We got our share of snow in my area and many people had an outage
lasting quite a while. I'd like to be able to power a freezer on
inverter powered from car battery for extended outages. My freezer takes
115W, 145VA to sustain operation, but the compressor is rated at
7.5LRA(locked rotor amps, which you can use to estimate your
fridge/freezer's peak power requirement) and I guess that comes to 900
peak watt.
The 140W inverter I mainly use for charging digital camera
batteries in my car definitely won't start this freezer, but my
700W(1000W peak) inverter can start it(barely.. it beeps when the freezer
starts). Is there anyway I can run a freezer/refrigerator on an inverter
short of getting an inverter with a peak wattage that can accomodate 120V
* compressor's LRA? It's really foolish having to dedicate a 700W(1000W
peak) inverter for a 115W freezer.
Searching the internet showed there's an "easy start kit" that lower's
peak current by starting compressor slowly, but I haven't been able to
find any.
I suppose I could use a series reactor to restrict the starting current
but could the comrpessor start up with restricted starting current?
