Selecting a high wattage psw inverter

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

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?

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.

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 ;)
