I have this 1000 watt HD power inverter. Its made by PowerDrive. This is what google says about it.

"Continuous AC power output: 1000 watts; Maximum AC power output (surge): 2000 watts. Power AC devices rated up to 1000W/high surge capacity up to 2000W to start. One 3-prong AC outlet. USB port with 5 volts DC output. Heavy-duty installation cable attaches directly to vehicle battery."

I want to mount it in my Jeep Cargo area, or under my pass. Seat. I want one to be able to run say an angle grinder all by itself with the jeep running.It doesnt necessarily have to run an angle grinder but you get the picture. Not just cell phone chargers and laptop batterys. I want to run lights to work on my jeep. or a set of spot lights on a tripod. Maybe a small compressor with 1hp, and 3gallon tank. I can use heavy gauge amp wire right to hook it up?

I also have this one. I want a HD on in the cargo area and a smaller one up front under the seat for chargers, etc. How would i go about wiring both up?
Can my battery and alt. handle two of them say i got it running, phone charger plugged in the front one. And i got a hanging light hooked up in the rear with a blender? Will it be ok.

I would think you going to need a really big Alternator. I'll be watching this thread to see how much amperage you'll need.

tomborsari

i could be wrong, but if you kept the rpm's a little higher while ur in neutral, couldnt that help no matter what alt u have?
i also will be keepin an eye ion this thread cause i have a 136A durango alternator that i haven't found time to put in yet

Pnguyen7

Yea your right.it could work but i think it might put undue strain on the alt.I want to do the durango mod too if i do this. I know having the one 1000watt couldnt hurt. and just run like lights and small stuff but if i can run an angle grinder and light i would love it.

If you're going to use the two inverters just for those purposes, sure, that might work. You will definitely need the Durango alternator before even considering the 1000W inverter.

The owner's manual lists the *maximum* efficiency as 87%, but doesn't say what load that's at. If we assume that that's at the full 1KW continuous load, that's about 1150 watts required to power the thing, or approx 96A at 12V, or 83A at 14V. Normal incandescent lights should be fine to run on this thing. The manual specifically calls out several types of appliances that this thing cannot push because of the type of power it generates.

The inverter sort of approximates AC power by generating a "modified" sine wave. Instead of a nice smooth curve it looks more like a stepped pyramid Devices that use switching power supplies to convert to DC internally, like most computers, don't notice this. Simple things like incandescent bulbs don't care either. However, anything with a transformer in it will suffer greatly, fluorescent lights won't work, and motors won't work right.

The difference in force is like this: with normal sine-wave AC, there is constant pressure as the wave is smooth. Picture this like if you're pushing an object along, you just give it a constant push. With modified-sine, it's more like you're bumping into it repeatedly. Things like electric fans run much slower on a modified-sine output... so you can imagine how an air compressor would behave. So without getting into power factors and the like you should probably only budget about 800 watts of normal load onto this thing for continual operation. Most devices label their maximum draw so that shouldn't be an issue if you just go with what the sticker says.

Aside from the issue with modified sine, your 1HP compressor would overload this thing anyway. At least with other motors (I don't know what kind of crack the vacuum cleaner companies smoke ), 1 HP is roughly a full 15A circuit @ 120VAC - or approx. 1850 watts - somewhat over the capacity of this inverter.

Wiring-wise 2AWG or thicker should work if the run is pretty short. Manual recommends 0AWG if it's going to be a long run, say to your cargo area, which I'd tend to agree with for performance and safety reasons.

Ok forget that compressor. Will a smaller one work. What about just a small angle grinder. What if I just used the bigger one with no small one

salad

Smaller angle grinder should be fine - remember to check the labelling for electrical draw. You should be looking at piling up about 8A or less. Same thing goes for a compressor, 1/3 HP should be fine, you may have luck with 1/2HP. Just don't hold your breath for stellar performance

I take it your XJ has the dinky 90A alternator? I just checked my build sheet from Chrysler, apparently my 99 came with a 124A (I have air conditioning)

Pnguyen7

IDK i have a 96 never got a build sheet tho. I got mine from napa so i can check the site. Ill look. But prolly got the small one

Shop vacs generally peak at around 6A when you first fire them up, but then settle to about 4A. 15A is a ****load of current for a household AC device. My 4.5in grinder pulls about 6A.

That 1000w will pull close to 85amps with the car running. If you put it in the back, I'd probably run 1/0 with about a 100A inline fuse to protect the wire in the event of a short. It'll probably only be able to put out like 10A AC.

i have a dinky little 800w inverter that hooks to the battery with spring clamps.
i've used it with my 7a impact gun, coffee perc, work light etc. not all at once, but it didn't even phase it.

i want to install either a 1500 or 2000w inverter in the cargo area. maybe both... too bad they can't be hooked up in series.

zimdogg

Just curious, but how many times do you expect to need an angle grinder when you're not within reach of an extension cord and power outlet?

Pnguyen7

I dont. But I kno it pulls a decent amont of power.

if a stock battery and alternator can push a 5500watt amp while all the lights are on while the 100W warn lights are on while idling im sure it can handle turning those two.
