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
photovoltaic 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 that R and S of the inverter grid AC input terminals are properly
connected. Do not connect R and S to the ground pin.Ensure that the inverter
output end is properly connected, check whether the AC pump is properly
connected to U, V and W, and the protection ground of t he system is properly
connected to PE.
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 pumping 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.
