Just tested if you have power lifting enabled with an 800W heater load it will run it at around 140VAC and 300W.
For a 800W (66ohm) in power lifting i would expect it to run on 200VAC and 600W.
Why is this?
if it is then plugged in to charge, is slowly ramps up the voltage…
the thing keeps rising the voltage even if its already at max power. and then it goes into over current protection.
