sure it was the compressor was 100%? More likely the circulation pump, as the compressor maxes out at 78 or 80% IIRC
The fan being at 100% probably means it was due a defrost, as the speed is pressure related. You'll see the EEV increase in steps too as it tries to compensate.
We're doing pretty well here in our cold humid dip, ASHP consumption has maxed at 28kWh for a 24hr period, for all DHW and heating our 250-ish m2.
