Witch Magnum Inverter?

[familyof3]

New to the power inverter's. Looking at the 3000 Watt Magnum Hybrid and the 2800 Watt Magnum. From my understanding the Hybrid will have a 240 Volt output and the 2800 Watt puts out 120 Volt. I only have 4 6 Volt batteries and looking to add 4 more 6 Volt batteries to my battery bank. Any help would be appreciated about on this.

Magnum seems to have mostly abandoned 48v but others like Victron still support it.

Magnum still makes 48v inverters and their new charge controller does 48v. How is that abandoning it?

Which witch is which?

If this is to support Walmart occasional overnight stops, the stand alone inverter will support you well. MS2000 vs MS2812 is not a large cost jump, and gives you a bit more head room for usage.

If you are going to start boon docking frequently, then also consider adding a good monitoring system at the same time. If going with a Magnum MSxxxx series, then go ahead and get the BMK Meter and ARC-50 remote monitor, perhaps the AGS and SBC components at the same time. Having all components from the same manufacture can simplify install and tech support. If adding Solar in the future too, they have a PT100 controller that also plays well with all of the other components. When adding 4 more 6V's, remember that it's best to have all age wise matched batteries, so you'd be looking at installing 8 6V's.

Back to the Hybrid vs simple PSW Inverter. The Hybrid can also save you some funds if you have a solar set up, and are plugged in for a month at a location that charges you electricity on top of rent space. Some use the Hybrid with their Solar and Battery Bank to split the load between house supplied and metered powers. So it does provide a few more options then just running with a small generator:)!

Good luck to you,

The MS series would be fine. MS2000 up to MS2800 I think would suit you well.
Yes you could run at least 2x A/C on generator and run the microwave or hair dryer off the inverter at the same time. 4x GC2 is about minimum and certainly if you go to 8x GC2 you will be in great shape.

Now I will say I am a proponent for separate components. Easier to tailor the system to what you need and if something malfunctions it is easier to diagnose and repair only what is needed. So I recommend a stand alone inverter of 2000 to 3000 watts, separate transfer switch(es) and separate supplemental charging system if needed. Not sure Magnum has such an inverter so I recommend you look at GoPower SW 2000 or 3000 watt unit.

Also I assume you have no load shed energy management that will shut down the A/C compressor when microwave or hair dryer is switched on for a few minutes. You have actually run these items at the same time to test right? Overload a few times to verify what loads work is not going to hurt the system.

You'll need two of either if you need 240 volt (or split 120)

Three rooftop ac is very ambitious

You've already got a pretty good sized generator with that 5,500. The hybrid function may not be worth much too you. If, for instance, you had a 2,000 watt gen and had an AC unit that ran at 1,500 watts but took 3,000 to start the hybrid would kick in briefly to let the little gen start the AC.
For your situation, yes, I guess you could use the hair dryer or MW with the 2 ACs going using the hybrid feature. Both of those appliances would be short duration use I would assume so they wouldn't deplete the battery bank too bad.
I agree, trying to use it to run 3 ACs at once is probably not a great idea. I don't know all the numbers on the ACs and your generator so it's hard to say. If the gen will carry all 3 but not start the 3rd when already running 2 it might work out.

“but all I really need is to run a hair dryer and microwave,“

Yeah, I can’t camp without my hair dryer and microwave too. Really.

Okay, I have only a 5500 Watt generator, it will run 2 a/c's and I can possibly run a 3rd a/c with the hybrid as long as I have the batteries charged but I am assuming the batteries will run down within a few hours so I don't think running a 3rd a/c would be a good option. From what your saying it will start the a/c but may not run the a/c for any length of time.

I'm really not looking at running the 3rd a/c with the Inverter but all I really need is to run a hair dryer and microwave, But not at the same time, and run my residential fridge full time tho.

So if I had the hybrid I could run the 2 a/c's off of the 5500 watt generator and run a hair dryer/microwave and the residential fridge with the Inverter? Is this correct?

Do the "Witch" units use magic? 😉

[Lwiddis]

Do you need 3000 watts of 120 volt power? Or even 2800?

Eight batteries at 65 pounds each is 520 pounds? That’s a load of batteries.

To get 3000 watts from 12 volt batteries you pull 250 amps.

Even eight batteries won’t supply that for long.
