Method 2
:
Please connect GPRS antenna to the inverter as section 6

4 Off mode
When the DC voltage is more than 200Vdc
,
inverter will be powered on and enters the
"waiting" state.
At
this mode
,
inverter will check the system parameter
.
If the system is normal and PV
voltage is more than 250Vdc
,
inverter will try to connect to the grid
.
At this mode
,
inverter work normally
,
and the shows
the power delivered by the inverter to the grid
.
When the DC voltage is more than 250Vdc
,
inverter converts the DC power generated by
the PV modules into AC power and supplies them to the grid
.
When the DC voltage is lower than 250Vdc
,
inverter will enter into “waiting” state and
try to connect to the grid
,
at this status
,
inverter consume very small power to check the
internal system status
.
Note
:
only when the PV modules supply enough power
(
voltage
＞
200Vdc
)
then the
inverter will start automatically
.
Power or fault code indicator light
Inverter intelligent control system will continuously monitor and adjust system
status
.
When there is a fault detected
,
LED will show the fault message
.
Note: Please refer to section 8
.
2 to check the fault message and take corrective measures
.
When the sunlight is weak or no light
,
inverter will stop working automatically
.
When it
is off
,
inverter will not consume gird power or PV module
.
At the same time, the LED of
inverter will be turned off.
Note: When
PV string DC voltage is too low(
≤
150Vdc
),
inverter will be off
.
Inverter current operation status can be visually checked from LED display directly

Description of LED status
Position
of LED
Type of LED Inverter status LED status
A
PV voltage
indicator
light
PV voltage reaches grid
voltage Green light is on
PV voltage does not reach
the grid voltage Light is not on
B
AC voltage
indicator
light
Inverter is in the grid state Green light is on
No AC voltage Light is not on
With AC voltage, inverter
is in the grid countdown
state The green light flashes
slowly, and the alarm or
fault indicator light is not on
