Battery SOC minimum %

@AchmatK has pylons and has had no issues.
6 x pylontech batteries

3 x US3000B installed June 2020 when the system was installed

1 x US3000C installed March 2021

1 x UP5000 installed April 2022

1 x UP5000 installed July 2023

SOH on the entire battery bank is sitting at 91% after 5 years with all batteries counting ±0.8 cycles daily.

DOD is set to 10%.

I'll just add another couple of UP5000 batteries if I need more capacity.

Nice. I personally wouldn’t buy pylon batteries after the research I did to get Lithium batteries for my Dad. But what I found is probably the minority. Didn’t want to risk it for him. Dyness is what I got for him. Not much if any complaints online.

This is a few items that scared me away from Pylon.


Can’t find the thread I was surfing on Powerforum but it’s similar issues to the ones on the one above.

Pouch cells seems to be the culprit as one user here pointed out.

Found the thread. Swollen cells again. His were about 6 years old. Prismatic screw on type cells are the way to go.

Also seems to be when coms setup with deye and sunsyk they seem to overcharge vs when you just run it with normal voltage

Yeah. It may be better to let the inverter control the charging rather than through comms.

It’s like the Pace BMS issue on the video done by offgrid garage. The BMS is falsely reporting how many batteries are connected so it will tell the inverter that there is 2 batteries when here is 1 for example. Keeps the charging current for 2 when it’s just 1 battery that is connected.

I always knew that I would want to add more batteries to the initial 3 I bought and pylontech was the only battery manufacturer at the time that specifically stated that their batteries could be mixed with different capacities so opted to go with pylontech.

Seems like only the US2000 batteries. 20230703_175729.jpg20230706_123818.jpg
 
Just checked how the batteries are being discharged and the BMS seems to manage discharge rates drawing more from the newest battery while the 3 from when it was new is being discharged at a lower rate.

Probably due to them having lost more capacity over the 5 years. Screenshot_20251219_212659_Chrome.jpg
 
Might have to do that cause just balancing when charging is a issue of its a really unbalance battery. Had a takealot 5kw battery that was out of balance. Took ages but using lead acid mode I got it fixed.

Else it will charge trip OVP and report 100% soc and stops balancing.
Set bulk pack voltage to whatever it was when cell peaks? Then hurry up and wait?
 
Ohh okay then my Ecco must also have a Pace BMS. It's exactly like the Must battery :D

Nice. Connected with the Paceex app via bluetooth.
These stats are useless at 70% SOC. What are your balancer settings?

Take another screenshot at 55.2V. Hopefully there is a screen showing top cell balancing?
 
Yeah I was getting a bit happy about the Pace BMS reading peoples stuff here but nah. JK is still king. Pace has too many bugs. I guess that’s why it’s used in all these cheap lithium batteries out there.

Trust me, I've been an avid follower of Andy since the beginning. I love his channel because he thinks like me and tests all the options, good or bad, and so far JK is king.

Remember the good old days when you had the spinny meter and boobed the **** out of the system in the beginning?

Pylon would have solved many problems by just making it 16S like everyone else.
