November 14, 20232 yr I am busy building myself a Pylontech battery bank and was wondering about the discharge rates when using a mixture of models. Currently I have 2x US 3000C's and 1x UP 5000... I know the US 3000C has a discharge amperage of 37A each and the UP 5000 of 50A. Does this mean when running all together, I will have a total of 124A or would it drop the UP 5000 to match that of the 3000s and result in a 111A total? I have checked the BMS screen on my Sunsynk inverter and it says 124 but I had read a while back that it would drop them to all match. Main reason for asking is the idea was to purchase different sizes as I found decent 2nd hand ones to expand affordably and I wanted to add some US 2000s but don't want to cripple my system with a 25A limit per battery. At the moment, I can test the total 124A as it is connected to a 5KW inverter which maxes out at 100A - first world problems 🤣 (All batteries are connected via a bus bar, so I am not worried about the individual cables and being daisy chained)
November 14, 20232 yr Hi jay-Dee. The Pylontech batteries will share the current between them, the up5000 battery will delivery more amps than Us3000. US3000 37AMP EACH UP5000 50 AMP EACH. One of my friends setup is an old 2000b and Up5000 connected together and the Up5000 delivers almost double the amp and also charges with double the amps.
