I did a little comparison a while back. (If you tap my name on the post it should take you back to the original post.

At first I thought it would just be the generator port and IP65 rating but it seems to be a whole lot more. RSD capability, remote CTs, etc... Yea the HESP might cause some waves in the market...
Attached a few screenshots I found interesting skimming the manual.

That's the price I was quoted from Borick. I'll update when I get a quote from SRNE store.

That's a great chart.

SRNE posted this video a while ago that shows specs for their offerings at that time.

Nice to hear it's working well, not many are running that model that I'm aware of.
Looking forward to more feedback.

Where did you order from and how long did it take?

If I were buying prebuilt batteries today from US stock I'd go with SOK through Current Connected due to a great track record, support and user serviceability. Otherwise I'd look at overseas vendors, SRNE makes a wall mount but I'm not sure on pricing. You could also check Docan and Gobel for prebuilt US stock and overseas. I've purchased cells from Docan a few times with good results.

I was talking to someone at CurrentConnected yesterday. Rackmount batteries are in short supply right now. Personally, I'd go for the Ruixus, but when you add in shipping + the hazmat tax, it really does boil down to where you invest your time.

I just did a Docan order. 66 EVE 280Ah Grade A cells (2 spares), 4 Apexium boxes (this is my time vs money saver, I don't want to build an enclosure, and I want the cells enclosed). Plus I'm fairly new, so the guidance on balance leads, etc. is worthwhile.
 
Received the SRNE ASP 10KW split phase inverter today. Similar box and packaging as the HESP 12KW I previously ordered. Box was scuffed up from shipping but the inverter is well protected inside the box (foam) and was pristine.

Also like the HESP the ASP appears well built, case is sturdy (powder coated steel, the HESP is powder coated AL). I opened the case and peeked inside; circuit boards, wiring, cables all look good, well marked, logically laid out.

After unboxing I hooked it up to a power supply for a quick test. Good display with lots of operating parameters displayed, the menus are fairly intuitive and settings were easy to adjust. I had it configured and operating in minutes.

In the box was parallel cables, battery lugs, mounting bolts, and wifi dongle.

All in all a positive initial impression. Time will tell how good it is, but like the HESP it appears to be a solid inverter and good value.

If this one test out, I am likely to order another to have a 20KW setup. I would consider doing a bulk order to save on shipping, message me if you have an interest.

Can I ask why did you go from HESP to ASP? Is this a different system?

Would you be able to post some pics of the ASP?

Different systems. With HESP I am adding additional PV & battery backup to an existing on grid system. ASP is for a separate off grid system.

How are you integrating existing grid tie system with hesp? Does it sense when your grid tie is expecting and divert that per to the battery?

Keeping the existing grid tie inverter and simply adding the HESP hybrid as a second inverter . Both back feed to grid, but only the HESP provides backup power during outages (12kw).

Can you elaborate on that?
I never had an issue powering my house when the grid was down and my ASF was connected to the grid and my ASPs have been powering the house with no grid connection just fine.
Now that I typed that I think you are referral to powering a panel on the input side by utilizing the CTs?
I must need sleep.

How would it provide power on the input side if the grid is down? Doesn't it look for a grid to sync with on that side? If it let you power that side when grid was down, you could zap linemen if you didn't manually flip a breaker.

That's my understanding. Could be done with a Transfer switch and some means to disconnect from mains. More straightforward is connect panel or sub panel on the output side and let the inverter do its thing
.

I'm not sure, I was tired and not making sense ... I doubt it would provide power, even with a CTs. It couldn't to be UL1741, correct?

For the HESP 12KW I just installed I am thinking of a single 280AH/ 15KwHr battery. Its a grid connected system so I really don't need days of storage.

Seems like the pre built 15kwHr batteries are all using 200A BMS, with maximum discharge current of 200A. The HESP can pull 230A continuous at full load (and surge to 280A). What's the solution? Build my own battery and use a 250A BMS or limit the max power that HESP could deliver?

Run more than one battery.

By running more than one battery the load is divided across them. I have 3 5kw batteries giving me 15kw in batteries. Each battery can handle 100amps continuous and 500amps max so your 230amp draw is actually only going to pull around 76amps on each battery of with a setup like mine.

76a/100ah battery
Vs 230a/280ah battery

Virtually no difference in charge or discharge rate lol

So I posted what I did. He said it would exceed the 200A bms so I pointed out he could use multiple batteries to get around it.
