6 MWh SRNE ASF48100U200-H 10kw.

Thanks. I'll be taking it offline to swap the batteries to the new rack so I can verify then. (I think I said that last week...)

Unit off, no wires connected to ac input or outputs. Continuity test should read no continuity if unit does not bond N-G.

 

[Zwy]

this is the issue. lots of variables here. but as i said, someone mentioned earlier that it may switch when in battery only mode. 11v between N and G means something is going on somewhere

Unit off, any relay should show N-G bond. It takes power to hold a relay open so default is bond N-G without using battery power.

 

[Zwy]

The bonding relay can be controlled through the settings menu. That can be confirmed with a continuity test of AC output on the inverter while disconnected.

It appears they did address this in the manual, a very positive sign from the manufacturer.

Good news on the N-G bond
.
I just got my all in price directly from Ella @ SRNE.
$1382 USD all in with DDP shipping and wifi dongle. Not that I think I will nee the dongle as I use solar assistant.

There is one section on N G bonding in the manual, I'll check what option I have selected tomorrow.

looks like problem solved. i was just told my alibaba inverter is going to be shipped today, except that it looks like this. hopefully it'll work fine

I won't get the testing today. Started an 11hr 3 part print for a work friend when I got home...

What model was listed on your invoice?
Do you have a link for what you ordered?

its the ASF48100U200-H but made by a company called JHOTA.

Looks similar to the EASUN ASF48100U200-H version as well.

 

[BuffaloTrace]

I always liked the growatt 5k inverter but obviously that's for the Euro market. I'm glad they adapted that idea for US market with the same specs at a comparable price point.

Interesting. Be sure to post pictures when you receive it. I hope it works out.

Thanks for all your help and the kind words. I'll be sure to let you know how it goes

So I am getting the stuff I need to hook this beast up, the manual states 3awg for the AC in and out (I'm running 120 only) would this cable work from the AC out to the breaker panel and from the generator to the inverter?

I don't think there is any chance 3awg will fit. I'd double check the manual.

 

[Herculezz]

Ya I did it shows for the neutral line 3awg, and 6awg for the L1 and L2 which is combined in single phase.

 

[42OhmsPA]

I really don't think 3awg will fit in any of them and 4 would be tight. I hope the manual is correct and I'm wrong.

 

[42OhmsPA]

Learning / dumb? time...
What's the correct way to install the Midnite studded breakers? Washer or no washer on the bottom. My thinking is the washer makes most sense but everything I've read here says no washers between to keep resistance down.... In this case I don't think it matters since there is another nut and washer anyway...
@Mattb4 did you hook yours up yet?

 

[Herculezz]

My guess your correct, because the manual recommends the use of ferrule ends which crimps on 3awg wire but the end is less in diameter, because it's solid metal, but even so I don't understand them recommending 6 and 3 awg wire when the wire from the same terminal to the inner workings of the inverter are 10awg, lol wtf ;P anyways what are you using for each N L1 and L2?

Yea, I didn't understand that either.

6AWG THHN.
I ordered this since it was the best price I could find at the time, note that I didn't get the white; 2 blacks, 1 red, 1 green. The description is also wrong, definitely 15' not "... It was UL listed quality wire.

Updates.
I haven't forgotten about the N/G bond tests and other items mentioned a page or so ago. Work life and life hasn't let me take the house loads offline to test yet.

I'm slowly closing in on 1Mw with 0 issues.

I figured out what the root cause was of the random restarts a few weeks / pages ago... When some brilliant person was setting up the BMS's way back when they set max charge current at 60a per pack... I realized this while I was programming the 3rd BMS. They have since been changed to 110a, just under 0.5c, and I've had no issues since.... User error strikes again...

Hi, can you post your settings on the inverter...

How's this? (attached). Display screen bottom right is software version. Let me know if you can't read any of my chicken scratch and I'll try to decipher.

Edit - rotated that sideways photo. Drives me crazy when people post them sideways ?.

Thanks , all good... got a general idea... wanted to see your battery settings more than anything...

I think you covered the n/g option. have you ever investigated your current on ground issue? Thanks for posting the settings. seems pretty straightforward. Just curious, what are your battery and pv kw?

I never did clamp the ground or figure that out. Thanks for the reminder.
