SRNE 12kW IP65 HES and 10kW ASP

I knew there were reasons I wanted the HESP instead of the ASP. I've just been waiting for them to be available on Amazon for so long now that I've forgotten all the details.

Thank you for the great summary.

All this is making me rethink, lol.

I don't care about grid feedback, but I keep going back and forth between the ASP and HESP. A pair of ASPs is so much less expensive. Once installed, I won't be looking at the screen. SA will do the config changes.

But, I'm a techie. I like stuff...and things.
:geek:

Why not a trio of ASPs and more batteries...

Be aware you can not adjust voltages in SA on the ASPs, only current and priority.

Its not hard to decide since the asp is so much cheaper.

Take the features that the asp can do. Find something you need it to do that it doesn't do.

See if the hesp can do that feature that you need that the asp can't do. If you do find something like that then you buy the hesp.
Otherwise you save a bundle of money and buy the asp.

Easy.

Agree. I think I'm going to try parallel ASPs with Solar Assistant to switch between UTI and SBU to get export + battery usage.

CTs (maybe using Emporia Vue) to help Solar Assistant decide whether to switch between UTI and SBU (if pulling from grid, SBU, otherwise UTI). Or maybe i can do it that with the info provided by inverters themselves to SA without CTs.
 
I am interested in the 12kW HESP's:
- for the expansion from 18kW to 24kW output of my system.
- for the reduced wall space two inverters will take instead of three
- for lower standby idle of these two compared to my current three
- for PV RSD feature I currently don't have.
- for PV Arc Fault detection feature I currently don't have.
- for the price point compared to other 12kW output inverters with the above features and 120/240 60hz output.

I was getting nuisance arc fault errors on my current setup such that I ended up disabling. My panels are on metal roof of non-dwelling structure so I was less worried. Maybe works better for most setups.

I have my panels on a metal roof of non-dwelling structure as well,
Technically the PV would need to be on a structure 'dedicated only for solar' (ie a ground mount) to be exempt from the RSD and AFDD requirements.
Do you suppose the metal roofing was causing the nuisance trip errors?

Does it have any levels of ARC fault sensitivity that can be adjusted, like the MidNite Solar Classics?

I think they do anyway, maybe they have sensitivity adjustment on ground faults.. not arc faults.

I couldn't figure it out. Was happening on different strings and different inverters. Fairly erratic.

9x450w so pretty high string voltage and 500ft distance inverters to panels, which might have contributed, honestly no idea

Don't know about HESP. I didn't see any options in manual.

My growatt min11400 did have some sensitivity adjustments but I didn't seriously explore
 
Can someone confirm that the HES models can operate without batteries and if there are any issues with this setup

It worked fine without battery for me.

Did we ever determine whether the HESP does AC coupling?
Click to expand...

Good question. Yet to be confirmed but my understanding is it can AC couple as a slave but not master. It will respond to frequency shift initiated by another inverter but it will not shift frequency to control another inverter. Below is the AC coupling settings page.

Funny thing, just finished my Borick order. I got 3 ASP 10ks. I can either use the 3rd in my pole barn or just have a spare.

3 of these shipped air freight DDP is about the same or slightly less than 2 of the SGP 10ks. Food for thought.

More planning and parts time!

Its not blue though so no go for me. Plus amazon has me covered :)

I was told the same by a seller who could not obtain the SRNE version for sale to USA for some reason

The spec sheet looks pretty identical, I'll attach the ASP.

This one has 18 months warranty instead of 24, I noticed that. Otherwise, looks pretty much the same.
