Solar Inverter EVM

Hi,

I'm using the 'Solar Inverter HV DC - AC EVM Kit' (with Concerto).

Looking at the documentation 'Solar HV DC-AC Kit User Guide_Rev1.0.pdf' sections

'3.3.2 Open Loop Build' and

'3.3.2 Close Loop Build without PLL'

seem to imply that if I connect a resistor across the inverter output (I'm using 1K Ohm) and apply 380VDC to the input, after pushing SW1 to turn on the inverter, I should see a sine wave at the output. But what I see is a 360V square wave. Am I misinterpreting the documentaion?
