Hello, With the Pytes V5a, the maximum charging current (CCL) is sometimes already reduced to CCL/V5a = 5A at 65% SOC. If you then discharge briefly - and then charge again, it works again for a while with a higher charging current. Initially, my assumption was that this was caused by the ambient…

today charging current was reduzed @90% SOC I think thats normal behavior ?

Yes, it’s normal that the battery starts to reduce the CCL at around 90%. I installed a system last week and that does the same.

What do you recommend on the max. charging current?

Good Morning The last few days i let the BMS manage The day bevor yeasterday it had a effect during discharging: in 12 minutes, the SOC dropped by 32%. The current was averaging around 43A, for 12 minutes → 9Ah → 9% SOC, and not 32%. [Entladen_@40A] Then in eavening the SOC was “frozen” at 20…

Hello everyone! I have the same problem with my V5 Pytes battery. It has been working for a week but it keeps shutting down at 5A at around 50%-60% SOC. It comes back on at the end of the day as the voltage drops. Did you find out what the problem was? Thanks! PKG [SOLARMAN Smart_18_01]

[image] PKG: week but it keeps shutting down at 5A at around 50%-60% SOC I have an inkling it could be an strange response to parasite loads/charge Or likely a SOC tracking problem. In other words it has its soc wrong for it’s voltage. In short a firmware problem. What you would ideally wa…

Dear i updated Firmware to the newest Version 1.10.25.C16 Now there is a limitation of charging current @60 SOC to 10A, before 5A There was a jump from 60% SOC to 100% within few minutes I think BMS Softare is crap [10A begrenzung] [soc_sprung] My dealer says a software update will be avail…

Nice feedback. The jump up when charge current falls is not as uncommon as you think. I do know a few brands that do this. You can even simulate it on a bmv with bad settings. Hopefully though they can tame it from the 50 to 100%. I mean surely a certain target voltage should be met before synch…

I still hope the promised Pytes update solves my problems.
