Air Conditioner Watts / Power read with a Kill-A-Watt meter
May 27th, 2013 at 4:33pm
 
I had the opportunity to test several different units that are 10.7 EER using a Kill-A-Watt meter.

6300 BTU = 687W at 102F outside

8000 BTU = 778W at 102F outside

5000 BTU 9.7 EER = 759W at only 80F outside !

All were at the high fan setting. As the temp goes up they work harder.

You can see why the EER rating is important, the 5000 BTU one draws as much as the 8000 BTU one! The start up surge is lower for the higher EER units due to using the newer scroll compressors, add about 200W more for surge for those and a lot more surge for old style compressors.

You need to run these with a pure sine inverter or risk overheating the compressor.

Try to buy one with a 10+ EER rating if you can especially for off grid solar use.
