SRNE HESP48120U200-H

user2562 said:
Not to derail the thread, but if I exceed amp limit on this inverter how much risk am I taking. Additional panels I bought are Jinko 54HL4R-B. Isc 13.8A and at Imp 13.3A So two strings in parallel on a single MPPT exceeds 25A limit (27.6A Isc, 26.6A Imp). Not way over.

I'm not sure what in this type of an inverter would fail from overcurrent (it already should limit its output to 6000W per MPPT). Does having the additional current available somehow result in additional heat?

I wouldn't hesitate. I'm slightly over the 22A limit on my ASPs and ASF, I see frequent clipped but haven't had any issues..

That's seems like it would be the grid import limit,. I's nice it has an export limit as well, that could be useful for those with limits on old grid tie systems that want to add battery backup.

Agreed, it could be better.

The 'over/under' excited ones are the cases where I'm not strictly following what they mean.

I'm really close to pulling the trigger on a pair of these. I like the additional features, and I think for my particular use case, being able to blend power would be worthwhile. I've gone through the ASP doc -- I suspect because it's an 'offgrid' and not hybrid inverter, you're either supplying your loads in passthrough (grid), or on a combo of PV + battery. Perhaps I'm missing something / my understanding is completely wrong.

Then, on balance, with 2 HESP's (or ASP's), I don't think I'd really need grid to handle a load spike. But I do want to be able to charge from grid when it's cheap. Once I start my project, I won't initially have enough solar to do all the charging, though I think I could get pretty close to covering my daytime loads.

(Yes, I'm aware the implications of being grid-tied).

I'm not sure on the over / under either.
It would be a good way to test the technical support...

I think @Crowz can explain it better than I can, I believe it relates to setting 34; if you are running mix load it will use PV and grid to cover loads.
If you set it to on grid you can export and there is another menu option to adjust power exported.

You could take a double conversion route, go with the less expensive ASPs and use a rectifier to charge the batteries from the grid, you'll take a slight efficiency loss but be guaranteed to not export.

Its a full hybrid inverter if you set it to util on option one and mixed lod on option 34.
Click to expand...
But option 1 Util + 34 MIXLOD doesn't allow grid export, right? And 1 Util + 34 ONGRD doesn't let you use your batteries as first priority for loads instead of grid (batteries are just there for grid down)? Or is there a way to do grid only when insufficient PV and batteries out ?

I actually asked Borick this an hour ago as not sure I need anything from the HESP over ASP. Except this. HESP looks to very clearly have the ability to do this in manual.

Here's the explanation I got on over/under parameters:

Reactive power over/under excited is a very specialized technical parameter about on-grid. In order to maintain a good power factor and system stability, inverters are usually equipped with a reactive power compensation function. By dynamically adjusting the reactive power output, power factor optimization and voltage stability control can be achieved.
It is about the parameters of on-grid, which you don't consider for now if you don't sell electricity.
 
Hey guys. How are those of you who have bought this inverter liking it?

I've contacted Borick and it seems this inverter is certified for use in Japan. So it might be one of my only options.

Interested in opinions.

You are able to grid tie it and sell back power no problem with it as well, right?
 
I see a RSD mentioned brieftly on the Manual, anybody knows if this unit has Rapid Shut Down?
 
FYSA. I've been told by Borick on 9/21/24 when I asked again to make sure, that it's actually NOT CERTIFIED for grid-tie use here in Japan after all.

But they have all the marketing materials in Japanese and even sell it on Amazon Japan. So it's just for off-grid use it seems after all sadly.

Oh well... was hoping, but it didn't pan out.

These were the prices I was quoted on July 9th.

Two of the HESP48100U200-H Price:
Inverter: 1779usd/pcs
Air Freight (DDP): 909usd
Total Price: 1779*2+909=4467usd

Two of the HESP48120U200-H Price:
Inverter: 1849usd/pcs
Air Freight (DDP): 909usd
Total Price: 1849*2+909=4607usd

The time limit for DDP airfreight is 6-8 working days. The factory will usually ship within three days. If you need WiFi module, 25usd per piece.

@InTheHills
Inverter worling good ? can you post the link where you got the inverter ?

It doesn't seem like you can use the Generator input on HESP for AC coupling (would be nice to pair with an ASP). I'm making that assumption given breaker sizes don't allow for any more capacity than what inverter itself can produce.

still seems insane value for hybrid grid tie @ 48v. boat shipping ddp at 8 units is <$200, making the unit ~1900

@1201 or anyone with HESP :

NO AC coupling ability for HESP unit ?
