Modified Sine wave converter for Dometic Brisk Air II???

[ohiobenz]

I am building an LMTV conversion and want to put a Dometic on the cab roof for AC.
The spec on the Dometic is 1725W 110VAC.
Will it run off a 3000W modified sine wave 24vdc-110VAC converter?? It won't be running any other 110vac appliances.
The cost is 1/2 of a pure sine wave converter....

Inverter.

And yes you need PS

For the Watts side, may need to add a slow start.

Better to forget running off batteries, use a nice quiet genny more practical.

Figure 50+AH storage per hour of time shifting, dedicated to that alone.

Reduced with tight thick insulation.

Still need a big genny, easier to run aircon off that.

I would go for a pure sine wave over a square wave, your equipment will thank you. Dont cheap out! Also check the specs if your 3000w is peak to peak or RMS if it is P-P its a 1000w inverter.

Magnum is the way to go for quality inverters.

Singlephase induction motors usually can run on ’modified sinewave’, but they are NOT happy doing so.
Dometic makes inverters what will power some their models of A/C. Those are claimed to be pure sinewave. One could safely assume dometic A/C appliances require good sinewave.

Btw, 1725 watts is about 75A at 24V. That makes for a big rack of batteries if its intended to run for a reasonable time without alternator or other charging.

This would only be running while driving. Meanwhile, the plan is for a Tesla house battery bank and about 1300W of solar panels. A system along the line of Mortonsonthemove setup: http://www.mortonsonthemove.com/toms-tech-stuff/solar-phase-2-the-tesla-battery

It sounds like a PS converter is the plan...

Your camper plans is similar to my goals. In addition though; I plan to connect mine to my house as well when I am home with it.... so home can benefit from the solar power instead of the panels sitting there doing nothing. I'll have 1000w of solar

Right, but I'm more building for off grid stand alone. It would take a much larger inverter, or a 120/240 generator if I wanted it to work as residential backup system....

Tesla won't warranty powerwall used in a mobile setting.

 

[ohiobenz]

Not using Powerwall...

What about this one?
