Invertor size for a refrigerator
I have a refrigerator rated at 6.5 amps max. Would a 1000 watt pure sine inverter be sufficient? Nothing else would be on the circuit.

- 6.5 amps at 120 is roughly 800 watts max running. compressors are generally 2.5 to 3x starting surge so around 2000 watts.
So if the inverter is a 1000w contineous duty with 2000w surge it should but on the edge. If that is a typical cheaper brand inverter that is 1000w surge and 500w contineous then nope.
Look at the actual ratings on the spec sheet not the box label/title. Also need to look to see if the individual outlets are rated at full capacity or if each provides half (also typical of no name brands) - Others have posted they have had success with running their fridges on 120v with 1000w inverters. I doubt it matters whether PSW or MSW for a fridge. Only a few things won't work on MSW.
Of course, if it is not a big dollar issue, a PSW will be sure to run anything, so that would be the choice in that case for max flex. - Amps times volts equals watts. Also inverters are not 100 present efficient.
