Its not too loud just running without a load in my office right now sounds like a small fan. With load is prob another story tho

When charging, they're really loud. Not bad at 20-30% load only (not charging). Haven't pushed them much harder as of yet, but I'm guessing the fans will also ramp up at higher load amounts.
I also have a submersible 1 hp well pump at 550 feet. There is no controller for it just a 30 amp breaker going to 10 ga wire buried to the well. How would a soft start be connected in this case?. What are you looking at in soft start models?. Thanks.

Single phase well pump without a controller to provide a 3rd phase start? Pretty rare.
Before you start adding a soft start, I'd look into the pump model and make and determine if there isn't a capacitor at the pump or it isn't one of the newer inverter internally controlled pumps.

My 1hp is down around 350', attached are my inrush readings.
Based on the research I've done, you can't add a soft start to a 2 wire pump.
I wonder if you could add a capacitor(s) to the inverter output to help buffer surge...

After looking into it a bit and having a submersible that is nearly 20 years old, I'm thinking of going with a new soft start Grundfos pumps.
Do you think two of these inverters can handle that inrush current?.

There is another user floating around here (had a really nice build) that said 2 handles his no problem, along with other items running.
In theory they should, 38a x 120v = 4560w.
They claim to have a transformer, which I assume helps handle the surge.
There is a big part of me that is leaning towards the 6048 for the large transformer and much longer surge duration. 1 also provides split phase and you can parallel them.
These appear to be a beefed up 6548, I've done a fair amount of searching for them to handle a well pump and didn't find much.
Edit
Here is the link @Kluoco did you happen to measure the inrush current of your pump? https://diysolarforum.com/threads/eg4-6500-ex-inverter-setup-issues.41574/#post-526553
Thanks for the link. He says if I read it correctly, that his well pump pulls 1500 watts per leg which is not much at all. May not be a deep well like ours. The main reason for me is to power my deep well and I can't find any examples yet of these inverters powering a 1-1.5 hp submersible pump other than yours. I also looked at the lvx6048 for a long time and for some reason just bought two of the EG 4's. But the math says they should power the well. I may have to buy a good meter and measure the inrush current on mine. I do remember that it kicked my 10K propane generators butt when it cycled on during the last power outage but the generator ran it.

Since these are basically 6548 units, can you parallel 2 of these to 2 existing MPP LV6548 units ? Or is the firmware different?

My understanding is the firmware is different. So it wont work.

Yeah, I saw an answer from SS buried on one of the 27 pages of this forum at 2am last night saying the same thing.

I will be in a couple of weeks - my pump is 240v@20A. Ran my entire shop all day today including a Frigidaire 25,000 btu ac unit Entirely on PV. Both units hummed right along at 16% & 30% capacity. A slight flicker on all my overhead LED lights when the compressor kicked on, but not every time. I don't forsee any issues with the well pump. I'll try it with the start/run cap that's already on it. I will measure peak current draw on startup before I switch over just to be sure.

The Fluke meters are my go to for clamp & multimeters. Got my first one in electrical engineering school 40 odd years ago. They're pricy tho. Will has one in his website he recommends

Any multimeter with a an amp clamp will suffice
Edit: With dc clamp meter 6000 counts

Thanks for the input. I will buy that one. I see you have your panels already I have 12 250 watt and went to but 20 more and the shipping alone was 700 dollars. This is not acceptable.The Fluke meters are my go to for clamp & multimeters. Got my first one in electrical engineering school 40 odd years ago. They're pricy tho.

Somting Wong with that price... I bought a pallet of 27 gigantic panels from Ian @watts247.com and shipping was $376, Las Vegas to Idaho.
And fwiw, not all "multimeters with an amp clamp" support measuring DC current. Buyer beware. Look at the specs closely. The vast majority of them only support measuring AC current. In SolarLand, measuring DC current is a must for your battery packs, Solar inputs, etc.

Looks like you chose terminal pickup - which is significantly less expensive most of the time.

I was pleasantly surprised with the quality of Amazon commercial I picked up. Wonder who the oem is...

Thanks, I'll look tonight.
It's robbery to charge 700 bucks for shipping. Most people will just stop buying until the sellers find a way to help out their buyers on this.

Ya, Signature Solar loses a significant amount of money on shipping as more often than not the final total is more than what they quote the customer. They offer store pickup if you want to save the $700 that shipping companies charge. Personally, the cost of renting a truck or the gas of using one and my time would be worth more to me than shipping costs.
