7 Commissioning
7.1 Verify before Commissioning
PV Arrays
The PV array should be checked before operating the inverter, and to ensure
that the positive and negative mustn’t be misconnect, otherwise, the damage
may be caused to the inverter. Make sure that the open-circuit voltage of PV
array doesn’t exceed the required voltage.
DC Input
Make sure that the DC terminals of the inverter are connected correctly and
maintained consistent with the PV array.
AC Input/Output
Make sure R, S, and T of the AC input terminal of the inverter are properly
connected. Do not connect R, S, and T to the ground pin. Make sure that the
AC-side of inverter is connected correctly, and phases of AC-side are
connected correctly.
Verify of the water pump motor parameters
Check the electrical parameters on water pump motor nameplate: the rated
input voltage and input current frequency, to ensure inverter is matched with
the pump.
7.2 Inverter Commissioning
Choose suitable weather, with enough sunshine, and make sure the normal
operation of your Solar pump 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.
