Your inverter will continue to switch off if your if you battery is

  1. Low i.e. it is not fully charged
  2. Has a low ampere rating
The solution is to get a battery with a higher ampere rating like 200ampere/hour and above, connect it in parallel to the other battery i.e. the positive terminal to the positive terminal, the negative terminal to the negative terminal. This additional will accommodate the excess power needed for the microwave to start up.

Note that it is not advisable, to use this type of power appliance on a small inverter .Use a battery with the same volt rating i.e. a if you use a 24volts battery get another 24volts battery with a higher ampere rating

Duromax xp4000s only puts out 15amps at 3600rpm???? wont carry a 900watt micro wave???

That is double the amperage required to run a 900W oven so the problem could be that the unit isn't producing the correct voltage as to not carry the oven at 15 A the voltage will be under 60V

Most power inverters require the vehicle to being running to operate, and make sure it's the correct wattage, if it's a small watt inverter it doesn't have enough power, as a coffee machine is considered higher wattage, hope that answers your question ?

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.

Why is induction motor saw blowing fuse shortly after starting?

If it is still trying to run as a DC system, it might be that the positive and negative are reversed.

I have a 1500w power inverter that has worked great for abt 2 yrs, I run a dorm size refrig. on it and sometimes a 700w microwave but not both at the same time. The fridge draws abt 180w at startup and abt...

Not likely as low voltage should shut the inverter down. Check your battery anyway. 13.5vdc fully charged and each cell that is bad is about 2.25vdc off that. Sounds like the inverter has had an internal failure and unless you are an electronics tech, beyond your capabilities to repair without serious training.

We havve a Westward 1YAY9 1500W inverter which has worked well for a long time. Now it often stops working after 5 minutes and after it has been shut off for a time, will start again. The pump we run is...

It is overheating. A good test for this is to use a soft gel pack that can be put in the freezer. Use and old towel to wrap the ice pack once and set it on top of the inverter for about 20 minutes. Then use the pump. If it runs longer, the inverter is going bad, and will cost more to repair than to replace. Check all wiring for green corrosion as this can also cause overheating, but the fact that you have the same power draw leads me to a bad inverter. 6.5 amps is pushing a 1500 watt pretty hard, try stepping up to a 2000-3000w Westward.

Bought a powertech 1500w 24v MI5089 switched it on and cooling fans didnt come on are they thermo controlled or faulty i dont want to use until i find out

Hi funtimes, incase you haven't already found out, the inverter that you have has thermally controlled fans, that is that they won't come on unless the unit is getting warm.

My inverter is Roadpro 1500 but cannot power 700W microwave

How good is the connection to the battery? there are a lot of amps that have to flow fast and clamps just don't do it, lugged cables do!

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.

Need to operate the microwave at 230 volts

You will need a step-down transformer of the appropriate power (wattage) and the proper adapter plug for the country you'll be in. You need to look on the back of the microwave and see how many watts it CONSUMES, not how many watts of cooking power it produces. Usually the power consumption requirement should be in the ballpark of twice the power output. For a 700W (cooking power) oven, I would suspect it has about a 1400W power consumption requirement, so your step-down transformer must be rated at least 1500W. That may be cutting it close, so for lower heat and longer transformer life, I would choose a 2000 watt model. You need to be sure it comes with an adapter plug that's made for receptacles in the country you'll go to. One site I found has them for about $60. but I would read up on the subject to see if you need one of an EVEN HIGHER rating since microwave ovens do surge when they start cooking. You may need to use one rated at 3000W or more. More info:
