Google isn't helping me much so far (apart from several links about the
heater giving of a burning smell then stopping working) but there is
one foreign link which related the "1500" in the brand name to 1.5kW.


That might be for 110 volt? Or it might refer to cooling capacity of
1500 watts, with electrical consumption of 715 watts, which would be a
coefficient of performance (COP) of about 2 which sounds reasonable for
a small heat pump.

Thanks - another bit of the data says that it is 230 volts at 50Hz.

Whatever scheme you use you need the VA requirements of the compressor
NOT the watts to get an inverter or genny to power it. You also need to
be able to source the Starting VA of the compressor which will be far
higher than the running figure by several times.

One way to estimate pk current is to look at the rating of the fuse and
knock off a little.

You will soon see the requirements are far too high for a toy genny or a
battery.

Basically this is a non starter. Forget it.
