system. Try to ensure that inverter work under high output
power, high output frequency as much as possible. Please
make sure the following condition before commissioning.
●
Ensure that the inverter is connected correctly to the
AC motor.
●
Ensure that the polarity of PV arrays is correct.
●
Ensure that ac inputs R, S and ground connections
are correct.
●
Check whether the system pipeline is unobstructed or
not;
●
Switch on the DC-side circuit breakers.
After finishing the above steps, then begin initialization.
