Hi all,
I'm working on sizing a generator to run my air conditioner.
The air is 5050 BTU, rated at 4.8 Amps.
I'm having a bit of trouble understanding the readings I'm getting when checking the Amp draw.
Unit turned off, meter hooked up, turn unit on, reading is 19.7 Amps.
Unit won't start, fan comes on, stays on.
15-20 seconds later, the compressor kicks in, Amps go to 4.7
Quickly drops to running Amperage of 3.0
So, I let it run for a bit, then turn the thermostat until it drops out.
Amps go to 0.30, fan only.
Give it a few moments, then turn thermostat again.
Amps jump to 18, but won't kick in.
After 15-20 seconds, compressor kicks in, Amps are 3.5 at start of compressor, then drop to normal running Amperage of 3.0.
Unit runs fine.
If the startup draw is 19.7 Amps, then I'm going to need a 2500 Watt generator...and the whole idea goes to heck (too big and bulky).
If the starting Amperage is 4.7-5.0 then I can get by with an 800-1000 Watt generator (very compact and easy to store).
Any thoughts?
Rob
