Victron 3600W Auto 115/230 Isolation Transfer output voltage

With 118 volt input to transformer and no load applied, the output voltage is down to 108 volts. With same voltage input (118 Volts), output voltage drops to 0.8 volts with light load (<10 Amps) applied. Shouldn't output voltage be same as input voltage when no load is applied? What causes output voltage to drop to near zero volts when load is applied?

I thought I read (someplace) that the output voltage should be slightly higher that input voltage. To compensate for lower than normal voltage from the pedestal. Maybe you have it connected backwards?

Are you measuring the voltage under-load?

Yes, there is a gain in the transformer.
