System Commissioning Checklist - Bergey XL-15 Installation Quick Manual

 Ensure all turbine wiring has proper insulation by performing 1000 volt
megger testing. Do not test wiring with turbine or inverter in the circuit.
(see page 23)
 Check all inverter and dump load connections.
 Test the resistors in the dump load, a correct reading should be 10 ohms
between the buss bars
 With the emergency stop closed bring on grid power to the inverter, ensure
dump load fans come on and proper grid VAC is being supplied to the
inverter (see page 24)
 Pull out the emergency stop ensuring the inverter fully powers up and
starts the five minute initialization process

Observe the end of the initialization process hearing the humming and
contactor close, the inverter should now be in a "waiting for wind" state

Remove the phase to phase short in the down tower disconnect

Test for balance phase to phase voltage from the alternator (see page 25)

Observe the unit transfer power, ideally to maximum power output
