I'm an Off-Grid user with no AC-Input, so would like to confirm if can be done option 2), or is mandatory follow option 1) procedure (Very Good Sunny Day). I did not find a Pylontech Official Procedure. Regards! and Thank You! I did option 2. Two new batteries came about 50% charged on delivery. Set DoD on my inverter (luckily I am on-grid) to discharge my existing two down to 50% over night. Inverter left batteries on around 49% though. Connected the 4 batteries together the next morning. Took less than 15 minutes to balance. Then hooked them all up to the inverter.

Turned out my older 3 were running v1.3 and the latest one v2.4. Upgraded all of them to v2.8 tonight without problems - and now all data is reported as should be I have a question...I have 4 batteries in my bank...Must i disconect each battery before the update and reconnect it back to bank...Or can I upgrade firmware even if batteries is still connected as bank?

I would disconnect each battery and upgrade them individually.

Don't know the answer to that I did the firmware upgrade when I was making changes to my system. I disconnected each battery and ran the update on each separately
