The grid is connected yes With those settings the uses the battery to help the grid up to the SOC specified then it stops using the battery until the next time slot, it works perfect if i have charge enabled for those times but if i use it like that and have load shedding my battery drops below and then fills my battery's with disgusting Eskom power. CT is definitely working only showing 0 because the inverter gets disconnected from the grid (The problem im having) No faults on the inverter We have a normal meter, dont think there is anything smart about it

Should not matter as Parallel is not ticked

No idea, How it was setup by the installer, who also messed up a bunch of other things, can i change it to master

.

Yeah like i mentioned it does not happen if i have charge from grid ticked on my system time settings, Very odd

Thanks please find above two posts

Just got another disconnect at 17:05 / 17:06

As time goes on i will get more data here one where a disconnect happened Thanks

Hi, 5kw sunsynk inverter 2X 5.32 sunsynk batteries So i am trying to identify the cause here, I get random disconnects at night when i discharge my batteries then reconnects after the set 60 seconds, I have checked grid stability is not to blame here, grid is perfectly stable before every disconnect, It does not happen when i have selected charge from grid in my system settings, but i dont want dirty Eskom power in my batteries so i leave this off. Only charge from solar. I have a feeling its got something to do with my battery settings, see below, let me know if this is correct. The grid start in particular: Another theory is its because my CT coil is 25 meters away but i don't think a CT coil reading will disconnect the grid, otherwise it is working and is connected the right way arround. Thanks

I dont have the rack mount batteries, the model i have does not have a dip switch, im pretty certain

I understand, Why is there an option to update the firmware then, Like will Sunsynk then rather not advise updating batteries firmware?

Does anyone know if the Batteries should be upgraded in stages or can you take it straight to the latest version? How do you even know what version they running?

Thanks for the good info, definitely gives me some peace of mind, Yes cap is set at 208 Also interesting fact is, the installers didn't really know what they where doing, CT Coil was reversed i had to explain that to them so they could fix They lost their mind when my non-essentials (GRID) where at 9kw, had to explain to them them that's not a problem its read from CT I had to set up the inverter to power my non-essentials via PV after i asked them to fix the CT coil Master and slave configuration was not set correctly on bat, see below So on the batteries i had this problem that they only want to pair up correctly if i use the left battery as the master, the installers had the right as the master and it wasn't really working because it wouldn't power them both on or off by powering the master on/off. I swapped the cam and link cables so the other one is the master and now i can power them both on and off by powering on/off the new master Point being i do think there is a firmware mismatch Way to worried to get the original installer to to the upgrade and i don't trust any of there Cowboys not sure what im going to do, i will call around i guess and see who knows the most about the topic.

Hi Hendrik, Thanks have a look below:

Thanks for the feedback, i will dig into it when i have time again,
