Hello all, need some help with settings of the setup that was left in a mess by a so called reputable company in Italy and they just walked away left it in dangerous way which I got local electrician to fix and make safe.

The next thing I have been trying to configure the settings but I am struggling with this as I don't fully understand it. SRNE support are in contact but slow and not really helpful.

The config is 6x330w panels in 1 string. 8x 12v100ah lifepo4 batteries in series and parrellel so 48v200ah.

The inverter appears to be working during the day but then late evening switches to Grid Mode and I have to reset to move back to SBU mode.

I think the settings are out which is causing the issues.

Thanks in advance for any help.
 
If you post all of your current settings it would very helpful so you can get good advice.

An important question, how do you know your 12V batteries are all evenly balanced?
Are they designed to work in series?
It's typically not advised to run 12V in series due to balancing issues.

Manual.

I'll check back after these super productive meetings...

Welcome to the forum.
 
Thanks so the settings are :
01 - SBU
02 - 50.0
03 - UPS
04 - 49.2
05 - 56.0
06 - oSo
07 - 60
08 - USE
09 - 57.6
10 - 120
11 - 56.0
12 - 42.0
13 - 5
14 - 48.8
15 - 40.0
16 - DIS
17 - 56.8
18 - 90
19 - 240
20 - 120
21 - DIS
22 - DIS
23 > 27 - ENA
28 - 60
29 - ENA
30 - 1
35 - 52.8
37 52.8
38 - 230

There was something about setting 04 and 14.

As said they were a recommended company in Italy and as it is off-grid they setup the batteries this way. I did disconnect and charge each battery to 100% before connecting them all again but that was about 4 weeks ago so I may do this again and get a voltmeter to test. I have just had the victron smartshunt installed by the local electrician who was doing some other work on the house fit as it needed a new lug!

04 is battery to Utility voltage, you could bump it down to 48V if you don't want to keep much of a battery reserve. 49.2V is already pretty low.
I would reduce 05 to 52V-53V at 56V its charging the battery full before switching back off utility.
I would reduced 09 to 56V - 55.2V
I would reduce 11 to 54.4V
14 down below around what you set 04 to.
I'd increase 15 to 44V to leave a buffer before they are completely dead.
I'd increase 37 to 53.4V or above so it will start recharging sooner.

The shunt will be an extremely valuable tool, assuming it's setup correctly, in determining your SOC.

I'm extremely happy with my SRNEs, as you are finding out there was a slight learning curve with the settings.

Good luck, post back when you have more questions.

He showed you his now show him your settings. It might help all future SRNE’ers like me. Give please. 😁

The shunt to be accurate needs to see cycles and current flow for the estimated SOC. It drifts with time even Victron states as much if idle. It is a tool. Like most things with solar it has quirks.

42OhmsPA is my most noted experience on here with SRNE - some others to but keep him in check for questions. There are several other inverters same as SRNE just relabels like SunGold Power and PowMr brands for instance.

Poster Crowz and several others…
Check this post various srne talk. Might want to ask questions in it too. Help everyone as well as yourself. Good Luck.

I don't have the same inverter and the menu settings aren't the same so I don't want to add confusion.

Right you are I glanced thought it was 8000 which figured was about same I assumed it was UL since “electrician installed.”

I stand corrected. 😁 i still want your settings. 😁 message them if you don’t mind. Mine is still in shipment. He is still welcome post in that srne forum post. Be nice to have branded forums under a tab. Easier then searching. 😁
 
I made the changes which seems to be working ok. The inverter switches to Grid Mode when solar is gone and batteries around 10% SOC 49.9v. Now it's on Grid Mode and powering the house and the batteries also appear to be getting a charge and now heading back upwards now reporting 42% SOC 52.1v. My understanding is that it should switch batch to Solar/Battery but not and only when I restart the inverter using the on/off switch. Thoughts and advice again greatly appreciated.

Try reducing setting 05 further, what is it set to currently?
 
So settings now are:
04 - 50.0
05 - 53.6
09 - 58.2
12 - 42.0
14 - 49.2
15 - 40.0
17 - 56.8
35 - 52.8
37 - 53.2 (highest setting)
Will see how it performs tonight.

Why are you charging at such a high voltage with setting 09?
05 also seems high. Did you see post 4 of this thread?

To increase 37 higher you need to increase 11 then set 37, after that you can decrease 11 again.
 
I did go through and change them based on the posts and I did notice that it maybe my fingers didn't enter the correct button. Let me go and make a change to them now whilst I can before the wife and mother start burning into the power!
