I have a small vacation home off grid. The only power source I have is a DuroStar DS4000S portable generator. I wish to purchase an inverter-charger in order to be able to run appliances continuously, but I'm not sure how many watts the inverter should be. I've done some research already, but I'd really appreciate some help making sure my calculations and my understanding on how everything should work is correct.
My first question is, since my generator " cranks out 3,300 constant running watts of power (and a peak of 4,000 watts)", that the max watts my inverter charger can use is 4,000 watts?
And my second question is how many watts does my inverter need to be?
I have a Frigidaire FRT21P5AQ9 refrigerator. Part number 240379012 on page A-5 of PDF link for anyone who wants to double check. The specs are Wattage 140 to 185, Amps (running) 1.1 to 1.6, Voltage 115 VAC (127 VAC max) that needs to be constantly running. (I have diabetes and need to keep my insulin cool).
I also have a GE JGBP35WEA7WW Gas Range. The specs are 120V; 60Hz; 5A.
I used this " "DC to AC amperage conversion run through an Inverter" calculator to help determine the amount of Watts for each device but I'm not sure if I'm using it correctly.
For the fridge I put the max volts (127v) and max amps (1.6A) and I got 203.2W. And for the stove, that'll only run when I'm cooking, I put 120V and 5A and I got 600W. So together that would be 803.2 watts I also have a number of other devices, but unfortunately I don't have the model numbers for these devices with me right now. They'll include a boom box radio, a cellular phone charger, some lights, etc. Can someone help me determine the minimum and maximum watts needed for the inverter-charger I purchase? Actual product recommendations would also be helpful. Thanks in advance!
