Mean Well inverters?

Has anyone used these Meanwell inverters in their builds or heard/seen them used in other industrial or commercial applications? Meanwell makes good quality components but I am wondering about their longevity especially in mobile systems.

NTS-3200 spec (24V $913.56)
or
NTU-3200 spec (24V $872.59) - basically a NTS-3200 with AC bypass provided by offshore power.

Thanks

Mean Well is very high quality imo, if they ever made a large 48v inverter I would be very interested.

I am using their 2300W power supply as my grid charger.

That model looks very camper focused but sounds like that's what you're doing?

Avoid putting 12v lithium batteries in series to make 24v if you can. Use 24v batteries.

Yes, I am building a 24V battery out of individual cells.

I've heard these are used commercially in the US but it seems not so much in the DIY space, unlike their PSUs and battery chargers (RSPs).

Since I will be boon-docking and traveling internationally, I'd like to having separate units. In case one fails, I still have a functional system. I am thinking of getting:

• two NTU-3200-124TB:
  • 2 x 3000W continuous rated power
  • 90% efficiency
  • 100-120VAC AC bypass (for the rare scenario, if I already paid for camping at a campground in North/South American countries that are on 120VAC )
• one NPB-1700-24 one RSP-1500-24
  • 90 - 264VAC charger input, 50A (in the rare case I need to charge the batteries, worldwide input VAC, planning a 4-5kW PV array, 23kWh battery)

... instead of:

• one Victron Quattro 24/5000/120-100/100
• 1x4000W,
• 94% efficiency
• 90-140 VAC charger input, 2x100A

Price-wise (not the most important factor), without tax, Mean Well is cheaper.
Mean Well: $2,178 (2 inverters + charger)
Victron: $2,900 (including the PC dongle)

edit: changed RSP-1500-24 to NPB-1700-24 thanks @hwy17

What about an NPB-1700-24 instead of the RSP-1500-24?

Wow! Thank you for making this post. I didn't know Mean Well made inverters. Been using their switching supplies for 15 years with no complaints others than some are noisier RFI wise than others. Good prices on those inverters too. Very tempted!

That's probably a better choice since it's designed for batteries, thanks for the suggestion!

So what are your 24v and 48v considerations? It looks like Mean Well offers both the charger and inverter in both voltages.

Is 8 280Ah size cells the right fit for physical space and likely all the capacity you'll ever need?

I used the Energy Audit tool to get to an idea of the ideal battery and PV array size.

It's 24V because I will be using the Electrodacus SBMS0 and a lot of my appliances will be "native" 24V.
The battery is a 24 cell, 304Ah, in 8s3p configuration. I am still identifying and searching for the right PV panel but I will have space for 12 panels.

Good day,
I run a older model TS 3000 true sinewave inverter from Meanwell 24/7 now for about 5 years straight.
it powers my house, and have never been switched off in the last 5 years.
I run pumps, my welder, basically everything from it, and it has never missed a beat.

I used to service and upgrade UPS'es to lithium batteries for a couple of years and have seen many UPS'es on the inside from small to big, cheap to expensive and I can tell you with all honesty and certainty that Meanwell's build quality and component's are the very best in the industry.

The longevity of Meanwell inverters is amongst the very best brands in the world, if not better.

My inverter was second hand when I got it, so I do not know the true age of the unit.

I just found this and I didn't know Mean well made inverters as well, but it kind of makes sense.
I think they are fairly priced among the "quality" inverters, but they are still expensive compared to Chinese once.

I first considered Victron but apart from the price they are very big and heavy from 3000VA upwards.
Then I found the good review of the FCHAO 3000W on Andy's garage youtube channel and was considering that mainly to save a lot of weight.
Of course I know I can't compare the quality, but i really can't understand why with inverters you get really expensive or really cheap chinese and nothing in between. Like 1000 euro from reputable brands or 200 euro from china, the 5x difference is crazy.

If the mean well was like 500 euro I would get it without thinking, but the cheapest I found on sale is 900 euro. The saving by going with the FCHAO is very tempting. I know I would have to consider a derating, that's why I'm considering the 3000W for a max draw of 2000W, I would use a shelly PM on the inverter output to cut off on the occasion of overdraw of say 2300W for safety.

Just sharing my thoughts...

I thought MeanWell was an Asian company. It has a super East Asian English name vibe (Chinese to English literal or phonetic mashup (it’s literal in this case))

Google… yep, it is Taiwanese.

Yes, still from Asia, but I was comparing it to all the other cheap interters, like FCHAO that usually come from china. Not that everything from china is cheap, but you get my point.
