F49 Fault on Schneider XW6848

[wheisenburg]

I am having two issues with my Schneider that started a few months ago. One is that I am getting Overvoltage F49 faults and sometimes under voltage faults. I have a dual inverter setup, with three Orient Power wall mounted batteries. The faults always seem to be on the same inverter (inverter 1). When I look at my traces, there is another issue. Sometimes the SOC reading is dropping to 0% (no the batteries are not dead). It will stay there for a day or so and then come back up. Also, the DC voltage and current traces, seem to have random glitches even when the inverter is not running a charge cycle. The way I have it setup, the inverters top the batteries off about every three days. I tried at one point to use SOC to charge the batteries. It did not work well. The SOC reported to the inverters would be at 90 even though the batteries were nearly dead. I am using voltage driven charging now.

If I disconnect my main power, the inverters will kick in and run my house with no issues. The problem seems to only occur when in standby mode. It happens once or twice a month. Maybe I have a bad connection between my main DC bus bar in the Power Distribution Panel and the inverter. I am thinking I should put the system in bypass mode shut all the batteries down. Then clean and re-torque all the DC connections to the two inverters.

I am also wondering if the Insight Controller or the communication link to the batteries might be bad. It seems to work fine most of the time, but these F49 faults seem to happen when the SOC is now being read properly.

Any other ideas?

Hi @wheisenburg : I had this problem with the latest 1.18 B41 software for the Insight home when I tried to use the new MPPT parameter input function. It was explained to me here in this thread that the HBCO sometimes activates 3V less that the value set in the Insight. What I did was to raise my HBCO and go back to the charge controllers doing their own thing with the settings built in..

Schneider Insight 2.18 bn41 - anyone install the upgrade?

Hi, I am wondering if anyone has installed the update (1.18 bn41) to Insight Home/Facility. I downloaded it and I see that it was dated July 23, but I think this is the date of the first 1.18 update that they pulled. It reappeared a few days ago, but there was no notice posted anywhere about...

Hi everyone,

I have an issue with the Schneider XW Pro. I got F49 error. How can I clear the fault? Is there any manual how to do it remotely via insightcloud?

Ouch, overvoltage shutdown.
F49 is usually just a warning and won't shut it down. I didn't realize the shutdown version was he same code as the warning.

Your high battery cut out is set to 60 volts. That should be hard to hit as that is 3.75 volts/cell

Is the inverter operating? Do you know why this alarm set?

To clear faults, alarms, whatever:
Click on the device (XW), go to configuration, under controls, use the drop down menu for "clear" to choose what you want to clear: faults, alarms, etc.
That's on the local application, the cloud version should be similar.

I went through the system and retorqued all the DC connections. I also all checked the info in the batteries BMS. On my master battery it showed a bunch of over voltage faults in the BMS and two adjacent cells were reporting some out of balance voltage readings. One was really high and the other was really low. So I discharged the system to 75% and then recharged it after backing the charge voltage off a little. All the cells in all the batteries are now back in balance.

My system is AC coupled only and the batteries essentially only function as a giant UPS.

So far so good. I am going to look into a possible firmware upgrade.

Thanks.

Thank you for the information.
I've adjusted the HBCO and reset the fault.
I appreciate your help!
