Selecting a high wattage psw inverter

[pianotuna]

Hi,

I'm considering what to buy next to replace the existing inverter which failed yesterday. I need to have 2500 watts but 3000 would be better and it needs must be pure sine wave.

I'm looking for quality names. The three I am aware of are:

Magnum
Outback
Victron

Can anyone add to this list?

Found another inverter that appears to be a quality unit.

Power Master.

Hi BFL13,

Thanks.

Here is a tear down video about motomaster 3000 MSW

PT, if it fits your "work around" plans at all, this is an excellent 3000w MSW inverter. I have had one for a year now and it does everything. A camping neighbour has had his for three years now and also no problems. Not PSW but who cares?

It is on sale at Can Tire from 8-11 Sep this week for $180 🙂 AFAIK it is a Xantrex.

i just nuked some bacon and melted some butter on some Hawaiian bread
two different operations
bacon 2 strips 30 seconds, avg 1445w 114amps
bread 15 seconds
peak power 'observed' was 1556w

I sure like my Tripp-lite inverter. It may not be a PSW but I can't tell it with anything I use it with like my old MSW inverter. No problems starting the little A/C or a microwave pulling 1375w.

24v still affords you a work around, it just adds another 20 minutes to rewire the battery bank in a similar situation.

I'm running 48v, but I still carry my old 12 and 24v inverters. A bit of rewiring and I'm bib. I'd have to reconnect the solar controller to sense voltage and disonnect my 48v charger.

I wouldn't be doing any heavy-duty stuff like running air, or even MW for too long on 12v. I don't carry thumb-sized wire anymore.

Hi Smk,

Yes, I've thought about 24 and 48 volts.

If I do that I loose any redundancy. Because I stayed with 12 volt when I had a problem, I had a work around in 20 seconds. If I had gone to 24 volt I would have been up the creek without a paddle.

If I were starting over from scratch I'd lean towards 48.

But recent events seem to indicate I should stay with 12 volts.

Have you considered going 24 volts for this service? IMO over 2000 watts is really pushing 12v system a bit hard.

Tripp Lite in the working industry was a good known working source but in the RV world I really have not heard of many if any using them... Of course most of my working years was involved with 19-inch rack mounted shore base systems...

The line I hear about the most in the RV world is the MAGNUM line... I did read your recent posts of a couple of short comings with Magnums.

Building homes for Solar Power the 24-48VDC items really become the way to go...

I like the DECK MOUNT idea big time...

Since I am getting up in years now I really want to develop a 3KW Power Bank just outside my Operations room here in my house to run all of my Radio and Computer toys...

Having 400-500Ahs of Battery capacity on my OFF-ROAD POPUP trailer should be all I need for the near future of RV off-road outings.. Really have not done much of getting OFF-ROAD the past two years but things are starting to look up. Time to get back out there again and enjoy some more waking up on a creekside morning somewhere while I still can...

I know - This is not much offered help for your questions haha...

The vast majority of ex-Trace engineers migrated and formed Outback. If I had the money it would be applied there. The 1st order of the day is contact their Tech and get an opinion about inverter to inverter coupling.

[time2roll]

With no monster inverter you do not need much 12v. PD, solar and a single battery would get you through. I assume you would still have a 12v support system. You are back on dry land, no paddle sure but no creek either.

If you add a second solar array it could be at the higher voltage.

Just some random ideas as you start the next journey 😉

Hi MrWizard,

Yes it does interest me. Ty.

Hi dons2346,

I have not given up, or Magnum would not be on the list. I'm just curious as to what options may be.

I also purchased from Imarine.

Don, I think you are giving up on the Magnum to fast. I think they have the best support in the industry plus they speak English. Catastrophic failures can happen with anything so good factory assistance is important

I really like my 3000 hybrid. The cheapest place to buy any converter is from http://www.imarineusa.com/ The cost of the hybrid 3000 is a little under $1700
