Make sure your connections are good between the inverter and 12 volt supply. To small wires will not work, chances are it has to be connected directly to the battery with good sized wires.

SOURCE: Low voltage output from inverter

I am thinking this a high impediance device problem and this is normal operation - the user manual of my inverter warns about use with high impediance devices - if not I am interested also...

SOURCE: Wiring the 1750 watt eliminator direct to the main panel

DO NOT DO THIS! If I understand you correctly you want to have three ways to have 110 power in your motor home--- (1)Vehicle 12V to inverter to main panel. (2)Generator to main panel. (3)plug the main panel into 110V. If any two of these are connected at the same time and they are both live, somethings going to blow. That's because with AC, the two sources must be synchronized in their cycles very precisely. The utility company connects their power plants together on the grid only with the aid of precise controls. But the really serious problem is the same reason they invented transfers switches for home generators -- if you were connected to (3) and the power went out, and you connected (1) or (2) without disconnecting the dead (3), you will backfeed power to the line outside and you just might kill the lineman who is trying to fix the power outage.

SOURCE: why would my new 1500 watt inverter readout show

It would show overload if you're drawing more power than it can supply. 1500 Watts is a very high output for an inverter but that is the maximum it's capable of. As with any electrical supply you should not draw the maximum power it's capable of as this can cause it to burn out. Around 1200 would be the max you should draw continuously. You need to check the power requirements of whatever you're running on it. Also you need to check that it's capable of taking 13.8 volts. If 12 volts is the recommended input, putting in 13.8 will increase the voltage output which could damage appliances being run on it.

SOURCE: My cobra 1500 watt inverted doesn't come on wen I

You may not have adequate input voltage. And unless you are hooking up to a forklift battery, the battery will not have adequate current delivery capability for any more than a few seconds at full power of the inverter.

1200 Watts is 100 Amps. 1500 Watts is in the neighborhood of 130 Amps.

Honda eu3000is generator surges

Inverter Generator Benefits
  • The EU3000 series generators are inverter generators. The generator features an alternator, which produced high-voltage, multi-phase AC power. This power is converted to DC power and then converted back to AC. This process is controlled by a microprocessor and is necessary to provide stable, consistent power capable of running equipment sensitive to power surges. This type of generator provides higher fuel efficiency and lower operational noise ratings in a lighter model than home and work generators produced by Honda.

EU3000i Handi Specifications
  • The Honda EU3000i Handi is a 3,000-watt inverter generator that features wheels, folding handle and a recessed convenience light. The engine is a Honda GX160, which features a 163-cc displacement. The AC output is 120 volts, with an average rating of 2,600 watts and a maximum production of 3,000 watts. There are three receptacles to include a 20A, 125-volt duplex and a 30A, 125-volt locking plug. The DC output is 12 volts and 100 watts. The EU3000i can hold 1.56 gallons of unleaded fuel, which will provide consumers with 3.6 hours of run time at 25 percent load for 7.7 hours.

Trace SW 5548 output ac voltage is 164 volts, under a medium to heavy load it will lower to a 142 or 144 volt output.

Is your 12 volt source able to supply 1500 watts of power? You can't draw more watts out than you put in. What is your 12volt source? A standard automotive alternator cannot make close to 1500 watts.

What is the cprimary load on a 12volt to 240 volt 300watt inverter

Ohm's law tells us that: volts = amps x resistance and watts =volts x amps. Watts (300) = volts (240) x Amps (?); or 300 / 240 = 1.25 Amps That means the inverter can supply up to 1.25 Amps to a 240 volt load.

The primary is 12 volts, this is just 1/20th of the secondary 240 volt output. Since the best you can ever get is 100% efficiency -this means you'll need to supply 20 times the current. 1.25 Amps (at 240V) x 20 = 25 Amps (at 12V). As a check, from above Ohm's law that states Watts=Volts X Amps we get: 12VDC x 25Amps = 300Watts. Check!

Some side notes. The Ohms law used above is for DC circuits and purely resistive loads on AC circuits. I do not know what your 1.25 A @ 240VAC load is - but I suspect it won't be purely resistive. Also, since we're working with an electronic inverter as opposed to a transformer and DC rectifier there are some things that push losses higher. You might need to provide a 30 Amp 12 VDC source voltage in order to provide the 1.25A @ 240VAC output. Lastly, I wouldn't not run the output at maximum for long periods of time - or at all. 1 Amp @ 240VAC would be much better.

I hope this answered your question & good luck! Please rate my reply - thank you.

Yesterday I bought an STP-120 SIMA power inverter

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

I just bought a RoadPro 2500 and i want to buy like a dorm fridge how many watts or volts size would work??

If you are referring to the RoadPro RPPI-250
  • 2000 Watts Continuous Power
  • 2500 Watts Power Output @ 10 Minutes
  • 5000 Watts Peak Power Output.
  • A small fridge will use about 500 -700 watts, with startup wattage at around 2000watts.
  • So, a dorm fridge will work fine.
  • the RoadPro converts DC to AC voltage, so a regular 120 volt dorm fridge will work.

    2000 watt inverter blows 60 amp fuse under load

    I have a background in electronics so i hope i can help. Now after reading this i have the feeling this item does not put out 2000 watts cause if that were the case it should draw somewhere near 147amps. This is because to find out amps you need to take the 2000 watts and divide it by 13.6 volts (assuming what the vehicle runs at) that gives you amps. watts/volts=amps.
