Hi guys, i have a system with a 5kW Synapse and 2 3000C Pylontech batteries. Everything been working fine for years, but this morning the area went out, and I think the batteries eventually both died. At the moment now I have the master that is charging, but constant red light, and the slave off. I have attempted restarting them, but no luck. Any ideas? EDIT: Master shows SysError

@ebrsa thanks, I have just emailed them. Hoping to get a test license for a week or so to see if it solves any of my issues before I buy it.

Nice, so where do I get it? Website?

@ebrsathe Centurion solar icc has a nice ability / tab for pylontechs, using the charge from the bmv as well. Axperts suck at guessing the SoC, does Manie's one have that?

@ebrsa I got the one from Centurion solar. Version 2.8.5. Is there another one? Sorry I'm still new to solar. Which is the best one?

I got it directly from Centurion solar, so I'm guessing it's an upgrade from the original. I notice a restart every now and again does help, but that's annoying.

I'm having the same issues. My ICC hangs continuously, where it becomes effectively unusable. Even something as simple as trying to see if there are updates becomes futile. I then close it, click close on the error message, and then wait 10 minutes for it to restart, before repeating the futile exercise again. The rest of my pi seems fine

Hi All, I know this has been discussed to death, but I just noticed my pylontech 3000c went to grid at 35.5V. I remember seeing @Coulombmentioning it should be at 48v.i set my icc to 10% back to grid. My night-time use is 400w,so it seems the inverter is overriding the icc. Should I change the to grid voltage to very low perhaps, to make sure the icc manages the crossover to grid instead? Thanks

Hey guys, So it turned out to be the MPPT, i replaced it and all seems fine. One more question... I have an Axpert King and 2x3000c batteries. I got the cable from Centurion Solar as well, but I see a fluctuating difference between battery discharge and load of up to 100W. What can cause this? See attached.

Thanks for that @Proxicon, do you perhaps have the file or a link to it?

U1 71.93 U2 02.40 At this moment my PV voltage is 0. It is stupidly hot in Durban today, and cloudless, if that is of any consequence Also, my load was about 400W maximum

Just to add. I have 2x pylontech 3000c batteries. They were put in a few days ago. Could it be that the BMS from the pylontech is causing this? Never had this issue with my previous batteries. I noticed mentioned something about firmware?@Coulomb

Hi guys, so all was running fine until about an hour ago. I noticed my electricity tripped, then went to the inverter. (Axpert King), and see that its lost PV. Any suggestions? See attached.

Ah ok.... So would it then just be a matter of setting 5% on the ICC as a back to grid?

Hey guys, I went through the forum, and see the suggested back to utility setting is 48V. I have 2x 3000c's, my question is, with them able to go down to 5% SoC, what percentage is 48V? I should be getting my cable from Centurion solar today, to connect to the Pi, and will probably just use the percentages on the app,but shouldn't back to grid voltage be much lower if you do decide to take it down to 5%?
