I have several Pylontech UP5000 installations, from 5KVAh to 40 KVAh. What I see is that I can never achieve maximum charge/discharge current specified, because CCL and DCL limits them. This happens not only at a certain temperature or when batteries are achieving maximum or minimum SOC%. That could be understandable. But an UP5000 has a 50 Amps standard charging specs and also a 0,7C for 5 minutes, 0,89 C for 60 seconds and a 2C for 15 seconds. Also there is info of lifecycle impact when you charge or discharge batteries to more than 0,5C. Bute I cannot achieve anything more than 0,5C CCL or DSL. I don´t believe BMS is allowing that. At least I coudn´t achieve those specs. Do you know if those limits can be changed? Even at owner decision to reduce SOH of batteries.
Also noticed in in article: https://www.victronenergy.com/live/battery_compatibility:pylontech_phantom#the_maximum_charge_and_discharge_current_is_limited_to_25a_but_the_data_sheet_tells_me_the_maximum_is_100a
In Hardware protection points states, within 5.3 chapter:
"Over-charge and Over-discharge Current Limit 102A for 15 seconds, 200A for 0.1 seconds and 400A short circuit current." So seems that these limits are able to be achieved. But are they working while CCL and DCL limits far below them.?
