I have a 3000 watt inverter,with 3 plug in outlet..how much power do I get from 1 outlet..this equipment is hook to 6 12 volt battery charge by a 60amp controller and 3 solar panel of 265watt each???

An inverter changes 12vdc to ac. If it is 35 k it may be 35000watts. Therefore it needs that many watts or more to run it efficiently. Check with a manual for information on how many watts it needs. Most average homes need 10000watts or 10kilo-watts. If you are making DC Volts you need to hook up an AC LINE INTO YOUR VACATIONER and this will give you standard a.c. for refrigerator and overhead lighting. With that 35k watts if that is so you may need a 240 VOLT AC HOOK UP.. Some trailers use AC and some DC . Mine has an inverter but I think it uses120 volt AC . Some VACATION Homes have DC possibly 4 -12volt batteries or more but those batteries are each possibly 300 AMPS at. around 14.5 volts DC. Watts =VOLTS x AMPS . 14.5 X 300 = 4350 X 4 =17400 Watts or 17.4 k watts . 120 VAC input times 15 AMPS = 1800 watts standard a.c. But with 240VAC x 25AMPS = 6000 watts. Along with those 4 batteries it would have plenty of power to run it. If the Dc was hooked to an inverter it would produce a.c. Instead of DC. Inverters are all different so check the wattage being output and input.

dear see that :
1- the range of voltage which inverter work between it for example 180-260 v
2- most small generator voltage reach more than 260V so the inveter not work
3-check the frequency of genaratoer if it not fix the inverter will mot work

I'm sorry that I can't help you, but if you're in a hurry, you can visit the Magnum website at: http://www.magnumenergy.com/Service/Servicefront.htm and try to find your model's online manual and search troubleshooting advice or you can email customer service at
[email protected] and they should at least be able to lead you in the right direction.

A few questions: Does this problem remain even when there is at least a 10+ watt load on your system? is your Magnum in a hot environment? Does your inverter feel extraordinaryily hot? Have your batteries outlived their lives? Have you cleaned all the connections? Even if they 'look' like they don't need it?

All the best to you.

Hello, I hear you. Was the reason to supply 240 volts? When you try the inverters separately, do you get 120Volts output? Let us look at the units working individually first and go from there.

Hi Gena, the inverter is a 400 watt unit. This is not a rating for a continuous load. You do not mention which fuse is blowing. This could be the fuse in the inverter or the cigarette lighter (power source) fuse. In either case, a fuse blowing could be a short circuit, something in the inverter shorted, or too much load. I am going to look at the too much load side of things. Not knowing how many laptops are being used, with the inverter if you have a 20 amp fuse in the cig lighter, this will allow you 20 amps X 12 volts = 240 watts. I would not run the inverter over 240 watts because of overheating issues. So, 240 watts will run 3 laptops. Just the laptops. Most laptops draw around 70 watts. check your power supplies on them to find their rating. If you exceed the 240 watts by combining the ratings, then you can expect trouble with your inverter. It will give 400 watts, but this is a temporary condition only. Another inverter will be needed or a larger one installed and it being connected directly to the battery (with a fuse of sufficient size installed). You could also (let us say there are 6 computers) charge and run 3, and the other 3 are running on their batteries. After an hour, switch so that the 3 running on batteries now are charging as well as running. The other 3 are now charging.
I hope this helps. If you have any other questions please provide additional information. Such as the size and location of the fuse blowing. The laptop power supply ratings.
thank you

In order to get 230 volts out of any 115 volt inverters you would need to be able to hook the outputs up in series with each other. If your inverters have outlets there is no way to do this other than completely dismantling both units and then I wouldn't advise it. As a licensed electrcian and electronics tech I've sometime done things like that but only as experiments or in emergencies.
If your units came with a power(+) and ground(-) you could then hook them up in series by fastening the (+) from one unit to the (-) of the other, then tape them to insulate them. You should then show 230 volts from the two leads still available. On the battery side you will still hook both postives(+) to the positive(+) and both ground(-) to the negative(-).
Notes:
* Depending on the internal wiring of your units the above description may not work and could damage or even ruin your inverters.
* Although you may get 230 volts this way you will not have more power(watts,Amps) than listed for one unit and you may even have less.
* You need to also beware this could VOID any warantees and shorten the life of these units.

Yes, just be sure connections are heavy enough wire, and obviously the inverter uses 12 vdc input. Hook jumper wires positive to positive, negative to negative, on all 12 volt batteries. Deep cycle batteries will work better than car batteries. Just remember, when re-charging them, that they last longer when charged slowly, so don't use a high amp setting on charger and to monitor them closely, and do it in a well ventilated area, away from any ignition sources.

a very thick one,,,like a baby battery lead on your car,,,its a very bad idear to have it so far away from the battery point, you would be far better off finding a closer place to put it as the volts drop off would have a big drop in out put on the inverter,,,also thats one big mother of a fridge to use 3000 watts????
you need a small power station to run it,,and if it do use 3000 watts your inverter is far to small to do the job, read the out put plate on the inverter,,it says 3000 watts max? not all the time,,,,thats about 2000 watts realy running contently and the whire to feed the inverter will need to carry about 30 amps so your car battery is say 90 amp hours plus the volts drop off, you would be lucky to have the inverter running for 3-4 hours before your battery go's is very flat on you!

Question does not seem to match this inverters capability.

INFO:
This Power Inverter converts vehicle’s 12-volt DC power into household 115-volt AC power. AC and USB outlets power and/or recharge personal electronics.

We have owned one of these Power inverters for over a year now and have run a great deal with it, from TV to drill press PC and any thing that was small and that could run from my car. Very nice product.

SET UP: Connect wires. ensure correct polarity, push button on top. Plug in 110 volt appliance.

Hope this tip was of some use.

you inverter was not fully charged because it requires a 110/220 v ac as specified in the manual; to charge it so it is impossible for the aircraft 15vdc to charge it
