Commissioning Guideline for solar
pumping inverter
10 Commissioning
10.1 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, 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
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.
AC Output
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.
After finishing the above information, then begin initialization.
