Title: inverter to supply heat-pump
Post by: paul on November 04, 2006, 09:15:14 PM
Hi all,

Sorry if this has been covered elsewhere, I run a search, but can't find an answer...

Can anyone say if a heat pump can run off a modified sinewave inverter, or should I use a pure sine wave inverter?

Thanks in anticipation

Paul

Not sure. I assume you could run from a modified sine wave inverter, but cannot say for sure.

Please also bear in mind that the inverter must be able to supply significantly more than the rated input of the compressor - this is due to the large start up surge for compressors, also, bear in mind that it is a highly inductive load
