Good 3000 watt Inverter Brand?

Looking for opinions on better 12VDC, 2k or 3k inverters. Don't need charging capability.
Don't recognize any of the market's offerings these days.
Want to run a 120Vac (about 10A running, 20A start) well pump off the inverter in emergencies.
Long story short, also working with a wind generator and maybe 2k solar.
The plan is to install the inverter in our toy hauler, but connect to permanent outside DC charging sources when stored.
A steam engine would cool, but definitely not simple.
Thanks!

I have a Nature Power "pure sine wave" 2000W. Got it on Home Depot online. Seems pretty well built and no problems with it so far, although full disclosure my use has been pretty minimal so far.

I've been looking for awhile at inverters. (2yrs)
And I keep coming back to this brand. Giandel.

https://a.co/4YoQTk2

I haven't bought one yet. But 90% sure this is the one I'll buy for my solar generator project.

I have a Giandel 2200 watt inverter that I've run my 13.5k btu AC unit and microwave, not at the same time, without issues. No problems with any sensitive electronics either.

Thanks much!
Looked at Nature units. Seem good.
The Giandel is unfamiliar, but the 2200 continuous (?) might work well.
Off to have a look.
Thanks again!

I would look seriously at a Renogy 3,000 w Pure Sine Wave Inverter.https://smile.amazon.com/dp/B096MKPQ...xpY2s9dHJ1ZQ==




I like the form factor as it mounts easily on a vertical surface and as it's height/thickness is less than many it allows for more flexibility in locations.

I have a 2,000 watt unit and it's worked flawlessly since I installed it over a year ago. I use it A LOT. I have mine "hard wired" and don't use the outlets.

Less than $400 on Amazon.

Inverters seem to only supply 50% of their advertised wattage for more than a few minutes meaning if you need 2000 watts you should get a 4000w inverter. And a shed full of batteries if you need 2000w for any more than a few minutes.

You'll probably find useful information in an "off grid" housing website where folks run whole houses off batteries -- sheds full of batteries.

I'd say that really depends on the inverter. There are definitely low end ones that don't do 100% duty cycle at full load, but a good inverter should be able to deliver it's rated continuous wattage capacity basically forever as long as it's in the proper environment.

My Renogy 2 Kw will run a full 2,000 watts until battery voltage drops to shutoff. PEAK rating is 4,000 watts for around 30 seconds so starting something like an A/C compressor doesn't shut it down.

One should make sure they are reading continuous load ratings rather than peak.

Also, I would avoid the cheaper MSW ( Modified Sine Wave) Inverters. TSW's are very affordable today and anythjng you plug in with a transformer or motor will thank you.

I would watch this video about this no name inverter. At about 23min. He does a comparison to the Renogy.

https://youtu.be/I5rBVGSszBY

The comparison shows the Renogy has its own short cummins.

Since I am experiencing none of the issues he showed with the Renogy I'd say he has a defective one.

Stop by the DIYsolar forums. They have a lot of folks doing exactly what you are.

Thanks for all the input!
The Renogy 3000 looks like the winner. The Nature units will not "peak" beyond .05 seconds. So what they set as the output is what it is.
I have a real narrow focus and understand that this setup will not power more than about 2-3 k watts and the closer to <2k the better.
Only want capacity to operate an 8Amp 110Vac submersible well, a radio shack, and 2 home refrigerators. The well can be managed.
And, we are adding a 110Vac fridge to the toy hauler, which is where the inverter will be mounted. Toy hauler is stored about 20' from the well, and I have a huge roll of 10/3 that I use to run generators to the house when power is out. Winter ice is our only major power issue. But it is an issue. Blackouts are a minor concern--for now.
Seriously considering a pallet of the Canadian take out solar panels. Not trying to grid tie or any such thing. Completing a wind turbine. Once that's operational on two 8d's, we'll sort the rest out.
Thanks!

Renogy has a Ebay store. They have open box or returned inverters.
I purchased my 3000 watt inverter from them last year. The only issue was one of the lugs bent. I straightened it back out and it has worked flawlessly.

I was able to save $100 on it.

I just looked on E-bay at 3,000 w Renogy "Open Box" Inverter. They wanted $549 and Amazon was selling same for $363 only New In Box.

Perhaps the year made a difference

I just checked and only paid $299 for mine on March 29, 2021.
I guess we can blame Covid

I put in the Renogy 3000w inverter and one of their ďsmartĒ batteries to run my Keurig coffee maker, Iíll eventually replace my house batteries with LiFe when these AGMís expire and connect the inverter to the main batteries.
