I went with SRNE ASP-10kW looked like best bang for my buck. The advertising says the SRNE ASP-10kW is UL1741

Since it was brought up earlier:

I’d like someone to see if parameter #34 does anything on the “ac in” side as in check it for an ac output with excess pv applied . Hmmmm if nothing comes out means it is working as designed or anti-island is in there minus advertised ratings IEEE 1547.1- Ul1741sa - sb. Next hook up ac and see if your power meter spins backwards hahahaha better not…but….hmmmm

Edit added I don’t want grid tie. Not for me.

Actually the weight is pretty interesting. In any electronics in the "power conversion related" weight is generally a major indicator on quality... Though you have to know what has the weight, assuming it's actual components and not a brick inside of it or something lol

e.g. Computer power supplies are 95% of the time superior if they're heavier (at the same size).

What are the actual weight differences internally is what we'd need to know. Because including the case and all that is pretty irrelevant.

Kind of example of my thoughts:

Without breakers ~ 33 pounds
bigbattery.com

LUXPOWER 6KW Split Phase Inverter

LUXPOWER 6KW Split Phase Inverter
bigbattery.com bigbattery.com

With breakers ~53 pounds ~$200 + price difference. ~ 20 pound weight diff from breakers

However if we get down to it if weight was only concern we’d all be running low freq inverters. Victrons and such…heavy. My icon transformer.

The IP casing are heavy too. Add breakers …. So on. If stripped guts out weighed them vs other inverter guts then might have better idea. More built in mppt 2 vs 4 changes weight too.


The fronius is lightweight. …….Anyone that makes great welders with inverters knows a thing or three.
 
Update on my journey:

I found three Deye US variant inverter sellers on Alibaba. One told me they were out of stock. Another told me Sol-Ark has the exclusivity for Canada, USA, and Mexico. The third one, Hangzhou Seetek, claimed to have it in a US warehouse, and they quoted the 10kw version at US$2650 including shipping to Mexico and DDP. Not bad.

Then I searched again for the SRNE HESP and SEI inverters. This time I found Borick and other four sellers. Seemed strange they weren't as expensive as before. Turns out, it's the end of the month and employees were trying to hit their monthly sales targets. Haggle time, as @D71 said. Purchased the SEI-10K-UP inverter from Seetek at US$1950 including shipping to Mexico by sea from China and DDP. Let's see if I get it in good condition in a month or if I got too cheap/greedy and should have bought it from Borick for 200 bucks more without DDP.

And since I didn't see the User's Guide for the SEI-8/10/12K-UP in this thread (only for the European variant) and it isn't available in SRNE's website and the seller sent it my way, here it is, attached to this post.

It's very similar, maybe the same, as HESP's. SEI's AC voltage can be configured to 127V per phase, just like HESP, which will be useful in my case.

Seetek recently told me same to USA. After bought my SRNE ASP-10kW

Look out for the sol-ark police better hurry
 
EG4 18Kpv - 121 lbs
EG4 12kPV - 110 lbs
SRNE 10Kw ASP- 59.52 lbs
NDX 10Kw- 90.38 lbs

Why the difference? All but the SRNE have a big heat sink on the backside and a big breaker box on the bottom.

Add a few pounds here and a few pounds there, next thing you know it is heavy.

I'll have to weigh an ASP, sure seems to be a heavy for 59.52 lbs.

ASP weighs a heck of allot more than 60 lbs. Felt more like 100 lbs putting it on the wall.

I know the tp6048 weighs 100 lbs and they felt the same weight wise.

naw that we know are better performance, but they're "unnecessarily better" the price doesn't match the performance. You can buy $10 power cords or $1000 isolated power cords too.
"we'd all be running ____" just because it is heavy makes no sense, people have a budget and pick what makes sense with what they have

crazy the 12k and 18k are so close lol, are they the same exact case?

It weighs right in at 59 to 60 lbs. I just weighed one.

I buy based upon expected value. Take the price paid for these SRNE, I could buy 3 and still be below the price of the EG4 12kPV.

That means if the units last 5 years, the EG4 has to last 15 years. By then tech will have increased once again and really, in 5 years I might yank these off to upgrade.

Probably with the extra 40 lbs of breakers, relays and switches. A 200A pass thru requires some heft on the switch.
 
Usually there is a significant weight different between LF and HF inverters due to LF inverter having a large transformer on the output.
Toroidal transformers are often smaller and less weight that a standard iron core transformer.

So does the light weight inverter have a transformer? and if so what kind. Or maybe it's an HF that is mislabled

SRNE is HF.

I currently have a MPP Solar 3048 setup as Emergency power. I have ordered a SRNE ASP-10kW because want to have UL1741 and substantially more power output then the MPP 3048. Another Advantage is Split phase output for the SRNE ASP-10kW vs my smaller 3048 inverter.

I doubt ZWY can answer your question because think he is like us for them just looking at specs listed online.


You were previously shown the exact same inverters from LuxPower Tek their 6000xp and their EG4 6000xp with breakers for weight difference being the breakers. There is $200 price difference of more cost for breakers with eg4 version of 6000xp too.

What are you running? Are you considering a SRNE. it was obviously good enough for other RELABELS even Midnite Solar used a different smaller model for DIY until they developed new inverters. Are you needing help to make a purchase decision? You’ve been in this post since page 1 and we are on page 31 now…..? I think everyone in post is DIY ….No?

yep, I can't recommend any of the expensive ones unless someone just has a bunch of extra money and isn't interested in learning how to look at anything ever.

All of these are HF
