Question about RTO ATD-5954 1500 WATT INVERTER

1 Answer

My microwave will not work with this new inverter, it is a 650 watt microwave. It will not work in any plug but all other things work in each plug including 1500 watt elec skillet and 900 watt coffee maker. I thought my microwave was bad and bought a new one but it responded the same way when I tried to operate it, it lights up and flashes but has no cooking power, it shuts down.Any idea what the problem is and how to fix it?

There are a couple of possible explanations for this. I have no way of knowing how well your inverter is wired. If you have followed standard inverter wiring guidelines for an inverter of this size you will have eliminated that as a possible problem. Your microwave is more than likely at least 1100 watt input power consumption. I am not familiar with this brand. Some off brands make claims that are substantiated by questionable testing. Your initial surge should be no more than 2200 watts, well within the capabilities of this inverter. My guess would be that your problem is probably with your wiring. If you feel that the wiring is without defect, you may have a faulty unit. I know that dollars are always an important consideration, but I suggest purchasing as large a unit as you can afford and one that exceeds your requirements. Best wishes...

I have a 2500 watt cobra inverter and I'm trying to get my 700 watt microwave to work but it keeps poping the breaker and shutting off Not sure why

Instantaneous surge current can trip the breaker. You need to look at the data plate on the oven to see what the actual draw off the mains is. 700 watts of microwave power is NOT the amount of power drawn when it starts. You have the fan motor and the tray rotator motor to deal with when calculating the correct size of inverter to use with it.

Why does my 900w microwave trigger the LUP code & alarm?

you need at least a 1900 watt inverter with a fully charged battery to run a 900 watt microwave,it uses 900 watts to make microwaves and it uses 700 or so to run everything else.

Inverter problems

3K is a big inverter. Depending on mfr, though, inverters put out numbers for PEAK, not AVERAGE Watts, and have trouble supplying large amounts of surge current on demand. Some appliances with large motors present large turn-on demand, like A/C's, washers, ovens, and fridges and will give converters trouble.
Your Microwave, if it's a big one, like a 1.2 or 1.3KW will ask for a lot of juice when it first turns on. But once it's on for a few seconds will probably be OK.
Get a bigger or different inverter, or a smaller microwave.

I'm trying to run a 750 watt whirlpool compact microwave with a 2500 watt Cobra inverter. The microwave runs normally, but it won't heat. If I plug it in at my house it heats fine. I'm stumped. I load...

I assume your not using a pure sine wave inverter. A lot of electronic devices won't work on a lower cost inverter (modified sine wave) that has a square sine wave, either invest in a true sine wave inverter or don't run sensitive electronic equipment, I'm somewhat surprised you didn't damage the circuit board in the microwave...Below is a link of a inverter that would work if you want to spend the money for one.

Microwave wont run with a 1500 watt inverter why

Depending on the model of the microwave it could draw more wattage than what is put out by the inverter. Don't forget there is a inital spike when your unit first starts and that although an inverter might be listed at 1500 wat that is the maximum and will depend on how much power the inverter is getting in, so if the engine is not putting out enough power the inverter will not put out a full 1500.

I have a 900 watt microwave when i turn my microwave on it blows the fuses in my cable what size fuse do i need

hi there, if you're using your power inverter to run your microwave oven isn't it? surely it is not advisable to plug this appliances for this really consume a lot of power...and eventually overload your PWR Invrter..if you use you power inverter in diff. load like lightings or a small dvd plyer and runs your microwave has no deffect if plug in wall socket and still blown the have a deffective microwave oven..every time you replace the fuse w/ same type or ampereage and still blown you have a shorted power supply...try to bring your microwave oven in service center...nice day..

I have a cherokee 1000 watt inverter.when i try to use my 700 watt microwave,the inverter just shuts down.but any other device i use such as a tv or dvd player works fine.what should I check?

I think you are probably not going to have enough start up power for a microwave.They draw alot of amps on start up and I think your tv or dvd will pull about 1/3 to start.
I have a 8750 watt max watt generator and my wifes microwave is the only appliance in the house other than dryer that will make it change rpms.
Hope this helps you. Thanks

Output Voltage Low

test power out- put if good then ur microwave even though showing 600 watts the amp draw might be higher than inverter out

Need small microwave for inverter on houseboat

Look at the rating sticker on the oven and use the AC power rating as your guide. The cooking power of the oven is not important, but the power it needs from the AC supply is. Voltage times current is the supply power needed (watts), and you want an oven that will draw less than the inverter's continuous rating, less any power being used by other appliances.

For instance, a microwave rated for 120 volts AC at 10 amps needs 1200 watts. Your inverter would be OK with this as long as other devices aren't using more than another 1000 watts. You can't use the inverter's peak rating. That's only for brief bursts, like when the microwave first kicks on and draws some extra current.

Any mid-power (600 watts or so) oven should be OK.

Inverter shut off and turn back on..

Sounds like one of two things are happening:

1. Microwave is drawing too much current, causing internal voltage monitoring circuitry in inveter to go into protection mode.


2. RFI from microwave is somehow being few into inverter causing similar circumstance.
