Operation
5.1 Inspection before operation
Check as follows before operation:
(1) Detect the voltage of the components is in the allowable input
voltage range of the inverter;
(2) Detect the voltage of the AC port at AC side is normal;
(3) Check the inverter is in good grounding;
(4) Ensure all switches are “off”;
(5) Ensure all electrical safety precautions are clearly-identified on
the installation site.
(6) Confirm the handheld keypad or communication module is in
correct connection.
5.2 Grid-tied operation
Please start the inverter as follows:
(1) Switch on the integrated DC switch;
(2) Use the handheld keypad or communication module to set the
time, date and area of the inverter;
(3) Switch on the breakers at the AC side;
(4) Observe the LED indicators and information displayed on the
LCD
screen.
Run
Green indicator blinks, others off: the inverter is power
on and in self-inspection;
Run
Green indicator on, others off: the inverter is in power
generation after self-inspection----successful commissioning.
“Warn” or “Fault” indicators are on or blinking: the inverter is
power on, but fault occurs.

Connect the 485 port of accessories to the RS485-M(4-10kW) or
RS485(12-40kW) port of the inverter; for the ACF inverter,
RS485-M(4-10kW) or RS485(12-40kW) is to the upper PC and
RS485-S(4-10kW) or EXT(12-40kW) is to the ammeter.
5.4 Regular maintenance
Stop the inverter as follows it needs maintenance, inspection and
troubleshooting:
(1) Switch off the breakers at the AC side;
(2) Switch off the integrated DC switch;
(3) Contact with customer service staff or local dealers.
