HVAC Soft Starters -> Any Good?
Bear with me, because I am having trouble posting here.
I have been reading about these devices called soft starters. They are microprocessor controlled devices that ramp the current to the compressor at startup during about the first second or two. It makes sure the compressor has enough current to function but not the high peak Locked Rotor Amps the compressor demands.
The big advantage is that when running a HVAC on one of these units it controls the LRA reduces it by about 70 percent. It learns how the compressor demands its startup current during successive 5 to 10 startups on shore power. Some claim, though I have not verified, that a 13.5KBTU HVAC can easily be started and run on a soft starter with a single 2000 watt inverter in eco mode.
There are several manufacturers of these units:
