Dave,
Be careful running an a/c or your ref with that low voltage. That can burn out the motors. At least that is what I learned years ago. Personally I would turn them off or unplugged them if they are straining.

 

Well I have been getting REAL brownouts here in Sibulan. That means I have power for lights and normal stuff but the air conditioner was struggling for power to keep running. Gotta be hard on the old A/C when its not getting the juice to operate properly. Time to sell that one before it breaks :-)
